Description: Length: 8 mm; length of fore-body: 4.1 mm. Body black, shiny; mouthparts, antennae and legs testaceous (fore-body Fig. 4 ). Head transverse (1 x 1.2), the eyes very large and prominent, the temples short with well marked postero-lateral angles ( Fig. 4h ); surface with numerous irregularly scattered large and small punctures leaving a narrow impunctate area on vertex and two other broader ones posteriorly. Pronotum as long as broad (1.3 mm). widest at anterior 1/3 rd, the sides retracted posteriorly, the postero-lateral angles broadly rounded; discal series of 6 large irregularly spaced punctures. Elytra sub-quadrate, as long as broad (1.4 mm); each elytron with five series of numerous, closely spaced punctures, the interstriae with a few randomly disposed other punctures; the interstria beween series IV and V, and sides just beyond series V with numerous much smaller punctures, albeit larger than the small punctures of pronotum, the interstices devoid of microsculpture. Abdominal tergites with sparse small asperate punctures.

Male: sternite VII unmodified; emargination of sternite VIII shaped like those of related species, extending to about 6/16 ths the length of sternite; aedoeagus: Figs 4 al, 4av.

This new species is very distinctive among members of the Nigerrima group due to the dense double puncturation of fore-body, with relatively large diameter of the secondary punctures.
