In this genus, the basal carina of the pronotum is complete. Although fine, it extends without interruption along the entire posterior margin. Each eye is narrowly separated from the base of the mandible by a distance subequal to the width of the basal maxillary palpomere. Each tibia is armed with a terminal spur. The rectangular lobe at the apex of the male abdomen is conspicuous. The aedeagus is asymmetrical and with the distal portion spatulate (Fig. 1g–i). This suite of characters distinguishes this genus from other genera. In the three known species, the color pattern is distinctive (Fig. 1a–c), with five long, dark stripes on each elytron (one sutural, one lateral, and three discal).</p><p>Using the dichotomous keys of Wilcox (1965), Clark (1998), or Riley et al. (2002), this genus would be identified as Triarius . However, it can be distinguished from that genus by the characters mentioned above.</p><p>Description. Form elongate oval (Fig. 1a–c). Each frontal tubercle subrectangular, transverse, about twice as wide as long, with acute extension at anterior angle mesad of antennal fossa, narrowly meeting other frontal tubercle at posteromesal angle, delimited laterad by shallow depression, delimited posteriad by abrupt depression; genae short, with length subequal to width of basal maxillary palpomere; eyes separated from antennal fossae by distance subequal to width of antennomere 2; antennae nearly filiform. Pronotum with long seta at each anterior and posterior corner; lateral margins strongly carinate, lined with several short setae; anterior margin lacking carina, with dense row of short setae; posterior margin with narrow carina, lined with dense row of short setae. Elytra with humeri well-developed; basal calli weakly developed, not delimited behind by depression; epipleura broad in basal half, extremely narrow in distal half. Prosternal process narrowly separating front coxae; procoxal cavities open behind. Terminal ventrite of male strongly impressed, with large rectangular lobe at apex.

We examined two syntypes of M. vittipenne in the Horn Collection (MCZ). Both are female. One of them bears the following three labels: “Tex,” “ LectoType 3795,” and “ Malacosoma vittipenne Horn. ” It is not clear who added the lectotype label to the specimen, and, to our knowledge, a lectotype designation has never been published.

Triarius mexicanus Jacoby, 1887 (by monotypy).</p><p>Diagnosis. The basal carina of the pronotum is complete. Although fine, it extends without interruption along the entire posterior margin. Each eye is narrowly separated from the base of the mandible by a distance subequal to the width of the</p><p>basal maxillary palpomere. The length of the basal antennomere is subequal to the maximum diameter of the eye. The epipleuron is broad in the basal portion and very narrow in the distal portion. Each tibia is armed with a terminal spur. The rectangular lobe at the apex of the male abdomen is conspicuous. In these characters, Triarius is similar to Triariodes. However, the frontal tubercles of Triarius are only about as broad as long, being limited laterad by a shallow (sometimes rather inconspicuous) depression. In Triariodes, the depression is nearly absent, such that the tubercles are strongly transverse, closely approaching the eye. Moreover, the aedeagus of Triarius is symmetrical, with the distal portion only weakly spatulate, or not at all.</p><p>Comments. Within the subfamily Galerucinae, the nature of the tarsal claws (simple, appendiculate, or bifid) is extensively employed to diagnose genera or even taxa above the generic level. It is therefore remarkable that some species of Triarius have bifid claws and others have appendiculate claws. However, this situation is not unique among the New World genera in the section Scelidites, where claws are reported to be appendiculate, except in some species of Triarius . Although not previously reported in the published literature, the claws are also bifid in Scelida metallica Jacoby, while appendiculate in all other species of Scelida Chapuis. Beyond the section Scelidites, the lack of claw uniformity is not common, but also not unprecedented. For instance, all species of Erynephala Blake and some (but not all) species of Monoxia LeConte have bifid claws in males and simple claws in females. In males of Hyperbrotica Bechyné and Springlová de Bechyné, all claws are appendiculate in females, while only the hind claws are appendiculate in males, the others being bifid.</p><p>KEY TO THE KNOWN SPECIES OF TRIARIUS</p><p>1.

The tarsal claws of this species are bifid. Also, the dorsum of the elytra is either entirely yellow or yellow with a dark sutural stripe; lateral stripes are absent or confined to the epipleura and adjacent areas; no posthumeral stripes are present. This suite of characters distinguishes this species from all other New World species of Scelidites. Specimens measure 3.5–7.6 in length.</p><p>Type Material Examined. We located eight syntypes of T. mexicanus (five MCZ, three NHMUK). One of the specimens (NHMUK), a male, bears a “type” label. This label is not necessarily an indication of the holotype, considering that Jacoby often put such labels on multiple specimens in the type series of a single species. In any case, this specimen is here designated as the lectotype. We also examined the female holotype of P. livida (MCZ) , the male holotype and nine paratypes of L. nebrodes (USNM) , and the female holotype and six paratypes of T. suturalis (CASC) .</p><p>Type Localities. Phyllobrotica livida: “Arizona.” Triarius mexicanus: “ Mexico, Northern Sonora ” (according to Selander and Vaurie 1962, the type locality is actually in Arizona, in the Graham Mountains,</p><p>near Fort Grant, and above Fort Huachuca]. Triarius suturalis: “Warren, Arizona.” Luperodes nebrodes: “Downings Ranch, Terrell County, Tex.”</p><p>Geographic Distribution. We examined specimens from Apache, Cochise, Gila, Graham, Pima, Pinal, and Santa Cruz Counties in Arizona, from Grant, Hidalgo, Lincoln, and Otero Counties in New Mexico, and from Brewster, Crockett, Culberson, Jeff Davis, Pecos, Terrell, and Val Verde Counties in Texas.</p><p>As noted above, the true type locality of T. mexicanus (“ Mexico, Northern Sonora ”) is probably in Arizona. However, this species is otherwise reported from Mexico (Wilcox 1965; Riley et al. 2003; Ordó~ nez-Reséndiz 2008), even though we have not personally examined specimens from there.</p><p>Temporal Distribution. We saw adults collected from April to July.</p><p>Plant Associations. This species is reported from Dasylirion Zucc. and Nolina Michx. (Asparagaceae); Asteraceae (genus not specified); and Xerophyllum Michx. (Melanthiaceae) (Wilcox 1965; Clark et al. 2004). Included in the material we examined are specimens labeled “ Dasylirion flowers”, “flowering Nolina sp., prob. arenicola ”, “ Baccharis ” ( Asteraceae), “on blossoming Acacia greggii A. Gray ”, and “beargrass” ( Xerophyllum).</p><p>Comments. As here conceived, this species is quite variable in appearance. Future study may well prove that multiple true species are involved. Beyond the type material mentioned above, we examined 553 other specimens.</p></div>	https://treatment.plazi.org/id/434B8790CE30FFA19EB0FAD9D2FD2133	Public Domain	No known copyright restrictions apply.

The tarsal claws of this species are bifid. Also, each elytron is yellow, with a posthumeral dark stripe and a sutural dark stripe; no short median stripe is present (Fig. 2f). This species is very similar to females of T. nigroflavus, but the distal half of the hind femur is mostly pale, and the terminal abdominal sternite is entirely pale in most specimens examined, although nearly entirely dark in a few. We have not seen any specimens with the terminal sternite mostly pale but narrowly dark along the apical margin, as is the case in all females of T. nigroflavus we have seen. Specimens of T. melanolomatus measure 3.9–7.4 mm in length.</p><p>Type Material Examined. We studied the male holotype and one paratype of L. melanolomatus (CASC). Additionally, we examined nine specimens (BYU) that were determined as L. melanolomatus by Doris Blake and that have label data matching (or nearly matching) those cited with the original description of this species. Although not labeled as such, these are likely also paratypes. We also studied the male holotype (OSUC) and 40 paratypes (CASC, OSUC) of T. santarosarum .</p><p>Type Localities. Luperodes melanolomatus: “Pi~ non Flat, San Jacinto Mountains, Calif.” Triarius santarosarum: “Santa Rosa Mts., California.”</p><p>Geographic Distribution. We examined specimens from Coconino, Gila, Mohave, and Pinal Counties in Arizona, and from Imperial, Riverside, San Bernardino, and San Diego Counties in California.

The tarsal claws of this species are bifid. In males (Fig. 2d), the pronotum and elytra are black, and the head is reddish brown (sometimes dark basally). In females (Fig. 2e), each elytron is yellow with a lateral dark stripe that does not attain the epipleuron and a dark sutural stripe; no short median stripe is present. Also, the female terminal abdominal sternite is mostly pale but narrowly dark apically, and the distal half of the hind femur is mostly black. These characters</p><p>enable recognition of this species (males and females) and distinguish it from all other New World Scelidites. Specimens measure about 6.2 mm in length.</p><p>Type Material Examined. We studied the male holotype and one paratype of L. flavoniger (USNM). The holotype is adequately labeled with locality, date, and collecting information. However, the other specimen, although clearly labeled as a paratype, lacks a collecting label.Perhaps,the label was inadvertently removed and lost. Contrary to Blake’ s (1942) statement, the paratype is male, not female.</p><p>Type Locality. “El Toro, Orange County, Calif.”</p><p>Geographic Distribution. We examined specimens only from Orange County, California.</p><p>Temporal Distribution. We examined adults collected in May and June.</p><p>Plant Association. This species is reported from Adenostoma fasciculatum (Clark et al. 2004) . Specimens labeled with this association are included in the material we examined.</p><p>Comments. Blake (1942) based her original description of L. flavoniger on only two specimens, the male holotype and a paratype that she indicated to be female. In actuality, both specimens are male. This mistake has probably fostered the misunderstanding that the pronotum and elytra of females are like those of males, entirely dark. Contrary to this notion, the coloration is very different, as noted in the diagnosis above. In addition to the type material, we examined 21 other specimens.</p></div>	https://treatment.plazi.org/id/434B8790CE3EFFA29EAEFB04D2BA26E4	Public Domain	No known copyright restrictions apply.

However, this may not be a food plant. In a personal</p><p>communication from Edward G. Riley, who was one of the collectors of the very large series from the upper ridge of Lost Mine Trail, he wrote the following regarding these specimens:</p><p>“My colleague Brian Raber and I collected this species in large numbers from a single modest-sized Juniperus flaccida tree growing on the upper ridge near Lost Mine Peak, shortly before the terminus of the Lost Mine Trail. These beetles were nearly absent from adjacent trees of various species including another J. flaccida growing less than 15m away and Pinyon pine and another Juniperus species found in the immediate area. This particular tree, although located on a ridge top, was not particularly well positioned to receive a precipitation of wind-blown beetles from below, the phenomenon known to beetle collectors as a ‘blow up.’ Other J. flaccida trees were beaten during this day-long hike, none of which produced Triarius specimens. Mating pairs were not observed. My impression was that these beetles, for some unknown reason, were obviously congregating on this particular tree. Although a field-feeding test was not performed, I did not feel these beetles were feeding on the Juniperus . One explanation for the congregation could be that the beetles were preparing to spend the coming winter months among the evergreen Juniperus foliage. However, at present, there are no spring collections recorded for this beetle, and, even if there were, that alone would not explain why they congregated on a single tree.”</p><p>Etymology. The species epithet (“ texanus ”) refers to the state of Texas where these beetles were collected. However, it is a bit misleading in that it suggests that the beetles are distributed throughout the state, when they have actually been found in only two of the western counties. However, this epithet was used in a PhD dissertation (Clark 1987), and it is repeated here to avoid confusion.</p><p>Comments. Due to superficial similarity, this species is likely misidentified as T. lividus in some collections.</p></div>	https://treatment.plazi.org/id/434B8790CE3CFFA59E93FC4AD24A2025	Public Domain	No known copyright restrictions apply.

Later, Smith and Lawrence (1967) transferred it to the genus Diabrotica . However, in so doing, they created a secondary homonym with Diabrotica tropica Weise, 1916 . The fact that the 1916 species is now placed in Paratriarius Schaeffer does not diminish the homonymy, as the original combination was in Diabrotica . We here propose Diabrotica neotropica as a replacement name for Triarius tropicus Weise, 1921 .</p></div>	https://treatment.plazi.org/id/434B8790CE3AFFA59E8DFC8DD7DA21E6	Public Domain	No known copyright restrictions apply.

The tarsal claws of this species are bifid. Also, each elytron is yellow, with a sutural dark stripe (Fig. 2c), a posthumeral dark stripe, and a dark, short, oblique, median, subbasal stripe. Taken together, these characters distinguish this from all other New World species of Scelidites. Specimens measure 4.0– 7.1 mm in length.</p><p>Type Material Examined. We located four specimens from the type series in the Horn Collection (MCZ). One of them, a male, bears the label “ LectoType 3796.” However, it is not clear who added the lectotype label to the specimen, and, to our knowledge, a lectotype designation has never been published. In any case, this specimen is now designated as the lectotype for T. trivittatus .</p><p>Type Locality. “ Arizona, Pinal Mountains .”</p><p>Geographic Distribution.
