Description

Worker

Holotype: TL 4.9, HL 1.10, HW 0.80, CI 80, SL 0. 83, SI 104, PW 0.63, AL 1.47, ED 0.10, ML 0.80, MI 80, PNL 0. 37, PNW 0. 53. Head longer than broad, lateral sides slightly convex, occipital margin roundly depressed, occipital corners bluntly protruding. Clypeus with longitudinal central carena, anterior margin extruding into a blunt dent in the middle. Mandibles long and narrow, inner margin with 5 long teeth, apical tooth slender and curved. Eyes small, in full face view placed on the lateral margins, close to bases of mandibles. Antennal scapes just reach to occipital corners. In profile view, dorsum of alitrunk weakly convex, lowering down backward. Promesonotal suture distinct , metanotal groove disappear. Dorsum of propodeum very weakly convex, nearly straight; declivity obliquely truncate, shorter than dorsum. Petiolar node thick, in profile view rectangular, anterior and posterior faces slightly convex, dorsal face roundly convex; subpetiolar process rectangular, with a subtransparent oblique slit, anteroventral angle obliquely truncate, posteroventral angle blunt. Gaster conical, apical half curved downward. Sting long and strong. Mandibles smooth and shining. Head and gaster with moderately dense uniform large punctures, distance between two punctures shorter than diameter of a puncture. Dorsum of alitrunk and petiolar node finely and densely punctate, lateral sides of alitrunk with sparse large punctures and microrugae. Dorsum of head, antennae, and legs with abundant depressed pubescences , without hairs. Dorsa of occiput, alitrunk, petiolar node, and gaster with abundant suberect short hairs and rich depressed pubescences. Body in colour black; mandibles, antennae, legs, and apex of gaster reddish brown.

Queen

Paratype dealate: TL 5.1, HL 1.03, HW 0.83, CI 81, SL 0.83, SI 100, PW 0.70, AL 1.60, ED 0.17, ML 0.87, MI 84, PNL 0.37, PNW 0.53 (n=1).

Similar to holotype, but body larger; eyes larger, with 3 ocelli; occipital margin weakly depressed; alitrunk with tegulae, mesopleuron with an oblique furrow; head, pronotum, and gaster dark reddish brown.
