Sicoderus truncatipennis Vanin 1986: 594 View in CoL . Anderson 1999: 134. Perez-Gelabert 2008: 136. Holotype male (BMNH) from Port au Prince, Haiti, examined.

Description: Length male, 3.4–4.7 mm. Integument black, shining. Eyes narrowly separated by a distance of about 2 ommatidia. Rostrum 1.06–1.19x length elytra in male; 1.29–1.39x length elytra in female. 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. Aedeagus (fig. 84) subparallel-sided, internal sac with pair of elongate basal sclerites convergent apically, each with strong anterolateral projection at about midlength. Female not dissected.

Material examined: DOMINICAN REPUBLIC: Province Independencia, ESE Jimani, La Florida , 18°24’N 71°44’W, 20 m, moist site, 14.IV.1993, M.A. Ivie, D.S. Sikes, W. Lanier (2 males; CMNC) GoogleMaps . HAITI: mountains near Port au Prince, up to 2000’, 2.x.1934, P.J. Darlington Jr. (1 male, MCZC). The type series from Port au Prince , Haiti (holotype, 3 female paratypes; BMNH) was examined.

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). Vanin (1986) described this species from a series of five specimens collected from Haiti: Port au Prince, 20–22.III.1908, Dr. M. Cameron (BMNH).
