Diagnosis. Medium sized (TL: 4.8–5.4 mm), oblong oval species. Dorsal surface black, pronotal sides, elytra laterally from dorsal stria 4, and apex of elytra yellow (Fig. 7). All six dorsal striae on elytra complete, well impressed; submarginal stria rather long, starting at about elytral midlength and terminates in approximately apical fifth of elytral length. Females with numerous short strioles covering basal two thirds of elytral length, except for base and lateral margin (Fig. 8). Median lobe sickle-shaped in lateral view, in apical fourth gradually narrowing to obtusely pointed apex (Fig. 25). Parameres 'D'-shaped; apex short and broad; apical lobes long, club-shaped (Fig. 26).

Collecting circumstances. The species was found in a shallow, ephemeral water body.

Distribution. India; Ghosh & Nilsson (2012) listed the species from Assam, Bihar, Delhi, Jharkhand, Manipur, Tripura and Uttar Pradesh. We add records from Maharashtra (Satara District) (Fig. 45).
