Zu and Zhang 2002 leptanillinae Fig 10-12.jpg

Holotype: TL 2.2, HL 0.47, HW 0.37, CI 79, SL 0.27, SI 73, PW 0.25, AL 0.63, ML 0.22, PNL 0.17, PNH 0.15, PNW 0.13, PPNL 0.13, PPNH 0.20, PPNW 0.13.

Head longer than broad, distinctly narrowed forward. In full face view, occipital margin weakly concave, occipital corners bluntly prominent, lateral sides roundly convex. Mandible narrow and slender, masticatory margin with 3 teeth. Clypeus protruding forward and bicarinated, anterior margin evenly concave. Antenna short, with 12 segments, apex of scape reached to 2/3 of the distance from antennal socket to occipital corner, segments 4-10 about as broad as long, antennal club indistinct. In profile view, pronotum evenly convex, promesonotal suture distinct. Mesothorax constricted at its anterior portion, mesonotum convex. Metanotal groove depressed. Propodeum weakly convex, about 2 times as long as declivity, posterodorsal corner rounded. In profile view, dorsum of petiolar node roundly convex, anterior face short and sloped, dorsal and posterior faces formed a single arch. Subpetiolar process very narrow, weakly convex, anteroventral corner acutely angled. In profile view, postpetiolar node shorter than petiolar node, with dorsum roundly convex, the sternite formed a large broad subpostpetiolar process with blunt anteroventrally pointed corner. In dorsal view, petiolar node longer than broad, lateral sides weakly convex. Postpetiolar node nearly square, lateral sides evenly convex, as broad as petiolar node. Mandibles, head and the whole body smooth and shining. Head and body with dense decumbent pubescence. Petiole, postpetiole and gaster with sparse subdecumbent hairs. Scapes and tibiae with dense decumbent pubescence. Body in color brownish yellow.

Paratype workers: TL 2.1-2.2, HL 0.47-0.50, HW 0.37-0.40, CI 76-80, SL 0.23-0.30, SI 64-77, PW 0.25-0.27, AL 0.57-0.63, ML 0.20-0.23, PNL 0.15-0.17, PNH 0.13-0.15, PNW 0.12-0.13, PPNL 0.13, PPNH 0.18-0.22, PPNW 0.12-0.13 (8 individuals measured). As holotype.
