Description: Length male, 3.4 mm. Integument black, shining. Eyes separated by a distance about one-half width rostrum at midlength. Rostrum 0.85x length elytra in male. Antennal insertion at about apical 2/ 5 in male. Prothorax constricted anteriorly, globose, widest at about middle; punctures closely spaced, moderate, shallow 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 at about midlength with two small, raised patches of fine setosity. Ventrite 5 impressed medially in apical two-thirds. Legs with all femora with ventral margin of each with very small blunt tooth; tarsal claws lacking small basal tooth. Aedeagus (fig. 92) widest in basal one-half, apical one-half distinctly narrowed, internal sac with pair of elongate basal sclerites sinistrally strongly L-shaped. Female not known.

Material examined: 1 male. Holotype male ( CWOB), labelled GRENADA: Grand Etang National Park , Mt. Qua Qua Trail, 10.IX.1991, C.W. & L. O’Brien.

Derivation of species name: This species is named after Robert Woodruff (retired) of Gainesville, Florida in recognition of his extensive collecting efforts on Grenada and other West Indian islands .

Comments: This species is distinctive in having the setose patches on abdominal ventrite 1 located at about the midlength of the ventrite and not at the posterior margin, a feature shared only with S. delauneyi from Guadeloupe.
