Sicoderus contiguous Vanin 1986: 589 . Holotype male (BMNH) from St. Vincent, examined. Anderson 1999: 135.

Description: Length male, 4.7–5.5 mm; length female 4.5–5.0 mm. Integument black, shining. Eyes separated by a distance about one-half width rostrum at midlength. Rostrum 1.13–1.15x length elytra in male; 1.25–1.32x 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 closely spaced, moderately large, elongate on disc, larger and deeper, forming weak striolae laterally on flanks; no setae present. Elytra in dorsal view widest at midlength, lateral margins convergent both anteriorly and posteriorly; humeri fully reduced, not at all angulate; no setae present. Strial punctures evident, small, shallow; striae not impressed. Membranous wings absent. Abdominal ventrite 1 of male in middle near posterior margin with two small raised patches of fine setosity; of female, uniformly convex in middle near posterior margin. Ventrite 5 narrowly slightly impressed medially in male, rounded in female. Legs with femora each with ventral margin with small tooth; tarsal claws lacking small basal tooth. Aedeagus (fig. 24) subequal in width throughout length, internal sac with pair of elongate thick basal sclerites subparallel, each with slight laterally directed basal extension. Female not dissected.

Material examined: ST. VINCENT: St. Andrew Parish, Vermont Nature Trail, 31.VIII.1991, C.W. & L. O’Brien (3 males, 1 female; CMNC, CWOB) . Charlotte Parish, La Soufriere Trail (east), 2.IX.1991, C.W. & L. O’Brien (2 females; CWOB). The type series from St. Vincent, West Indies (holotype, 2 male paratypes, 5 female paratypes; BMNH) was examined.

Comments: Vanin (1986) named this species from specimens taken from a number of unspecified sites on St. Vincent.
