Erodiscus delauneyi; Champion 1903: 272. O’Brien and Wibmer 1982: 100. Sicoderus delauneyi; Vanin 1986: 582. Anderson 1999: 135. Peck et al. 2014: 128.
Description:Length male, 3.9–4.9 mm; female, 3.4–7.0 mm. Integument black, shining. Eyes separated by a distance about equivalent to width of 2–3 ommatidia. Rostrum 0.91–0.96x length elytra in male; 1.02–1.25x length elytra in female. Antennal insertion at about apical 1/ 3 inmale, slightly beyond midlength in female. Prothorax constricted anteriorly, globose, widest at about middle; punctures widely spaced, very small, very shallow on disc and 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 with two small raised patches of fine setosity at distance from posterior margin of ventrite 1 by about length of ventrite 3; of female, uniformly convex in middle near posterior margin. Ventrite 5 impressed medially in male, margins of impression finely setose, rounded in female, not setose. Legs with front femora with ventral margin with small blunt tooth, middle and hind femora each with very small blunt tooth; tarsal claws with small basal tooth. Aedeagus (fig. 33) subequal in width throughout length, margins slightly sinuate, internal sac with pair of thick elongate basal sclerites subparallel, each widest towards apex and base, also with a pair of outwardly directed cone-shaped sclerites at about midlength. Female not dissected.

Comments:This species is very similar to S. lucidusfrom Dominicahowever the latter species lacks the small basal tooth on the tarsal claws and the setose patches on abdominal ventrite 1 are located much closer to the posterior margin of ventrite 1.
