( Figures 31–32 , 36 . Map 4) http://zoobank.org/urn:lsid:zoobank.org:act:F9A3172C-0244-486D-8D38-566CC3261F79 Description: Length male, 2.8–3.9 mm ; female, 2.5–3.8 mm . Integument black, shining. Eyes rather widely separated by a distance about two-thirds width rostrum at midlength. Rostrum 1.24–1.50x length elytra in male; 1.35–1.61x length elytra in female. Antennal insertion at about apical 2/ 5 in male, slightly before midlength in female. Prothorax constricted anteriorly, globose, widest at about middle; punctures widely spaced, very small, very shallow on disc, larger and deeper, forming striolae laterally on flanks; scattered erect setae present, especially along anterior margin. Elytra in dorsal view widest at midlength, lateral margins convergent both anteriorly and posteriorly; humeri fully reduced, not at all angulate; a few long, fine setae present. Strial punctures evident, very small, very shallow; striae not impressed. Membranous wings absent. Abdominal ventrite 1 of male with conical tubercle near posterior margin with a small patch of setosity at tip; of female, uniformly convex in middle near posterior margin. Ventrite 5 slightly impressed at middle with sparse setae laterally around impression, uniformly convex in female, not setose. Legs with all femora simple, ventral margin lacking tooth; tarsal claws with small basal tooth. Aedeagus (fig. 36) subequal in width throughout length, internal sac with pair of elongate basal sclerites convergent apically, but separate, each with elongate subparallel basal extension. Female not dissected. FIGURES 29–32. Species of Sicoderus . 29. Sicoderus franzi , dorsal habitus. 30. Sicoderus franzi , lateral habitus. 31. Sicoderus guanyangi , dorsal habitus. 32.

Derivation of species name: This species is named after Guanyang Zhang, presently at the Florida Museum of Natural History, University of Florida , formerly at Arizona State University, Tempe, Arizona where he studied weevils of the subfamily Entiminae (and Heteroptera). He was also a field companion on the 2013 Cuba field trip. Natural History: This species has been collected in tropical evergreen forest ( 1000–1100 m ) and in cloud forest ( 1515 m ). Comments: This species is very similar to S. turnbowi , S. ramosi and S. bautistai , but can be distinguished by the shape of the basal sclerite in the male aedeagus, the lack of femoral teeth and the conical tubercle of abdominal ventrite 1 of males.
