Holotype. TL 4.4, HL 0.90, HW 0.62, CI 69, SL 0.40, SI 65, PW 0.43, AL 1.17, EL 0.30, REL 33, PDH 0.40, MTW 0.35, PDI 114, PL 0.63, PH 0.26, DPW 0 .23, PLI 42, PWI 37. Head roughly rectangular, distinctly longer than broad. In full face view, occipital margin short and relatively straight, occipital corners rounded. Anterior 21.3 of lateral side weakly concave. Mandible narrow and slender, with 3 teeth on the masticatory margin and 1 denticle on basal margin. Median lobe of clypeus narrow and protruding, ·anterolateral corners furnished with a pair of elongate teeth appears fork-like, anterior margin between the teeth straight. Apex of scape reached to 3/5 of the distance from antenna] socket to occipital corner. Eyes large and surpassed lateral sides of head. Ocelli absent. In profile view, pronotum slightly convex, lateral borders distinctly marginate. Mesonotum straight and slope down backward. Metanotal groove widely and deeply impressed. Anterior face of propodeum short and sloped, dorsum slightly convex and slope down backward, posterodorsal corner rounded, declivity straight and slightly longer than dorsum. In dorsal view, pronotum narrowed backward, humeral corners roundly prominent. Metanotum raised up as a small conical prominence between the spiracles. In posterior view, pronotum weakly convex, laterodorsal corners sharp and rightly angled. In profile view, anterior peduncle of petiole slender and weakly curved down, ventral face weakly concave, petiolar node roundly convex with anterodorsal corner a little higher. Postpetiolar node slightly lower than petiolar node.
Mandibles sparsely, finely and longitudinally striate. Head, pronotum and mesonotum very sparsely and finely punctate, interspace smooth. Mesopleuron, metapleuron and lateral sides of propodeum weakly, finely and longitudinally rugulose. Metanotal groove with short longitudinal ridges. Petiole, postpetiole and gaster smooth. Dorsum of anterior peduncle of petiole densely and finely punctate. The whole body with sparse decumbent pubescences, standing hairs very sparse: 2 pairs on frontal carinae, 1 pair on vertex, 2 pairs on pronotum, 1 pair on petiole and 1 pair on postpetiole. Mesonotum and propodeum lack standing hairs. Gaster with sparse erect hairs. Scapes and tibiae with abundant pubescences, but lack standing hairs. Body color black. Mandibles and clypeus reddish brown. Mesofemora, metafemora and petiole blackish brown. Antennae, tibiae and tarsi yellow. Pro femora, mesocoxae, metacoxae and postpetiole yellowish brown.
