Description: Length male, 2.8–3.3 mm; female, 3.6–4.0 mm. Integument black, shining. Eyes rather widely separated by a distance slightly less than width rostrum at midlength. Rostrum 1.06–1.09x length elytra in male; 1.08–1.11x length elytra in female. Antennal insertion slightly before middle in male and female. Prothorax constricted anteriorly, globose, widest at about anterior one-third; punctures well-separated, sparse, very fine and shallow on disk, not much deeper or larger in anterior one-quarter or 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; with scattered, very fine erect setae. Strial punctures evident, shallow, moderately fine; striae not impressed. Membranous wings absent. Abdominal ventrite 1 of male flat basally, in middle near posterior margin with two very small setose points, not tuberculate; of female, uniformly convex in middle near posterior margin. Ventrite 5 of male flattened medially towards apex; of female, uniformly convex. Legs with all femora simple, ventral margin lacking any trace of tooth; tarsal claws simple, no basal tooth. Aedeagus (fig. 12) subparallel-sided, internal sac with pair of elongate sinuate basal sclerites, convergent but separate anteriorly, and basal patch of dense, fine spicules. Female not dissected.

Derivation of species name: This species is named after Ross Beaty of British Columbia, Canada in recognition of his financial investment in the research programs of the Canadian Museum of Nature.

Natural History: Adults were collected in pluviselva (term used in Cuba for a montane wet forest) and dry cloud forest litter (958–1370 m) and beating vegetation along trails.

Comments: In contrast to all other members of the genus from the Greater Antilles, this species, S. bipunctivenris , S. caladeler and S. morio all lack a small basal tooth on the tarsal claws. With the exception of S. lucidus from Dominica, all of the species from the Lesser Antilles lack the basal tooth on the tarsal claws as well.
