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.

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.
