Sicoderus hirsutiventris Anderson 1999: 131 . Holotype male ( CWOB) from St. Thomas , Virgin Islands, examined in 1999.

Description: Length male, 4.3–6.5 mm. Integument black, shining. Eyes separated by a distance about one-half

width rostrum at midlength. Rostrum 0.80–0.85x length elytra in male. Antennal insertion at apical two-fifths in male. Prothorax constricted anteriorly, globose, widest at anterior one-third; punctures well-separated, very sparse, very fine and shallow on disk, slightly deeper and larger in anterior one-quarter and slightly deeper on flanks; with scattered, appressed setae along anterior constriction. Elytra in dorsal view distinctly widest at midlength, lateral margins convergent both anteriorly and posteriorly; humeri fully reduced, not at all angulate; with isolated, erect but short (perhaps abraded or broken), scattered setae. Strial punctures evident, shallow, moderately fine; striae not impressed throughout length. Membranous wings present, slightly shorter than elytra in length. Abdominal ventrite 1 of male raised in middle near apical margin forming a markedly elevated tubercle with two small subcontiguous patches of setosity at tip. Ventrite 5 of male with large rounded deep, densely setose impression almost as large as entire ventrite 5. Legs with front femora with small, blunt ventral tooth; middle and hind femora lacking tooth; tarsal claws with small basal tooth. Aedeagus (fig. 45) widest at about middle, internal sac with group of elongate curved sclerites at about basal 2/3 of length. Female not known.

Material examined: VIRGIN ISLANDS: St. John Est. , Gt. Cinnamon Bay, Cinnamon Bay Trail, 17 July 1994, M.S. Becker, beating (male paratype, WIBF).
