Description: Length male, 3.6 mm; female, 4.0– 4.5 mm. Integument black, shining. Eyes moderately separated by a distance about one-half width rostrum at midlength. Rostrum 1.02x length elytra in male; 1.06–1.12x length elytra in female. Antennal insertion at about apical 1/ 3 in male, at about apical 2/ 5 in female. Prothorax constricted anteriorly, globose, widest at about middle; punctures moderately dense, regularly spaced, very fine and shallow on disc and laterally on flanks; erect setae absent; posterolateral flange (extended over base of elytra) with dense microstriae. Elytra in dorsal view widest at about midlength, lateral margins convergent both anteriorly and posteriorly; humeri fully reduced, not at all angulate; scattered erect fine setae present. Strial punctures evident, small, shallow; striae not impressed. Membranous wings absent. Abdominal ventrite 1 of male in middle near posterior margin with two closely spaced small patches of setosity; of female, uniformly convex in middle near posterior margin. Ventrite 5 of male flattened medially towards apex, not setose; of female, uniformly convex. Legs with all femora lacking tooth; tarsal claws with small basal tooth. Aedeagus (fig. 60) widest at apex, internal sac with pair of elongate basal sclerites sinistrally strongly L-shaped. Female not dissected.

Derivation of species name: This species is named ‘pseudostriatolateralis’ after its similarlity to S. striatolateralis as a second species with the distinctive microstriate lateral pronotal flange.

Natural History: Adults have been collected beating vegetation from forests between 1150 and 1850 m elevation.

Comments: This species is very similar to S. striatolateralis but the latter has a blunt tooth on the front femora, few if any elytral setae and different male genitalia.
