Description: Length male, 5.5 mm; female, 6.1 mm. Integument black, shining with somewhat greenish-brown reflection. Eyes rather widely separated by a distance about two-thirds width rostrum at midlength. Rostrum 1.11x length elytra in male; 1.41x length elytra in female. Antennal insertion slightly beyond midlength in male, at about midlength in female. Prothorax constricted anteriorly, globose, widest at about middle; punctures widely spaced, very small, very shallow on disc and laterally on flanks; no setae present. Elytra in dorsal view widest at about midlength, lateral margins convergent both anteriorly and posteriorly; humeri fully reduced, not at all angulate; no setae present. Strial punctures evident, very small, very shallow; striae not impressed. Membranous wings absent. Abdominal ventrite 1 of male near posterior margin with two small patches of fine setosity; of female, uniformly convex in middle near posterior margin. Ventrite 5 impressed medially in male, uniformly convex in female. Legs with front femora with small tooth on ventral margin, middle and hind femora simple, lacking tooth; tarsal claws with small basal tooth. Aedeagus (fig. 9) widest at apex, internal sac with pair of basal sclerites subparallel, slightly hooked at base. Female not dissected.

Material examined: 1 male, 1 female. Holotype male ( CWOB), labelled HAITI: Department du Sud, Formond , 1650m, 28.i.1984, S.R. Yocum, beating bamboo and ferns. Paratype. Data as holotype (1 female; CWOB) .

Derivation of species name: This species is named ‘aeneus’ after the greenish-brown metallic reflection of the cuticle.

Natural History: Two specimens were collected beating bamboo and ferns at 1650m elevation.

Comments: This species is similar to S. striatolateralis and S. pseudostriatolateralis in the very fine punctation of the pronotum, but unlike those two species the posterolateral pronotal flange is not microstriate.
