Description

Worker

Holotype. TL 3.3, HL 0.73, HW 0.58, CI 79, SL 0.45, SI 78, ML 0.45, ED 0.03, PW 0.41, AL 0.95, PL 0.30, PH 0.40, DPW 0.30, LPI 133, DPI 100.

Head nearly rectangular, longer than broad, lateral sides nearly parallel. Occipital margin straight, occipital corners bluntly prominent. Mandibles elongate, triangular, inner margin very short, about 1/3 length of masticatory margin. Masticatory margin with 4 teeth, including 1 basal tooth, 1 middle tooth, and 2 minute apical denticles beside the basal corner. Median lobe of clypeus protruding forward, nearly square, length : width = 3:4, lateral sides parallel, anterior margin straight. Longitudinal furrow between frontal lobes distinct. Antennae short, 12-segmented, apices of scapes reached to 4/5 of the distance from antennal sockets to occipital corners, antennal clubs 4-segmented. Eyes minute, with only 2 facets.

In profile view, promesonotum weakly convex, promesonotal suture and metanotal groove slightly depressed. Propodeal dorsum straight, about 2 times as long as declivity, posterodorsal corner rounded. Petiolar node very thick, roughly trapezoid, anterior face straight, dorsal face rounded into posterior face, anterodorsal corner bluntly prominent, posterodorsal corner indistinct. Subpetiolar process large, triangular, anteroventral corner bluntly prominent. Anterior and posteroventral faces nearly straight. In dorsal view, petiolar node trapezoid, widened backward, length : width = 1:1.1, anterior and lateral margins weakly convex, posterior margin weakly concave. Constriction between the two basal gastral segments distinct. Sting laterally compressed, apex relatively blunt.

Mandibles smooth and shining, with sparse fine punctures. Head, alitrunk, and petiole densely punctured, lateral sides of alitrunk finely longitudinally rugose, dorsal and posterior faces of petiolar node smooth. Gaster smooth and shining, dorsa of the two basal segments abundantly punctured, the rest segments sparsely punctured. Dorsa of head and body with sparse suberect short hairs and dense decumbent pubescence, gastral apex with abundant longer hairs. Scapes and tibiae with sparse suberect hairs and dense decumbent pubescence. Color brownish yellow, eyes black.

Type Material

Holotype: worker, CHINA: Tibet, Medog County, Medog Town, Yarang, 720m, forage on the ground in the secondary rain forest, 2008.V.20, Zheng-Hui Xu leg., No. A08-838.

Etymology
