Description: Length male, 4.9 mm. Integument black, shining. Eyes rather widely separated by a distance about two-thirds width rostrum at midlength. Rostrum 1.00x length elytra in male. Antennal insertion at about apical 2/ 5 in male. Prothorax constricted anteriorly, globose, widest at about middle; punctures widely spaced, small, shallow on disc, slightly larger and deeper, forming vague striolae laterally on flanks; erect setae absent. Elytra in dorsal view widest at about midlength, lateral margins convergent both anteriorly and posteriorly; humeri fully reduced, not at all angulate; erect setae absent. Strial punctures evident, small, shallow; striae not impressed. Membranous wings absent. Abdominal ventrite 1 of male flat medially, setose patches lacking. Ventrite 5 flattened at middle, not setose. Legs with all femora simple, ventral margin lacking tooth, anterior face of swollen area of hind femur longitudinally striate; tarsal claws with small basal tooth. Aedeagus (fig. 82) widest at base, internal sac with structure not visible (due to excessive KOH clearing; also likely responsible for short temones and overall lack of sclerotization). Female not known.
Material examined: 1 male. Holotype male ( CWOB), labelled HAITI: Department Sud-Oueste , Parc National La Visite, Morne la Visite, 2100m, 12.V.1984, M.C. Thomas.
Derivation of species name: This species is named after Michael C. Thomas (retired), a coleopterist at the Florida State Collection of Arthropods in Gainesville, Florida and who collected this and other Haitian weevils.
Natural History: The single known specimen was collected at 2100m elevation.
Comments: This distinctive species has an elytra that is more elongate-narrow than in other Sicoderus species and has the swollen area of the hind femora longitudinally striate. The holotype specimen had been previously dissected and the aedeagus cleared beyond a point allowing for recognition of internal structure.
