Re-description. Size: Total length (without labrum) 6.3 mm- 7.6 mm (mean= 6.8 mm, n=7). Head: Shining greenish black. Mandibles yellowish, brownish distally in females, teeth brownish marginally. Labrum (male Fig. 372 , female Fig. 373 ) barely longer than wide, yellowish, with six apical teeth (five teeth in one male) and one lateral tooth. Labial and maxillary palpi yellowish. Antennae lanceolate, extending posteriorally behind elytral shoulders in males, slightly shorter in females, scape with a single apical bristle, antennomeres 2 to 5 glabrous, antennomeres 6 to 11 finely and evenly pubescent; scape yellowish above, black on underside, all the other antennal segments brownish. Clypeus glabrous. Frons smooth with two shallow bumps in the posterior part of the orbital plates. Thorax: Pronotum shining greenish black, barely longer than wide, barely more constricted in front than at back in males, evenly constricted in females, transverse furrows strong, middle line and lateral lines nearly obsolete, middle line with several transverse short branches. Elytra: Shining brownish black, with basal and apical humps, distinctly punctate in front, shallower towards apex ( Fig. 367 ). Apex rounded with a little sutural tooth. Maculation composed of a brownish yellow humeral lunule, brownish yellow basal dot, short yellow central band, and light yellow apex which reaches the apical humps ( Figs. 368-370 ). The humeral lunule is connected with the basal dot at the base. Ventral aspect: Venter brownish. Legs brownish yellow, meso-and metafemora somewhat darker in the apical half. Aedeagus: ( Fig. 371 ) curved, tip elongated and bent, total length 1.6 mm.

Distribution. India (? West Bengal, Assam, Arunachal Pradesh).
