Description: Length male, 3.2–3.8 mm; female, 2.9–3.8 mm. Integument black, shining. Eyes separated by a distance of about one half width of rostrum at midlength. Rostrum 1.00–1.08x length elytra in male, 1.09–1.17x length elytra in female. Antennal insertion slightly beyond middle in male, at about middle in female. Prothorax constricted anteriorly, globose, widest at middle; punctures sparse, moderately large and deep, well-separated, not forming striolae on disc but with vague striolae laterally on flanks; scattered erect setae present. Elytra in dorsal view widest at about midlength, lateral margins convergent anteriorly and posteriorly; humeri fully reduced, not at all angulate; numerous erect setae present. Strial punctures large, shallow; striae very slightly impressed throughout length. Membranous wings absent. Abdominal ventrite 1 of male not raised in middle near posterior margin but with small tuft of fine setosity; of female, uniformly convex in middle near posterior margin. Ventrite 5 of male with shallow, finely setose, median impression extended about one-half length of ventrite 5; of female, uniformly convex. Legs with front femora with very small, blunt tooth, middle and hind femora lacking tooth; tarsal claws with small basal tooth. Aedeagus (fig. 11) widest at apex, internal sac with pair of elongate curved basal sclerites, strongly convergent and conjoined anteriorly, each lacking basal extension. Female not dissected.

Derivation of species name: This species is named after José Antonio Bautista, a Dominican professional baseball right fielder formerly for the Toronto Blue Jays of Major League Baseball.

Natural History: Two specimens were collected beating vegetation in secondary pine/guava forest (1160 m).

Comments: Along with S. ramosi , S. guanyangi and S. turnbowi , these four species form a complex of closely related species distinguished by the form of the basal sclerite of the internal sac of the male genitalia, form of the male ventrite 1 and presence and size of femoral teeth.
