Stictoponera meghalaya

This species has been collected from forest litter.

Identification
Lattke (2004) - This species is similar to Gnamptogenys binghamii from the western part of its geographic range and is sympatric with it in the Garo Hills of the Indian state of Meghalaya. G. binghamii has distinct occipital lobes, and the lateral cephalic margins are relatively parallel in frontal view and are not diverging posterad as in G. meghalaya. The frons of G. binghamii has striae on the transverse ridges between the foveolae, while the ridges in G. meghalaya are mostly glazed or rounded. G. meghalaya is also slightly smaller than G. binghamii on average.

Petiolar node evenly convex in lateral view, ventral process subquadrate; postpetiolar dorsum foveolate-punctate with shallow undulations and slight scalloping, foveolae denser, more ovaloid on sides; sternum posterolaterally foevolate, medially mostly smooth with median strigulose strip; dorsum of abdominal segment 4 mostly smooth with abundant punctae, punctae deeper laterally, posterior margin with narrow band of longitudinal strigulae. Fore coxa transversely strigulose in lateral view; fore tarsus opposite strigil with single stout seta; metacoxal tooth elongate and triangular. Dorsum of thorax and abdominal segments 1-4 with scattered erect to subdecumbent hairs. Head, mesosoma, petiole, and gaster dark brown; mandibles, antennae, legs ferruginous.
