Description
Worker
Akbar & Bharti (2015): Head globular in full face view, with posterior margin more or less rounded. Clypeus with a broad bilobed fork-like cuticular projection on its anterior-most part. Masticatory margin with 5-teeth. Eyes with 6-8 ommatidia in greatest diameter. Antennae 12-segmented with 3-segmented club. Mesosoma short and stubby, forming a continuous arch in profile;promesonotal suture not distinct in dorsal view. Metanotal groove indistinct. Propodeal declivity concave.Propodeum in lateral view with broad triangular spines, somewhat divergent in dorsal view. Petiole penduculate, with stocky petiolar node. In dorsal view, anterior face of petiolar node straight while posterior face slightly concave in the middle. Gaster rounded; truncated anteriorly.
Mandibles' dorsal face striate along entire length. Dorsum of head having confused network of striations. Underlying surface distinctly punctuate. Mesosoma, petiolar and postpetiolar nodes with irregular, widely spaced striations, which are more prominent along sides of pronotum and dorsal surface of petiole. Gaster with a fine matte appearance. Hairs on head and body erect, slightly broader in posterior half with sharp or blunt tips. Colour dark-brown, the antennae and legs slightly lighter.
