The avittate elytral vestiture and black to deep brown dorsal integument of P. anivallis are similar to P. stellata Young (Fig. 45). Some specimens of P. anivallis have discontinuous elytral vittal fragments with edges coarsely eroded (Fig. 5), whereas, males of P. stellata have at most small, irregular-shaped spots of contiguous to imbricate squamae in normally vittate areas. In addition, protibial dentition in male P. stellata varies from bidentate to tridentate (bidentate in P. anivallis); and lacks the cristate elytral sutural apices of P. anivallis. The presence or absence (presumably abraded) of elytral discal setae is variable in P. stellata (present in P. anivallis). Both species share a mixture of white and pale yellowish-brown elytral squamae; presence of pronotal and pygidial setae; and similar ecological requisites: P. stellata is associated with sandy alluvial substrates of the American, Sacramento, and San Joaquin River Deltas, Contra Costa to Sacramento Counties, California (La Rue 1998) while P. anivallis is restricted to a geographically isolated sand dune complex in the Chihuahuan Desert of southwestern New Mexico. These morphological similarities may be the result of identical adaptive solutions to similar environmental pressures prevalent in psammophilous ecosystems.</p> <p>In dorsal habitus and distribution, P. anivallis may be confused with avittate concolorous P. diffracta (s.l.). However, that species is devoid of elytral setae; has light yellowish brown to dark brown (rarely olivaceous) integumental color; white (rarely yellow) squamae; and absence of acuminately produced elytral sutural apices. Ecologically, P. diffracta (s.l.) is a highly facultative species.</p> <p>Natural history. Polyphylla anivallis is ecologically associated with relictual pinyon-juniper-oak woodland refugia growing in deep semi-stabilized, low relief sand dunes (Lanner and Van Devender 1981; Thompson and Anderson 2000; Smith and Farrell 2005).</p> <p>Adult emergence of P. anivallis is apparently prompted by the onset of the summer monsoon that typically begins during July, indicative of “phenotypic plasticity” (i.e. any change in an organism’s characteristics in response to an environmental signal, Schlichting and Smith 2002). Earlier collection attempts during the drier months of May and June were unsuccessful. At the time the type series was collected, during late July, there were standing pools and puddles of monsoonal rain throughout the area and the sand was damp to a depth of 2 to 7 cm. Just prior to dusk, in faint diffused light, males were observed flying rapidly in open areas between dune vegetation approximately one meter above the sand surface. Most males were attracted to a 175 watt mercury vapor light station while other males were encountered crawling on the sand surface after twilight. Females are unknown and presumed flightless.</p> <p>Ecology. Animas Valley Sand Dunes (Fig. 50–51) are located in the Chihuahuan Desert of southwestern New Mexico, 1580 m elevation. The northwest-southeast oriented basin where they occur is bordered on the west by the Peloncillo Mountains and the Animas, Pyramid and San Luis Mountains to the southeast. Due to internal drainage, most of Animas Valley contains fine textured Pleistocene alluvial deposits (Kottlowski 1965). Sediments and alluvia, including those from two ephemeral playas, remnants of Pleistocene Lakes Animas and Cloverdale, are subject to saltation by southerly prevailing winds and subsequent downwind accretion at the southeast margin of the valley. These accumulations form diminutive rounded lunette dunes in an elongated arcuate-shaped mass which essentially follow the basal contours of the southern Animas Mountains. The pale ecru sand color is a result of this amalgam of aggregates.</p> <p>A complex of transitional floristic elements representing Chihuahuan desert scrub, oak savanna, oak woodland, and pinyon-juniper woodland occur near or within the dunes. Dominant vegetation in the immediate habitat includes Quercus sp. (oak: Fagaceae), Pinus engelmannii Carrière (apache pine: Pinaceae), P. leiophylla var. chihuahuana Englemann (chihuahua pine: Pinaceae), Juniperus deppeana von Steudel (alligator juniper: Cupressaceae), Arctostaphylos sp. (manzanita: Ericaceae), scattered Yucca sp. (Asparagaceae), with an understory of numerous forbs and grasses depending on precipitation levels.</p> <p>Climate is characterized by high amounts of solar radiation, wide diurnal ranges in ambient temperature, low relative humidity, and highly variable precipitation with subsequent elevated rates of evaporation. The dry early summer months of May and June are typically the hottest part of the year with average temperatures of 16° to 32° C. Winters are generally cool with average daytime temperatures between 4° and 14° C., and occasional snow at higher elevations. Average annual precipitation of 24 to 38 cm primarily occurs during July through September as brief localized convective thunderstorms. As much as 90% of annual rainfall occurs during this period (Holmgren et al. 2003).</p> <p>Conservation. Because of varied topography, unique floral diversity, and geographic isolation of Animas Valley, the ecoregion is recognized as a refugium for many threatened and endangered indigenous species (Dinerstein et al. 2000). The area comprising the type locality is under the jurisdiction of the Diamond-A-Ranch (formerly the Gray Ranch) which is administered by the Animas Foundation, a private conservation agency dedicated to protecting the abundance of biological diversity and natural and historical values of the area. As a result, public access to the area is carefully regulated which affords P. anivallis some protection. However, because of its apparent endemicity, P. anivallis should be considered a species of “special concern.”</p> <p>Etymology. From a combination of the prefix of “Animas” and the Latin vallis, “valley.”</p> <p>Common name.

The coarsely eroded elytral vittae, deep rufotestaceous integument, and eastern California distribution of P. koso are similar to its adelphotaxon, P. aeolus. However, males of P. aeolus have pale yellow setae; a combination of pale yellow or white squamae (setal and squamal vestiture white in P. koso); interstitial squamae contiguous with elytral vittae (intermittent in P. koso); elytral sutural vittae continuous and complete (fragmented and eroded in P. koso); elytral discal setae (absent in P. koso); and distinctly larger antennal structure than in P. koso. Ecologically, P. aeolus is a psammophilous obligate endemic to the Kelso Sand Dunes, San Bernardino County, California, whereas, P. koso is a montane isolate associated with relictual pinyon-juniper woodlands.</p> <p>In some respects, P. koso is similar in appearance to some phenotypes of P. arguta which lacks pronotal setae; has a light testaceous to black elytral integument; and is primarily restricted to the Great Basin in Nevada and Utah.</p> <p>Natural history. Males of P. koso were collected at mercury vapor lights in pinyon-juniper woodlands between 2100–2300 m during July with one record during early June. Other specimens have been collected during early August (Ballmer 2003). Polyphylla koso is sympatric with the southwestern montane form of P. decemlineata.</p> <p>An unidentified species of Pyrgota Wiedemann (Diptera: Pyrgotidae), a dipteran genus of endoparasitoids of Melolonthinae, has been observed to parasitize P. koso while avoiding the more abundant P. decemlineata (G.F. Pratt, in litt.). Typically, the female pyrgotid oviposits on the exposed abdomen of the beetle while in flight possibly utilizing one or a combination of olfactional mechanisms, microhabitat association, or synchrony with the host life cycle to localize and distinguish its preferred host. Pratt (1943), Young (1967, 1988), Salehi (1984), and Skelley (2009) described similar dipteran parasitism on other Polyphylla species.</p> <p>Ecology. The Coso Mountain Range is located in the Mojave Desert in east central California with elevations from 610 to 2490 m at Coso Peak. These remote mountains are part of the Great Basin “sky island archipelago,” a complex of high desert ranges that were geographically and ecologically isolated during the Pleistocene (Heald 1951; Smith and Street-Perrot 1983; Warshall 1995; Baldwin and Martens 2002). Because of an array of soils, microclimates, and topographic complexities, these isolated mountain ranges provide habitats for many rare and endemic species and are among the most biodiverse ecosystems in North America. Consequently, their associated faunas are highly divergent from other closely related taxa (Marshall 1957; MacArthur and Wilson 1963, 1967; Warshall 1995; Coblentz 2005).</p> <p>At the type locality, Coso Bridge (Fig. 52), southwest of Coso Peak at approximately 2286 m elevation, Pinus monophylla Torrey and Frémont (single-leaf pinyon: Pinaceae) is predominant with a mixed understory of Artemesia tridentata ssp. Nuttall (big sagebrush: Compositae), Eriogonum nudum Bentham (naked buckwheat: Polygonaceae), E. umbellatum Torrey (sulphur-flower buckwheat: Polygonaceae), E. wrightii Torrey ex Bentham (wright’s buckwheat: Polygonaceae), Purshia glandulosa Curran (desert bitterbrush: Rosaceae), and Ribes velutinum E. Greene (desert gooseberry: Grossulariaceae) (G.F. Pratt, in litt.).</p> <p>At Mill Springs (Fig. 53), approximately 2130 m elevation where a single specimen was collected in early June, vegetation is primarily Juniperus occidentalis Hooker (western juniper: Cupressaceae) (G.F. Pratt, in litt.).</p> <p>Because the mountains lie within the rain shadow of the Sierra Nevada Range, annual precipitation averages between 12.5 and 30.5 cm. Much of this occurs as snow at higher elevations which is often present until late spring. Average annual temperatures range from 4.0° to 19° C., with 125 to 250 frost-free days. Soils are well drained with rapid surface runoff from alluvial fans that lead to either the adjacent Owens or Panamint Valleys.</p> <p>Despite the generally dry conditions, the areas surrounding Coso and Mill Springs support areas of unique flora including species that exemplify vastly disjunct distributional ranges (G.F. Pratt, in litt.). In arid regions where moisture availability constrains species distributions, a locally damp site will act as an ecological refugium.</p> <p>The Coso pinyon-juniper woodland represents a relictual population of a more widespread coniferous forest that dominated much of southwestern North America during the Pleistocene. Polyphylla koso may have been more widely distributed at that time when this region of eastern California was a broad savanna dominated by shallow pluvial lakes with scattered woodlands occurring at all elevations (Axelrod and Ting 1960; Woodcock 1986; Mensing 2001). As climate transitioned to interstadial conditions between 14,000 and 10,000 years ago, large contiguous areas of cooler temperate habitats were fragmented into mountain-top refugia and replaced at lower elevations by a cactus-legume-dominated desert scrub (Wells and Woodcock 1985; Thompson et al. 1993; Thompson and Anderson 2000).</p> <p>Conservation. The distribution of P. koso lies within the boundaries and jurisdiction of the China Lake Naval Air Weapons Station. As a result, public access to the area is extremely limited which affords it some protection. However, because it occupies a very limited geographic range, P. koso should be considered a species of “special concern.”</p> <p>Remarks. Polyphylla koso is the second species of Nearctic Polyphylla restricted to a small area of an isolated mountain complex. The other species is P. hirsuta Van Dyke (1933) of the Patagonia Mountains, Santa Cruz County, Arizona.</p> <p>Although the type locality of P. barbata is “Mt. Hermon, Santa Cruz County, California ” (Cazier 1938), the name “Mount Hermon” was chosen for a Christian retreat site for its biblical significance rather than montane characteristics (elevation 178 m).</p> <p>Etymology. From the Tümpisa Shoshone language, kosoowah meaning “to be steamy,” referring to the numerous hot springs throughout the area and its indigenous paleo-inhabitants, the Koso. The name is applied as a noun in apposition.</p> <p>Common name.

The combination of deep olive green dorsal coloration; sparsely distributed yellowish-brown elytral interstitial squamae (Fig. 18); reddish-brown to deep yellowish-brown setae; narrow elytral vittae with coarse edges; evanescent submarginal vittae; and long, densely distributed pronotal setae (Fig. 15–16, 19) are sufficient to distinguish P. morroensis from all other species of Polyphylla.</p> <p>Polyphylla morroensis may possibly be confused with P. crinita or its adelphotaxon, P. nigra, that are similar in general appearance. Males of those species have a black, reddish-black, or brown (sometimes olivaceous yellowish-brown in P. crinita) dorsal integument; pale yellow to yellowish-brown setae; densely distributed elytral interstitial squamae (Fig. 17); elytral vittae with sharply defined (P. nigra) or uneven (P. crinita) edges; submarginal vittae longitudinally complete; and sparsely distributed pronotal discal setae. The presence (LeConte 1856; Horn 1881; Casey 1914; Fall 1928, Hardy 1981) or absence (Young 1988) of pronotal discal setae in male P. crinita is apparently subjective and open to interpretation as is the presence of elytral discal setae (present in syn. P. ruficollis perversa Casey 1914).</p> <p>Both P. crinita and P. nigra are distributed from the Pacific northwest to Baja California, Mexico, and are associated with a variety of habitats including mixed conifer forest, mixed riparian woodland, ancient volcanic soils, and urban environs indicating diverse facultative ecologies.</p> <p>Due to its littoral proximity, the dark olive green coloration; reduced, sparsely distributed interstitial vestiture; and narrow, eroded vittae of P. morroensis may be a selective response to the cooler, moist, coastal environment.</p> <p>Natural history. Males of P. morroensis were collected at lights of private dwellings and a shopping center complex immediately adjacent to areas of open Baywood Fine Sands habitat. Females are presumed flightless as none were encountered at lights but were found within their burrows 5 to 7.5 cm below the soil surface by observing male flight behavior. Polyphylla decemlineata was encountered in the coastal-dune scrub floral community south of the Baywood Fine Sands ecosystem but was not sympatric in the known distribution of P. morroensis (M. Walgren, in litt.).</p> <p>Ecology. Baywood Fine Sands (Fig. 54–55) are located on the southeast shore of Morro Bay, San Luis Obispo County, on the central California coast. The sand dunes were deposited during the Pleistocene when eustatic sea levels were approximately 10 to 170 meters lower than at present exposing continental shelf sands to eolian accretion further inland (Cooper 1967; Orme 1990; Knott and Eley 2006).</p> <p>The sand appears dark grayish brown to dark brown with fine particle size corresponding to high organic content. These deep, well drained soils provide the foundation for an endemic coastal ecosystem that supports remnants of maritime chaparral and coastal-dune scrub floral communities including several federal- and state-listed endangered or threatened species.</p> <p>Areas of maritime chaparral are dominated by a dense canopy of Arctostaphylos morroensis Wieslander and Schreiber (morro manzanita: Ericaceae), a federally endangered species. Understory vegetation is minimal as the environment under this chaparral complex is one of negligible solar penetration and deep leaf litter. In some areas Ceanothus cuneatus (Hook) Nuttall (buckbrush: Rhamnaceae), Eriophyllum confertiflorum de Candolle A. Gray (golden yarrow: Compositae), Mimulus aurantiacus Curtis (monkey flower: Phrymaceae), Prunus fasciculata var. punctata Jepson (desert almond: Rosaceae), Quercus agrifolia Nee (coast live oak: Fagaceae), and Salvia mellifera Greene (black sage: Lamiaceae) are present (M. Walgren, in litt.).</p> <p>Coastal-dune scrub is the most imperiled habitat because of its location on relatively flat terraces adjacent to the Pacific Ocean where development is prevalent. During different seasons, Abronia umbellata Lamark (pink sand verbena: Nyctaginaceae), Amsinkia spectabilis Fischer and Meyer (seaside fiddleneck: Boraginaceae), Corethrogyne filaginifolia (Hooker and Arnott) Nuttall (california aster: Asteraceae), Ericameria ericoides (Lessing) Jepson (goldenbush: Asteraceae), Eriogonum parvifolium Smith (coast buckwheat: Polygonaceae), Eriophyllum staechadifolium la Gasca (yellow yarrow: Asteraceae), and numerous other ephemeral annual species predominate. The floral community is threatened by the invasive exotic, Ehrharta calycina Smith (veldt grass: Poaceae), which supplants native species and can cover the dunes in dense expanses (M. Walgren, in litt.).</p> <p>Ambient climate is characterized as subhumid mesothermal with cool, foggy summers and cool, moist winters. The climate provides frequent periods of fog drip that is a critical factor in limiting the distribution of endemic species of the ecosystem. Mean annual precipitation is approximately 37 cm at the coast to nearly 90 cm further inland. Average annual temperature is 5.5° to 26° C., with an average of 250 to 350 frost-free days. Elevation ranges from mean sea level in areas adjacent to Morro Bay, at the northwest margin of the dunes, to approximately 250 m in the southern dune area.</p> <p>Conservation. The major threat to P. morroensis is urban development. Much of the area with moderate topographic gradients supporting Baywood Fine Sands has been subject to unprecedented urban expansion. In addition to direct removal and modification of the habitat, development has had detrimental effects on the quality of remaining habitat including fragmentation, deterioration due to increased recreational activity, and the introduction of invasive non-native vegetation (M. Walgren, in litt.).</p> <p>Remnants of the dunes support several federal- and state-listed endangered or threatened species including Helminthoglypta walkeriana (Hemphill) (morro shoulderband snail: Helminthoglyptidae), Anniella pulchra Gray (silvery legless lizard: Anniellidae), Dipodomys heermanni morroensis (Merriam) (morro bay kangaroo rat: Heteromyida), Eriodictyon altissimum P.V. Wells (indian knob mountainbalm: Hydrophyllaceae), and A. morroensis, clearly emphasizing the unique composition of the ecosystem.</p> <p>Because of limited geographic range and imminent threat of extirpation from habitat modification, P. morroensis should be considered a “critically imperiled” species.</p> <p>Etymology.

With solitary pale setae. Legs. Protibial basal tooth variably developed.</p> <p>Diagnosis. The prominent white dorsal vestiture and dense continuous elytral vittae of P. socorriana are similar to some disjunct psammophilous populations of P. decemlineata with heavy white dorsal squamation (= syn. P. comstockiana von Bloeker 1939). However, P. decemlineata lacks pronotal and elytral discal setae (present in P. socorriana); has sharply defined, smooth-edged elytral vittae (uneven to eroded in P. socorriana); yellowish-brown to black integument (deep rufotestaceous in P. socorriana); and is a larger, robust species (length usually greater than 30 mm; type specimens of P. socorriana are between 22–27 mm).</p> <p>Specimens of P. socorriana exhibiting an abraded dorsal vestiture may be confused with P. crinita which shares a proximal but allopatric distributional range (Hardy 1981). That species has an olivaceous yellowish-brown to black integument (deep rufotestaceous in P. socorriana); yellowish-brown interstitial squamae (white in P. socorriana); and lacks the basally adjoined discal and subsutural elytral vittae. The presence or absence of pronotal discal setae is apparently variable in male P. crinita (present in P. socorriana).</p> <p>Although infrequent in some western clade species, the basally adjoined discal and subsutural elytral vittae of P. socorriana (Fig. 26–27) is statistically stable and diagnostic. In addition to the types, twelve of fourteen paratypes (85%) exhibit this character.</p> <p>The dorsal coloration of P. socorriana is presumably a selective response to the distinctive white sand color of the El Socorro Sand Dunes ecosystem and contiguous sand areas suggesting an adaptation toward parasematic crypsis.</p> <p>Natural history. Based on field observations and specimen data, P. socorriana is a psammophilous obligate ecologically associated with coastal sand dunes. Males were attracted to black, ultraviolet, and mercury vapor light stations placed adjacent to, or a slight distance away from, the leeward side of the dunes shortly after twilight. The allotype female was encountered crawling on the sand surface at dusk (R.A. Cunningham, personal communication).</p> <p>Locality data of the specimen excluded from the type series, “ 2.7 mi E. Ejido Bonfil, Rio San Rafael,” is slightly inland and ecologically dissimilar to that of the type series. This would suggest the possibility that P. socorriana may not be entirely restricted to a coastal ecosystem. However, the arenaceous substrates of Rio San Rafael, an ephemeral desert riparian wash that drains to the Pacific Ocean, are consistent with the psammophilous requisites of P. socorriana and may provide an ecologically suitable corridor for the species to disperse, albeit, marginally inland.</p> <p>Ecology. El Socorro Sand Dunes (Fig. 56–57) are located on the Pacific coast of the state of Baja California, Mexico, at an elevation of 10 to 45 m. Their pronounced white coloration is directly related to high carbonate content (aragonite and calcite) from skeletal marine invertebrates. High carbonate sand dunes are rare in North America occurring only along the Yucatan Peninsula, the Channel Islands of California, and Baja California (Muhs et al. 2009).</p> <p>The coastal strip from 32° to 29.5° north latitude, encompassing the type locality, has been documented to be an area of high floristic diversity with a conservation status of endemic (25%), sensitive (40%), or rare (35%) species (Johnson 1977; Riemann and Ezcurra 2005, 2007; Vanderplank 2010).</p> <p>Adolphia californica S. Watson (california prickbush: Rhamnaceae), Funastrum arenarium (Decaisne ex Bentham) Liede (talayote: Apocynaceae), Heteromeles arbutifolia (Lindley) M. Roem (davis gold toyon: Rosaceae), Rhamnus crocea insula (Kellogg) (buckthorn: Rhamnaceae), and Yucca schidigera Roezl ex Ortega (splinter yucca: Agavaceae) are found only on the El Socorro Dunes.</p> <p>Abronia maritima Nuttall ex. S. Watson (red sand verbena: Nyctaginaceae) is predominant on active dunes with A. umbellata Lamark (pink sand verbena: Nyctaginaceae), Atriplex julacea S. Watson (saltbush: Amaranthceae), Eulobus californicus Torrey and A. Gray (california primrose: Onagraceae), Funastrum arenarium Decaisne ex Bentham (climbing milkweed: Apocynaceae), Helianthus niveus (showy sunflower: Compositae), and Heteromeles arbutifolia (Lindley) M. Roem (toyon: Rosaceae) in stabilized dune areas (Vanderplank 2010).</p> <p>Ambient climate is classified as mediterranean (cool moist winters, hot dry summers) with average annual precipitation of approximately 13.5 cm and mean temperature of 17.5° C. The area experiences frequent moisture laden fog providing additional water resources and associated humidity which is critical in supporting the endemic species of the ecosystem (Markham 1972; Delgadillo 1998).</p> <p>Conservation. The unique high carbonate content, unusual floristic composition, high species diversity, and percentage of endemic taxa clearly indicate the El Socorro Sand Dunes a priority for conservation. The imminent threat to P. socorriana is habitat degradation. The entire dune system has been proposed for development to allow egress from Mexico Peninsular Highway 1. Other impending threats include trash dumping, recreational off-road vehicle use, invasive floristic species, and vegetation clearing (Vanderplank 2010).</p> <p>To underscore the negative impact of cumulative human encroachment and habitat modification of the region, the endemic tule shrew (Sorex ornatus juncensis Nelson and Goldman: Soricida) is now extinct and the San Quintín kangaroo rat (Dipodomys gravipes Huey: Heteromyidae) is presumed ex- tirpated as no individuals have been found since the 1980s (Best and Lackey 1985; Álvarez-Castañeda and Patton 1999).</p> <p>Because of limited geographic range and imminent threat of extirpation from habitat modification, P. socorriana should be considered a “critically imperiled” species.</p> <p>Remarks. Polyphylla socorriana is the second species of Polyphylla described from a coastal sand dune complex of the Baja California Peninsula. The other species is P. multimaculata Hardy (1981) from Dunas de Soledad, north of Guerrero Negro.</p> <p>The Polyphylla fauna of the Baja California Peninsula now consists of seven species. Of these, five also occur in the southwestern United States (P. cavifrons, P. crinita, P. decemlineata, P. nigra, P. rugosipennis Casey), and two are endemic (P. multimaculata, P. socorriana).</p> <p>Etymology.

CASC #15999 (not University of Idaho, Young 1986:49) [examined].</p> <p>Notes on synonymy. The basis for this synonymy is that the putatively diagnostic characters of P. ratcliffei (differences of parameres, protibial dentition, and geographic distribution) are within the range of morphological variation of P. avittata, as determined by comparison of the types and other material examined from several institutional and private collections.</p> <p>In the original description, Young (1986) stated that P. ratcliffei could not be distinguished from P. avittata solely upon external morphological characters. However, he separated the two species based on “unique” male parameres, differences in protibial dentition, and disjunct distribution: southwestern Utah (P. avittata) and east central Utah (P. ratcliffei). All three criteria are not diagnostic and vary intraspecifically as follows:</p> <p>Parameres. Young (1986, 1988) considered the parameres in P. avittata asymmetrical (“unequal” Young 1986). In caudal aspect, he regarded the tips as dorsally cristate (i.e. bearing a raised carina, what Young referred to as a “dorsal flange”) with apices adjoined distally, whereas, in P. ratcliffei, he considered the parameres symmetrical (“equal” Young 1986) lacking any raised carina with the apices clearly separated.</p> <p>Examination of geographically intermediate samples from Emery and Garfield Counties, Utah (21 males), 16 displayed some indication of cristate parameres. In all samples, the parameres were symmetrical with the dorsal surface obliquely depressed outward, in contrast to those illustrated by Young (1986:49 Fig. 7). Consequently, the genitalic differences between these two species are regarded as intraspecific variation and unreliable to validate species recognition on this character.</p> <p>Protibial dentition. Cazier (1938) and Young (1988) indicated that protibial dentition was rarely applicable in distinguishing species and rejected the character as diagnostic because of intraspecific and geographic variation.</p> <p>Hardy and Andrews (1978) stated that nine of twelve male paratypes of P. avittata exhibit an indication of a third protibial tooth, the other three apparently bidentate as in the holotype. Young (1986) remarked that protibial dentition of the holotype and four paratypes of P. ratcliffei varied from weakly (i.e. bidentate with some indication of a third protibial tooth) to strongly tridentate. Assessment of available samples clearly demonstrates that protibial dentition within these two species is entirely variable and without any geographic correlation. Eleven of 25 P. avittata examined showed a slight indication of a third basal tooth. The remaining 14 were bidentate as the holotype. Only one of four P. ratcliffei was distinctly tridentate with the remaining three samples bidentate. The third basal tooth indicated as a slight lateral flange. Geographically intermediate samples from Emery and Garfield Counties (19 males) were all bidentate.</p> <p>Distribution. The amended distribution (Fig. 28) establishes that both putative taxa are more widely distributed than previously recognized. As a result, distribution is irrelevant in separating these species as used by Young (1986, 1988). In effect, Young’s comparative material upon which P. ratcliffei was established actually represented geographical extremes of a single taxon, P. avittata. Accordingly, it is expected that with continued field efforts in intervening sandy environments, the distribution between both type localities will prove to be one relatively continuous track.</p> <p>In view of the continuity of variation among available samples, the amended geographical range, and the absence of other morphological characters to distinguish the two taxa, there are insufficient criteria to warrant their separation into distinct species. On the basis of the above analyses, P. ratcliffei is reduced to synonymy with P. avittata.</p> <p>Materials examined. In addition to the holotypes, 37 males labeled USA, Utah: Emery County, S.

The type locality of P. avittata, Hurricane Dunes, Washington Co., Utah (Hardy and Andrews 1978) has recently been modified to create Sand Hollow State Park, which includes a 1,322 acre reservoir. Although remnants of the former dune field remain, there have been no provisions to constrain off-road-vehicle use to specific designated areas. It is probable that this population of P. avittata has already experienced irreparable habitat degradation and is likely in imminent peril of extirpation.</p> </div>	https://treatment.plazi.org/id/57341F3144126F2CFF120D3DFA7B7538	Public Domain	No known copyright restrictions apply.

V. M. Tanner Collection, BYUC #25. Holotype. Male. [examined].</p> <p>Comments on the holotype. Male. Labeled (Fig. 37) [in descending order] (1) “Kanab, Utah ” rectangular, white, black type-set; (2) “Anson Call Jr.” rectangular, white, black type-set; (3) “3168” rectangular, white, hand-printed in pencil; (4) “25” square, white, black type-set; (5) “Type” hand-printed perpendicular at left margin, “ Polyphylla uteana Tanner ” with male gender symbol at lower left corner, rectangular, red with black border, hand-printed in black ink.</p> <p>No label reference to a collection date is present, however, Tanner (1928) stated “ July 13, 1927 ” as well as an additional collector: “D. Irvin Rasmussen.”</p> <p>The holotype is an aged specimen, abraded anterodorsally, with heavily worn protibial dentition, and the left apical fourth and fifth metatarsomeres missing.</p> <p>It is briefly characterized as follows: Length 25.0 mm. Greatest width 14.5 mm. Head and pronotum piceous; elytra deep rufotestaceous, grading to rufopiceous at humeri; pygidium, exposed abdominal sternites, and legs rufotestaceous; antennae and other appendages of head light testaceous; squamal and setal vestiture pale white; head and pronotum moderately to deeply punctate; clypeal disc shallow, anterior margin slightly emarginate and weakly reflexed, lateral margins parallel; maxillary palpomere-4 3/4 length of three basal palpomeres combined; head, pronotal, elytral, and pygidial discs bearing setae; elytral sutural apices feebly acuminose; disc nearly avittate, vittae heavily eroded; protibia bidentate, dentition widely separated, significantly worn (age and abrasion), indicated by short protuberances; tarsal claws with basal proximal tooth.</p> <p>Tanner (1928) stated “pronotum without erect hairs,” presumably referring to the central pronotal disc that is heavily abraded (Fig. 35). However, under magnification (10.5×), there are thin, recumbent, pale setae randomly distributed on the pronotal disc. Also, he regarded the protibial dentition as unidentate. Although heavily worn, there are two distinct remnants of dentition on each protibia.</p> <p>Taxonomy. According to the original description (Tanner 1928), P. uteana was based on a single male specimen labeled “Kanab, Utah.” Young (1967, 1988) synonymized P. uteana with P. diffracta based on the purported similarity of the “relative size of the antennal club, lack of elytral hairs, closely punctate pronotal disc, and a ‘unicolorous black’ (Young 1967) or ‘unicolorous brown’ (Young 1988) elytral coloration.” In comparing it to P. hirsuta, Young (1967) stated that P. uteana was “totally without vittae.”</p> <p>Contrary to Young’s observations, however, upon closer scrutiny and magnification (20×), there are, in fact, short, suberect, randomly distributed, pale setae present on the elytral surface of the holotype. In addition, the specimen is distinctly bicolored displaying a deep rufopiceous head and pronotum, and deep rufotestaceous elytra with vestiges of former vittae (Fig. 33–36), clearly in contrast to Young’s evaluation.</p> <p>The holotype of P. uteana is conspecific with, and well within the morphological range of variation of, specimens from the Coral Pink Sand Dunes, Kane County, Utah, approximately 12 km (7.5 air miles) west of Kanab, the type locality. In addition, molecular sequence data of mitochondrial 16S, COI, and COII cytochrome oxidase genes of this deme (Russell 2000) conclusively establishes the distinctness of this species and strongly supports reinstatement to species status.</p> <p>Remarks. The known range of P. uteana appears to represent a southwest to northeast morphological cline which also corresponds to the dune slip-face orientation and eolian migration alignment.</p> <p>Males from the southwest lower dune field (~ 1600 m elevation) (Fig. 40) display lighter integumental coloration (light testaceous to rufotestaceous); coarsely eroded, fragmented elytral vittae; lamellate antennomeres strongly recurved, nearly attaining a right-angle; and shorter overall body length (&lt;22.0 mm). Ecologically, this area is a mixed Mountain-Brush plant community primarily within semistabilized barchanoid dune hummocks.</p> <p>Males from the northeast upper dune field (~ 1900 m elevation) (Fig. 3–39) tend to be darker in coloration (deep rufotestaceous); consistently avittate; lamellate antennomeres feebly recurved; and greater in body length (&gt; 22.0 mm). Collection localities from this area are in pinyon/juniper uplands in stabilized or active parabolic and transverse dune types.</p> <p>The coloration of P. uteana closely resembles the distinctive sand color particularly during crepuscular hours, at low solar angle, when adults are most active suggesting predator evasion adaptations through parasematic crypsis or spectral properties in flight. For desert arthropods, crepuscular activity may be an effective way of avoiding thermal stress and/or predation while still utilizing available light.</p> <p>Based on morphological similarities, Tanner’s holotype was most likely collected somewhere in the northeast upper dune field within the Sand Hills region where large areas of arenaceous substrates are common. The specific locality of “Kanab, Utah ” may have been used simply because it was the closest point of reference since very few roads, towns or other geographic points were established in this area of south-central Utah during the early part of the twentieth century. This was common practice as early collectors and authors were less precise about specimen labeling methodologies as compared to modern standards. Usually, a nearby town, prominent landmark or geographic form were used as demonstrated by Tanner’s reference (1928), “about thirty miles southeast of Zion Park.”</p> <p>Materials examined.

Males were first observed flying at or just before twilight and continued late into the evening except on one occasion ceasing abruptly at 23:15 hrs. PST when no additional males were seen at light stations nor encountered upon the sand surface. Similar to the behavior reported for P. aeolus (La Rue 1998) and P. arguta (Young 1988). Although flight activity of P. uteana had ceased, males of P. arguta and P. decemlineata continued to be attracted to light stations for several hours.</p> <p>Approximately 20 minutes prior to dusk, preceding male flight, female P. uteana were found crawling or stationary on the sand surface with antennae extended and lamellae in a splayed position. Despite attempts to induce flight by releasing them just above the sand surface, females would not fly suggesting they are flightless as in other Polyphylla species restricted to cryptic ecosystems (La Rue 1998; Russell 2000; Skelley 2009). No adult feeding activity was observed and no specimen was encountered on vegetation. Adult longevity is presumably based upon metabolic reserves accrued during larval development. As in other psammophilous Polyphylla, adults of P. uteana undoubtedly spend diurnal hours at varied depths within the microenvironment of damp sand (La Rue 1998).</p> <p>Ecology. The Kanab and Coral Pink Sand Dunes are part of a larger sand dune regime located in the Colorado Plateau region of south-central Utah. The dunes are connected by sheet sand deposits to the Sand Hills region that extend northeast between Kanab Creek and the Sevier fault. Smaller sand accumulations have developed on the lee sides of numerous ridges, escarpments, and cliffs throughout the area. Estimates place the sand origin to the Pleistocene (Gregory 1950) or possibly during the middle Holocene (Shafer 1989). The salmon-colored sand is derived from a mixture of red and white Navajo Sandstone grains.</p> <p>The vegetation at Coral Pink Sand Dunes is largely transitional with elements of cool desert shrub, pinyon-juniper, mountain brush, and ponderosa pine floral communities (Welsh et al. 1993). Predominant species include Artemisia tridentata ssp. Nuttall (big sagebrush: Compositae), Juniperus osteosperma, and widely distributed Pinus edulis. A varied understory of extensive Calamovilfa gigantea (Nuttall) Scribner and Merrill (giant sand reed: Gramineae), Ericameria nauseous (Pallas) (rabbitbrush: Asteraceae), Sophora stenophylla A. Gray (fringeleaf necklacepod: Leguminosae), and Wyethia scabra Hooker (rough mulesears: Compositae), with many annual species present at various times of the year depending on precipitation levels.</p> <p>Climate is characterized as a cold desert (cold winters and hot, dry summers). Mean annual precipitation, which fluctuates greatly from year to year, averages 34.5 cm with occasional snowfall. In late summer, brief monsoonal cloudbursts are common. Ambient temperatures range from 7° to 32° C. In recent decades there has been increased available moisture but precipitation has become exceedingly variable (Welsh et al. 1993).</p> <p>Conservation. The major threat to P. uteana is habitat destruction from off-road vehicle activity which has greatly increased in recent decades. The use of three- and four-wheel off-road vehicles on the more vegetated dune areas adversely modifies and destroys critical habitat. Irreparable destabilization of vegetated dunes accelerates sand movement to a point that exceeds the tolerance of dune-adapted plants on which larvae of P. uteana are dependent. Surveys of other sand dune ecosystems in the Great Basin have established that P. uteana is endemic to a small region of contiguous sand dune areas in southcentral Utah. This would indicate that it is highly vulnerable to extinction from continued anthropogenic disturbance and should be considered a “critically imperiled” species.</p> <p>Common name.

Krell (2010) cites “Mesa County, Colorado.” Records of its occurrence in California (Young 1967, 1988; Evans 1992) certainly represent misidentified or mislabeled specimens.

Based on a series of 19 males, Young (1988) described P. mescalerensis from the Mescalero Sand Dunes, Chaves County, New Mexico. The female was subsequently described by La Rue (1998).</p> <p>In Young’s key to the North American species of Polyphylla (1988), the concluding couplet for P. mescalerensis (#18, p.24) includes the distributional note, “ Chihuahua, Mexico.” Inexplicably, no further reference to the Chihuahuan record appears anywhere in the publication nor, in the intervening years since Young’s publication, have any supporting references documenting its occurrence there been reported (Morón 1997, 2010, 2015 in litt.).</p> <p>A purported male specimen of P. mescalerensis examined is labeled “ MEX: Chihuahua, Cerro San Luis, VIII-13-1981, 1767m at light, S. McCleve // P. mescalerensis Young, det. R. M. Young 1988 ” (DALC). The coincidental year of Young’s determination suggests the possibility that this was a specimen on which he validated the Chihuahuan distributional record.</p> <p>Upon closer scrutiny, however, the Cerro San Luis specimen and samples from the Mescalero Sand Dunes differ in several salient morphological respects as follows:</p> <p>Mescalero Sand Dunes, New Mexico. (15 male topotypes) (Fig. 48). Dorsal integument light yellowishbrown to reddish-brown except head black; anterior clypeal margin moderately reflexed, lateral margins basally convergent; distal maxillary palpomere-4 conical, obtusely tapered at apex, surface coarsely punctate, with only a few randomly scattered golden setae; scutellum narrow, triangular; pronotum widest at basal 1/2, margins strongly explanate, discal setae sparsely to moderately distributed; elytral disc setose or glabrous (abrasion), posterior margins obtusely rounded; protibia bidentate to tridentate; meta-, mesotibia with two or three acuminate projections; antennae small, slightly to deeply recurved distally; ventral surface of protarsomere-5 smooth, lacking any serration.</p> <p>Cerro San Luis, Chihuahua, Mexico. (1 male) (Fig. 49). Dorsal integument deep reddish brown except head, lateral pronotal disc, and elytral humeri black; anterior clypeal margin weakly reflexed, lateral margins parallel; distal maxillary palpomere-4 acutely tapered at apex, feebly depressed dorsally, surface finely punctate, with very fine, short pale setae; scutellum transverse; pronotum widest at basal 1/3, margins feebly explanate, discal setae sparsely distributed; elytral disc glabrous, posterior margins recurved inward toward sutural apices; protibia bidentate, lacking any indication of a basal third tooth; meta-, mesotibia devoid of acuminate projections; antennae large, moderately recurved distally; ventral surface of protarsomere-5 with a raised serrated carina.</p> <p>Given the marked disparity of morphological and ecological factors and the absence of additional specimens confirming its occurrence there, the Chihuahuan record for P. mescalerensis is invalidated. Because only a single Cerro San Luis specimen is presently known, definitive taxonomic treatment must await additional material.</p> </div>	https://treatment.plazi.org/id/57341F31441C6F27FF120ADDFD927648	Public Domain	No known copyright restrictions apply.

Type locality: “ Arizona (Grand Cañon of the Colorado)” Casey (1914).</p> <p>This species is poorly represented in collections and little is known of its natural history or ecological associations. At present, the known distribution is significantly fragmented being recorded primarily from the Grand Canyon area of northern Arizona and the Sierra San Pedro Martir, Baja California, Mexico (Hardy 1981; Young 1988). The female remains unknown.</p> <p>The San Juan County, New Mexico, locality is in an area of Juniperus sp. and Atriplex canescens (Pursh) Nuttall (saltbush: Amaranthaceae), 1675 m elevation, associated with the Chaco Dune Field in northwestern New Mexico (Schultz and Wells 1981). Polyphylla decemlineata was sympatric at this locality (P.O. Kaufman, personal communication).</p> <p>Sego Canyon, Grand County, is in southeast Utah among pinyon-juniper-oak woodlands with scattered to dense stands of Artemisia sp. and Ericameria sp. growing in sandy alluvial soil.</p> <p>Seaman Spring, Kane County, is in south central Utah in an area of Pinus edulis and Juniperus osteosperma at an elevation of 1870 m.</p> <p>The combination of dark brown to black dorsal integument; presence of head, pronotal, elytral, and pygidial setae; rough-edged, incomplete elytral vittae; parallel lateral clypeal margins; coarsely punctate pronotal disc; comparatively small antennal structure; and bidentate protibia distinguish males of this species from sympatric congeners: P. arguta, P. decemlineata, P. diffracta, and P. hammondi. Of these, P. rugosipennis is most similar to P. arguta with which it shares a brown to black dorsal integument; white squamal vestiture; elytral vittae linear, whether continuous or fragmented, with edges coarsely eroded; and medium to large size (length usually greater than 25 mm). Polyphylla arguta lacks pronotal and elytral discal setae usually present in P. rugosipennis. However, the presence or absence of pronotal setae in P. rugosipennis is apparently variable (Casey 1914; Cazier 1938) as is their length either short (Hardy 1981) or long (Young 1988). All of the specimens cited here have short pronotal setae. Although male protibial dentition in P. rugosipennis is typically bidentate, one specimen from the Camp Christopher, Yavapai County, Arizona, series is distinctly unidentate without any indication of further dentition or excessive abrasion. Furthermore, the elytral vittae of P. rugosipennis may vary from nearly longitudinally complete to significantly fragmented and discontinuous. As a result of erroneous concepts and perfunctory “gestalt” taxonomy, the latter variation is frequently misidentified as P. diffracta. This variability in intraspecific morphology may possibly contribute to the species’ misidentification and explain its inconsistent distribution.</p> </div>	https://treatment.plazi.org/id/57341F31441F6F26FF12080DFC5675D8	Public Domain	No known copyright restrictions apply.
