Description: Length male, 4.9–5.5 mm; female, 4.2–4.4 mm. Integument black, shining. Eyes separated by a distance about one-half width rostrum at midlength. Rostrum 1.28–1.32x length elytra in male; 1.27–1.37x length elytra in female. Antennal insertion at about apical 2/ 5 in male, at about midlength in female. Prothorax constricted anteriorly, globose, widest anterior to middle; punctures widely spaced, very small, very shallow on disc, slightly larger and deeper laterally on flanks, not forming striolae; no erect setae present. Basal margin of pronotum angulate laterally, dorsal and lateral faces interrupted by an acute angulation, dorsal face flat and with a row of 4 or 5 linearly arranged larger punctures across width. 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 slightly impressed. Membranous wings absent. Abdominal ventrite 1 of male slightly raised in middle near posterior margin with a small patch of setosity at tip; of female, uniformly convex in middle near posterior margin. Ventrite 5 flat at middle in male, uniformly convex in female, not setose in either sex. Legs with all femora simple, ventral margin lacking any trace of tooth; tarsal claws with very small basal tooth. Aedeagus (fig. 35) widest towards apex, internal sac with pair of elongate basal sclerites hooked basally. Female not dissected.

Derivation of species name: This species is named after Nico M. Franz, professor of entomology at Arizona State University, Tempe, AZ where he works on the systematics and evolution of weevils. He was formerly a professor at the University of Puerto Rico in Mayagüez and also a field companion on the 2012 Cuba trip.

Natural History: Specimens were collected beating.

Comments: This is one of two species of Sicoderus known from Puerto Rico, the other being S. ivieorum .
