Diagnosis. As for the genus.

Redescription. TL = 5.0– 6.5 mm; EW = 4.0–5.0 mm. TL/EW = 1.3; PL/PW = 0.5; EL/EW = 1.0. Body ( Fig. 1a–c, e, f ) bicolored. In living specimens ( Fig 1e, f ) head black, pronotum with pronotal disc black and sides broadly brick red, scutellar shield black, elytra brick red with two black spots on each elytron: smaller adjacent to scutellar shield and second, much larger occupying apical half of elytron. Ventral side variable in coloration: mouthparts infuscate; antennae brick red, brick red with infuscate club or whole infuscate; hypomera brick red or infuscate; prosternum partially or whole infuscate; meso- and metasternum infuscate; meso- and metaepimera and meso- and metaepisterna partially or entirely infuscate; epipleura brick red; legs dark orange or with partially infuscate femora; abdomen brick red or with partially infuscate ventrite 1. In dried specimens, brick red color turns into dark red ( Fig. 1a–c ). Antennomere 3 as long as wide; antennomeres 4–8 transverse, antennal club consisting of three antennomeres; antennomeres 9–10 transverse, distinctly prominent laterally; terminal antennomere enlarged, truncate apically.

Male terminalia and genitalia ( Fig 4g –l ). Sternite IX ( Fig. 4g ) with base of apodeme membranous, apodeme rod-like, without additional sclerite at base of apodeme; tergite X short, transverse. Tegmen in inner view ( Fig. 4k ) with penis guide symmetrical, nearly parallel, tapering into rounded point, slightly recurved apically in lateral view ( Fig. 4l ). Parameres well developed, simple, about 1.4 x longer than penis guide, sparsely setose apically; tegminal strut broad, partially membranous. Penis capsule with outer and inner arms well developed ( Fig. 4h ); penis of equal diameter along entire length; tip swollen and partially membranous in lateral view ( Fig. 4i ), symmetrical in inner view ( Fig. 4j ).

Female genitalia ( Fig. 4m –o ). Spermatheca ( Fig. 4n ) vermiform, C-shaped, without clear nodulus and ramus; spermathecal accessory gland short, its opening placed at base of spermatheca; sperm duct short, shorter than spermatheca, its opening broadened, not sclerotized, connected laterally to spermatheca; infundibulum absent. Coxites broadly subtriangular, elongate ( Fig. 4m ), upturned and obliquely truncate on apices; styli reduced, bearing long setae in the middle of oval, membranous area ( Fig. 4o ). Proctiger longer than coxites, with hind edge rounded ( Fig. 4m ).

Distribution. Mexico, states: Aguascalientes, Guanajuato, Estado de México, Oaxaca, Querétaro, Veracruz.
