Description: Length male, 3.9–6.2 mm, female, 4.0– 5.8 mm. Integument black, shining. Eyes narrowly separated by a distance of about 2–3 ommatidia. Rostrum 1.11–1.26x length elytra in male, 1.20–1.34x length elytra in female. Antennal insertion slightly beyond middle in male, at about middle in female. Prothorax constricted anteriorly, globose, widest slightly before middle; punctures closely spaced, large and deep, subcontiguous on disc and flanks forming distinct dorsal and lateral striolae; sparse erect setae present. Elytra in dorsal view widest at about midlength, lateral margins slightly convergent anteriorly and posteriorly; humeri present, weakly angulate; setae present, few. Strial punctures large, deep; striae not impressed throughout length. Membranous wings present. Abdominal ventrite 1 of male slightly raised in middle near posterior margin to small tubercle with small transverse patch of setosity at tip, of female, evenly convex. Ventrite 5 of male with median longitudinal finely setose impression, margins slightly raised and tufted with longer, fine setae at about midlength; of female tumid medially, not setose. Legs with all femora with inner margin with small tooth, tooth acute or blunt on front femur, very small, blunt on middle and hind femora; tarsal claws with small basal tooth. Aedeagus (fig. 59) widest at middle, internal sac with pair of elongate slightly sinistrally curved basal sclerites subparallel and two basal small patches of fine spicules. Female not dissected.

Derivation of species name: This species is named after Daniel E. Perez-Gelabert, a Dominican entomologist now at the United States National Museum in Washington, D.C. Dr. Perez-Gelabert has been working for a number of years compiling lists of the arthropods of Hispaniola.

Natural History: Adults have been collected in low elevation tropical thorn scrub.

Comments: This species is very similar to S. championi and was confused with this species by me during early manuscript preparation. The rostrum is longer in both sexes in S. perezi and the basal sclerite of the internal sac is different (compare figs. 23 and 59). It appears limited to Barahona and Pedernales provinces in the southern Dominican Republic.
