Type locality. Mexico, Guerrero
Type data. Two card mounted male syntypes with the following labels were examined: 1) male, Type [circular label with red margin], Amula, Guerrero, 6000 ft., Sept., H. H. Smith; BCA coll. IV. 3., Attelabus heterocerus Sharp ; Attelabus heterocerus , male type D. S. Mexico, Smith. 2) male, Chilpancingo, Guerrero, 4,600 ft., July, H. H. Smith [on card with specimen]; BCA coll. IV.3., Attelabus heterocerus Sharp [upside down]; Sharp Coll. 1905313; Attelabus heterocerus Ind. Camp. D.S. The male from Amula is here designated as the lectotype.
Type holder. British Museum of Natural History ( BMNH)
Size range. Male 4.4 x 2.2 mm to 6.1 x 3.4 mm; Female 6.3 x 2.4 mm (one female only)
Description. Body black to brownishblack with orangishred humeri. Head longer than wide, without punctures; frons concave, with weak median ridge; eyes reniform, moderately protuberant. Rostrum shorter than head, robustly enlarged beyond antennal insertions, width at apex nearly three times as wide as frons, dorsally beyond antennal insertions with moderately to densely punctured; punctures small; postlabial area in male with two short widely separated divergent blunt tipped spinelike projections. Antennae inserted near basal 1/4 of rostrum; club elongatecompact, subequal to funicle in length in male; basal and middle club segments long, subequal in length; terminal segment much shorter; funicular segment 1 ovoglobose, shorter than scape; segments 23 slightly longer, clavate, subequal in length; segment 4 same as 2–3 but shorter; segments 57 moniliform; segment 7 more robust than 5 and 6. Pronotum smooth, shiny, with minute punctures; lateral base with strigae and larger punctures; anterior collar weakly defined, dorsally widened and more or less vshaped. Scutellum 1/3 wider than long, 4 sided, posterior margin broadly rounded. Elytra short, about as long as wide, widest at humeri; in dorsal view slightly narrowed from humeri to elytral apices, with weak transverse depression behind scutellum; humeri simple, rounded, moderately protuberant; striae small, widely spaced, becoming smaller and less distinct posteriorly; intervals, flat, smooth, wide, with numerous minute punctures. Profemora evenly swollen in both sexes.
Distribution ( Fig. 3 View FIGURES 1 – 8 ). Most specimens examined, including Sharp’s type, are from the Mexican state of Guerrero. Specimens have also been taken in the Mexican states of Mexico and Colima.
Comments. This is the only species of Omolabus with a blackish body and large orangishred humeral maculae (Figs. 49–52). The color pattern is like that of the North American Attelabus bipustulatus (Fabr.) but O. heterocerus has larger size and the male profemora are unarmed.
Host plants. Host plant association for this species is unknown.
