Differential diagnosis. Sulabanus mamasensis belongs to the S. mamasensis group as characterized above and its elytra have a yellow patch on the humeral third of elytra similar to those of S. minor and S. cordatus . It can be recognized by the shape of the male genitalia with the slightly widened middle part which gradually narrows to the parallel–sided apical part of phallus (Fig. 15, compare with Figs. 19 and 21). Additionally, S. mamasensis has the smallest eyes in the group of species which are similar in colouration and belong to the S. mamasensis group.

Description. Body dark brown to black, only elytra with bright yellow transverse patch at humeral third of elytra, legs light brown. Head partly hidden by pronotum, frontal distance between eyes 1.57 times eye diameter. Pronotum flat, 1.1 times wider that long. Elytra parallel–sided, 3.75 times longer than width at humeri. Male genitalia widened in middle part, apical third relatively slender, apex asymmetrical (Figs. 15– 16).

Measurements. BL 7.1 mm, HW 1.59 mm, PL 0.91 mm, PW 1.01 mm, Ediam 0.35 mm, Edist 0.55 mm, EL 6.0 mm.

Distribution. Sulawesi, known only from the type locality in the Mamasa valley in southwestern Sulawesi.

Etymology. The specific epithet is derived from the name of the type locality.
