Ground color on dorsum varies from dark reddish brown or black to yellowish brown or orange, opaque to weakly shiny, with extensive, opaque, pale yellow to ochre to orange to rarely grayish or reddish brown or almost cream white to black marks; marks in form of transverse or oblique bands or large, round spots on pronotum and elytra. Venter and legs vary from shiny black with variable, enamel-like pale yellow or ochre marks to completely enameled with dark punctures. Setae of venter and legs black or pale, rarely ferruginous. Head: Frons and clypeus vaguely tumescent at center or not, punctate. Clypeal apex slightly thickened, slightly reflexed, weakly emarginate. Antenna with 10 antennomeres, club subequal in length or slightly shorter than entire stem in males, slightly shorter in females. Pronotum: Surface with small to large, sparse to dense punctures. Elytra: Surface similar to that of pronotum. Sutural costa and sometimes costa on disc each elevated on apical halves. Apices at suture subquadrate. Pygidium: Surface with sparse to dense, crescent-shaped to transversely vermiform punctures or densely, transversely rugulose and with short, black or pale setae in pristine specimens. In lateral view, surface weakly convex in both sexes. Venter: Metasternum with moderate to large, sparse to usually dense, round to crescent-shaped, setigerous punctures either side of impunctate or sparsely punctate mesometasternal process. Mesometasternal process, in lateral view, short (not extending past apices of mesocoxae) to slightly longer; if longer, projecting slightly obliquely away from ventral axis of body, apex broadly rounded to subquadrate; in ventral view, sides taper to rounded apex. Abdominal sternites 1 – 5 of both sexes with small to moderately large, round to crescent-shaped punctures on lateral margins; sternite 6 usually with denser punctures.

0389C677FFA4167CFCD4EB8D188FFEF1.taxon	diagnosis	Diagnosis. The characters of most taxonomic value for distinguishing Marmarina species from other New World gymnetine genera are: lack of armature on the frons and clypeus (armature present in Chiriquibia Bates, Tiarocera Burmeister, Allorrhina Burmeister, and Cotinis Burmeister); clypeus weakly reflexed, slightly emarginate (deeply emarginate in Hadrosticta Kraatz, Amithao Thomson, Desicasta Thomson, and Guatemalica Neervoort van de Poll); prosternum with spur (spur absent in Hologymnetis Martínez); antennal scape not elongated (scape as long as next four antennomeres combined in Heterocotinis Martínez); dorsal coloring opaque with variable pattern of speckles, spots, or obliquely transverse bands on pronotum and elytra (pronotum and / or elytra with cretaceous bands or spots in Gymnetina Casey); dorsal surface lacking scales or dense setae (scales present in Balsameda Thomson, setae present in Hoplopygothrix Schürhoff and Neocorvicoana Ratcliffe and Micó); venter with weakly shiny, enamel-like coloring on shiny black ground color; mesometasternal process short and blunt, not or only slightly longer than apices of mesocoxae and subparallel to ventral axis of body or projecting slightly obliquely downwards (mesometasternal process large, subquadrate, strongly declivous in Gymnetis MacLeay); protibiae with apical tooth, occasionally with swelling behind apical tooth suggestive of a second tooth (that of M. parvula is weakly tridentate); metafemorae not enlarged (enlarged in Blaesia Burmeister, slightly enlarged in Halffterinetis Morón and Nogueira); posterolateral corner of metacoxa rounded to subquadrate, not acutely produced backwards; and apices of elytra at the suture rounded (acute or spinose in Hoplopyga Thomson). Like most other gymnetines, males are distinguished from females by having both spurs on the apex of the metatibia acute (bluntly rounded in females) and with the abdominal sternites usually distinctly concave (planar or tumescent in females). Natural History. Adults of Marmarina species are diurnal. Morón et al. (1997) reported adults have been collected from mature tropical fruits but rarely from rotting fruit traps, and that the larvae feed on organic matter beneath rotting logs or in the debris of ant nests of Acromyrmex species (Hymenoptera: Formicidae).	en	Ratcliffe, Brett C.

0389C677FFAC1673FD09EA8F1F66F99C.taxon	distribution	Distribution. Marmarina parvula is known only from central and northwestern Argentina in Salta Province. At present, there are no other Marmarina collecting records from the type localities, but the collecting data are too fragmentary to say if M. parvula is truly isolated from other species. Di Iorio (2013, figs. 129 – 132) illustrated four additional specimens from San Luis and La Rioja in western Argentina that could be conspecific with M. parvula. I attempted to obtain these on loan so that I might designate them paratypes if they represented M. parvula, but this was not possible due to the extreme difficulties of securing permits simply for sending specimens from and to Argentina (O. Di Iorio, personal communication to BCR, 27 October 2014). Locality Records. 6 specimens originally from AMIC and CMNC. ARGENTINA (6): SALTA (6): Ampascachi, El Carril (15 km S), Embalse Cabra Corral (Fig. 28). Temporal Distribution. January (2), February (1), March (3).	en	Ratcliffe, Brett C.

0389C677FFAC1673FD09EA8F1F66F99C.taxon	diagnosis	Diagnosis. Marmarina parvula is unique in the genus because of its small size (less than 11.5 mm), abdominal sternites longitudinally depressed at the center, and the distinctive form of the parameres with small teeth on both the mesal and lateral edges of the apex of each paramere (Fig. 26). These characters and those of the mesometasternal process will distinguish M. parvula from M. tigrina (compare Figs. 24 – 27 and 32 – 35). Natural History. The specimens were collected from habitats that are all xeric. One specimen was taken from an ant refuse pile (label data).	en	Ratcliffe, Brett C.

0389C677FFAB1670FF7FE98218DAFA6E.taxon	diagnosis	Diagnosis. Marmarina tigrina is identical with M. argentina except for the distinctive form of the mesometasternal process of both species (Figs. 32 – 33 versus Figs. 3 – 4). The large, thick, obliquely projecting process in M. tigrina easily contrasts with the short, blunt, subparallel process in M. argentina. The form of the mesometasternal process is important in the Gymnetini, and it is consistently expressed within any given species. Try as I might, I could find no other characters that would help to separate these two species, especially since each varies so much in color, pattern, and surface sculpturing. The orange-colored morphotype of M. tigrina is remarkably similar to Gymnetis hieroglyphica (Vigors) in color and pattern. Marmarina tigrina has apical angles of the clypeus noticeably narrowed and rounded, whereas those angles in G. hieroglyphica are nearly right angled, thus giving the apex of the clypeus a broader, subtruncate appearance. In addition, the pygidium and abdominal sternites in M. tigrina have the genus-typical, enameled yellow or orange color (often reduced in females), but the pygidium and sternites in G. hieroglyphica are black with small, opaque, orange flecks on the lateral margins of the sternites. Nomenclature. Marmarina tigrina shows great variation in color that ranges from light to dark sulfur yellow to orange to grey to nearly black, and also in the expression of its pronotal and elytral patterns that vary from sparse to dense. As a consequence, several names have been proposed for these variants, none of which constitute different species. Blanchard (1847) said of his G. touchardi that it was probably just a variety of G. tigrina, and of his G. albosparsa that it was probably just a smaller variety of G. touchardi and G. tigrina. These two Blanchard names are synonyms. Krajcik (1998) listed G. punctata Blanchard, 1850 as a junior synonym of G. tigrina, but the one line descriptor of this supposedly Mexican species in Blanchard (1850) cannot be reliably assigned to G. tigrina. Schürhoff (1937) correctly placed G. punctata as a “ subspecies ” of G. (now Hologymnetis) cinerea, and after examining the type in Paris, I confirmed that it is a junior synonym of H. cinerea (Ratcliffe and Deloya 1992). Burmeister (1866) noted there are specimens of G. tigrina that are totally black. In describing G. strobeli, Burmeister (1866) stated it was exactly like G. tigrina, but its black areas were lustrous and shiny as opposed to opaque. This character state is occasionally seen, but it does not constitute a different species. Marmarina litorea Schürhoff is simply an ochre or orange morphotype as opposed to the more commonly encountered yellow form, and it does not represent a different species. Natural History. Adults have been collected in accumulated vegetation in the nests of Acromyrmex lundi (Guérin-Méneville) (Berg 1890) and in the fungal nests of Acromyrmex species in Argentina (label data and A. Martínez, personal communication, April 1979). Navarrete-Heredia (2001), citing Bruch (1929) and Weber (1972), indicated larvae were found in the external accumulated debris of the nests of A. lundi and Acromyrmex lobicornis (Emery) in Argentina. Monné (1969) described the third instar from Trienta y Tres, Uruguay that was found in the nest of Acromyrmex species. Di Iorio (2014) noted that M. tigrina adults are essentially floricolous and have been collected from the flowers of Eryngium species (Apiaceae). Adult beetles were seldom found on other food sources, although they were observed feeding on slime fluxes, chewing the stem of Baccharis incisa Hooker and Arnott (Asteraceae), and collected in banana-baited traps (Di Iorio 2014). Burrowing owls, Speotyto cunicularia partridgei Olrog (Aves: Strigidae), feed on adults, and numerous beetle remains have been found in regurgitated pellets from owl nests (Di Iorio 2014).	en	Ratcliffe, Brett C.
