Holotype worker: TL 4.6, HL 1.00, HW 0.67, CI 67, SL 1.03, SI 155, PW 0.60, AL 1.57, ED 0.17, ML 0.50, PL 0.50, PH 0.60, DPW 0.40, LPI 120, DPI 80.
Head roughly rectangular, distinctly longer than broad. Occipital margin straight, occipital carina obvious. Occipital corners rounded. Anterior 2/3 of lateral sides of head relatively straight, posterior 113 narrowed backward. Mandibles slender, inner margin without tooth, masticatory margin with only 1 apical tooth, basal corner rounded. Clypeus with sharp longitudinal central carina, median lobe extruding at apex. Scape of antenna surpassed occipital corner by about 1/3 of its length. Segments of flagellum longer than broad, the second and third joints about equal. In profile view dorsum of alitrunk deeply depressed at metanotal groove. Promesonotum evenly convex, promesonotal suture distinct. Dorsum of propodeum slightly convex, about 3 times as long as declivity, declivity weakly convex. In profile view petiolar node trapezoid , lowering down forward, anterior face nearly straight, about 112 as high as posterior face, anterodorsal angle rounded, posterodorsal angle bluntly extruding, dorsal face evenly convex, posterior face straight. In dorsal view the node as broad as long, narrowed forward. Subpetiolar process small, nearly square, posteroventral corner dentiform. Constriction between the two basal gastral segments distinct. Mandibles and clypeus longitudinally striate. Head, alitrunk and petiole densely punctate. Lateral sides of pronotum smooth. Lateral sides of mesonotum and metanotum longitudinally rugose. Gaster smooth and shining. Dorsum of head and body with abundant erect long hairs, suberect short hairs and decumbent pubescence. Dorsum of head with dense pubescence. Scapes , femora and tibiae with abundant subdecumbent hairs and dense decumbent pubescence. Head, alitrunk and petiole brownish black. Gaster blackish brown. Mandibles, antennae, clypeus and legs reddish brown.
