Antennal insertion slightly beyond middle in male, slightly before middle in female. Prothorax constricted anteriorly, globose, widest at about middle; punctures regularly closely spaced, moderately large and deep on disc and flanks forming striolae dorsally and laterally; sparse erect setae present or not. Elytra in dorsal view widest at about midlength, lateral margins convergent both anteriorly and posteriorly; humeri fully reduced; erect setae present. Strial punctures large, deep; striae slightly impressed throughout length. Membranous wings absent. Abdominal ventrite 1 of male slightly raised in middle near posterior margin to small transverse tubercle with small transverse patch of setosity at tip. Ventrite 5 of male with median circular impression with dense, fine setae laterally around impression. Legs with all femora with inner margin with small tooth, somewhat larger on front femora, smaller and more blunt on middle and hind femora; tarsal claws with small basal tooth.

Comments:
This species is unique among West Indian
Sicoderus
in the truncate apex of the elytra in lateral view. Described from
Haiti
, these are the first specimens recorded from
the Dominican
Republic. The description of the character states of females presented here is taken from
Vanin (1986)
.
