Description: Length male, 4.4 mm. Integument black, shining. Eyes narrowly separated by a distance of about 2 to 3 ommatidia. Rostrum 0.97x length elytra in male. Antennal insertion slightly beyond middle in male. Prothorax constricted anteriorly, globose, widest at about middle; punctures dense, large and deep, subcontiguous, forming striolae on disc and laterally on flanks; sparse erect setae present near posterior margin. Elytra in dorsal view widest at about midlength, lateral margins subparallel anteriorly and posteriorly; humeri present, strongly angulate; setae present, few (perhaps abraded or broken). Strial punctures large, deep; striae very slightly impressed throughout length. Membranous wings present. Abdominal ventrite 1 of male slightly raised in middle near posterior margin to small tubercle with small patch of setosity at tip. Ventrite 5 of male with median circular impression towards apex. Legs with all femora with weakly developed small tooth; tarsal claws with small basal tooth. Aedeagus (fig. 46) distinctly widest at middle, internal sac with pair of very elongate basal sclerites subparallel, each slightly sinistrally curved, conjoined apically. Female not known.
Material examined: 1 male. Holotype male ( CMNC), labelled DOMINICAN REPUBLIC: Province Santiago Rodriguez, Sabaneta , Gurabo, 5.VII.1980, Abud-Mota.
Derivation of species name: This species is named ‘humeralis’ after the well-developed humeri, an uncommon feature in West Indian Sicoderus , where so many of the species are flightless.
Natural History: No details of biology are known.
Comments: The single male of this species known is very similar to S. championi ; however, in dorsal view the elytral humeri of S. humeralis are more pronounced with the elytra not noticeably inflated towards the middle and the form of the basal sclerite of the internal sac of the male genitalia is different (compare figs. 23 and 46).
