Description
Structures: Head (Figs. 1–3) smooth and polished, with large punctures on dorsum, genae, and posterolaterally of eyes. Frontal carinae short, hardly exceeding frontal fossae. Antennal scrobes and frontal lobes not developed; antennal insertion entirely exposed. Clypeus dorsally without median carina, ventrally with distinct central tooth; anterior margin with 7–8 small denticles in middle and two pairs of blunt teeth at sides. Labrum apically with pair of small tubercles. Mandibles (Fig. 2) smooth and shiny; masticatory margin of mandible with four teeth: strongest apical + second strongest (hardly shorter) preapical + long diastema + two small basal teeth of similar size; basal margin of mandible with slight dilatation at mid-length, but lacking distinct tooth. Palp formula 1, 3. Antennal scapes short, when lying on dorsum of head, slightly surpassing posterior margin of head. Eyes containing 11 ommatidia in longest row. Profile shape of mesosoma, petiole and postpetiole as in Figure 3. Dorsum of mesosoma slightly convex, smooth and polished except for a few scattered fine hair pits (Fig. 4). Pronotum with pair of relatively strong teeth; propodeum with pair of spines that are distinctly longer than pronotal teeth (Fig. 3). Mesopleural ridge almost straight, anteriorly not protruded into distinct tooth. Metapleural lobes subtriangular, acute. Petiole, postpetiole, and gaster smooth and shiny. Petiole in profile with moderately long peduncle, node without distinct angles. Postpetiole in profile rounded dorsally, in dorsal view broadening from front to back. Pilosity: Dorsal surfaces of head, mesosoma, petiolar node, and postpetiole with numerous, moderately long setae. First gastral tergite lacking erect or suberect setae. Clypeus with forward projecting setae between teeth and with four pairs of long setae at sides of medial part. Scapes and tibiae with numerous erect setae. Colour: Almost entirely black; clypeus, labrum, mandibles, antennae, and tarsi brown.
