Description
Worker
Holotype. TL 4.2, HL 0.82, HW 0.72, CI 87, SL 0.60, SI 83, PW 0.50, AL 1.25, ED 0.20 (0.28 ×HW) and with 10 ommatidia in the longest row. Head longer than broad, sides feebly convex, median occipital margin weekly convex, occipital corners rounded. Mandibles and their teeth are as in diagnosis of the genus. Eyes moderate large, situated slightly in front of the midlength of the sides of the head. Faint vestiges of frontal carinae present, extending back from the posterior extremities of the frontal lobes to beyond the level of the posterior margins of the eyes. Subocular groove complete, running from the mandibular insertion to the anteroventral margin of the eye, then passing through a shallow angle and continuing along the sides to the later occipital margin, where the subocular groove ends slightly concave. Antennal scape relatively long (SI 83). Eyes relatively large (0.28 × HW) with 10 ommatidia in the longest row. Alitrunk elongate and low in profile, mesonotum unarmed. In dorsal view, sides of mesonotum slightly convex; metanotal groove shallow but distinct. In profile, propodeal spines long and slightly curved down at tip, about 1.3 times as long as the distance between their bases. Legs relatively long, maximum length of hind femur (0.72 mm) as long as head width.
In dorsal view, petiolar node distinctly longer than wide and sides of the node almost straight, dorsal face of the node moderately convex, petiolar spiracle at the midlength of the peduncle, dorsal face of postpetiolar node roundly convex. First gastral tergite smooth, except for a band of short basigastral costulae feebly present immediately behind the post petiole, the spaces between the basigastral costulae smooth. Head, alitrunk, petiole and postpetiole reticulate-rugose. Propodeal declivity with 3 fine transverse rugulae between the spines and remaining portion smooth and shining. Gaster smooth. Erect or suberect hairs densely present on dorsal surface head and whole body. Colour yellowish-brown, gaster dark brown, darker than head and alitrunk.
