Sicoderus championi Vanin 1986: 593 . Holotype male (USNM) from Dominican Republic, Samana, examined. Anderson 1999: 134. Perez-Gelabert 2008: 136.

Description: Length male, 3.3–4.5 mm, female, 2.9–4.5 mm. Integument black, shining. Eyes narrowly separated by a distance of about 2–3 ommatidia. Rostrum 0.94–0.98x length elytra in male, 0.97–1.08x length elytra in female. Antennal insertion slightly beyond middle in male, at about middle in female. Prothorax constricted anteriorly, globose, widest at about middle; punctures various from widely spaced, small and deep dorsally on disc to large and deep, subcontiguous on disc and flanks, forming weak to distinct striolae; sparse erect setae present. Elytra in dorsal view widest at about midlength, lateral margins slightly convergent anteriorly and posteriorly; humeri present, weakly angulate; setae present, few. Strial punctures large, deep; striae not impressed throughout length. Membranous wings present. Abdominal ventrite 1 of male slightly to moderately raised in middle near posterior margin to small tubercle with small transverse patch of setosity at tip, of female, evenly convex. Ventrite 5 of male with median circular impression, of female evenly convex, not setose in either sex. Legs with all femora with inner margin with small blunt tooth; tarsal claws with small basal tooth. Aedeagus (fig. 23) subequal in width throughout length, internal sac with pair of elongate basal sclerites subparallel, variable in width, each with slight basal outwardly directed extension. Female not dissected.

Comments: An additional locality from Vanin (1986) is: Dominican Republic: Arroyo Hondo (near Ciudad Trujillo); this specimen was not examined. This species is very similar to S. perezi and was confused with the latter by me during early manuscript preparation. The rostrum is shorter in both sexes in S. championi and the basal sclerite of the internal sac is different (compare figs. 23 and 59). Vanin (1986) noted a similarity to S. tinamus , which has a less deeply and densely punctate pronotum and a different basal sclerite of the internal sac. Sicoderus championi exhibits some variation in the extent of punctation of the pronotum, especially dorsally on the disc which can vary from widely spaced and shallow to deep and subcontiguous, forming weak to distinct striolae.

This species appears to be common and widespread in low elevation or coastal areas throughout the Dominican Republic.
