Description

Worker

Holotype. Major. HL 0.50 mm; HW 0.40 mm; SL 0.23 mm; CI 80; SI 58; WL 0.43 mm; PL 0.18 mm; PH 0.13 mm; DPW 0.08 mm; TL 1.3 mm.

Head 1.3 x as long as wide, with parallel sides and weakly convex posterior margin in frontal view; vertex with a pair of small tubercles. Mandibles with 5 teeth. Antennae with 9 segments; scape short, 0.5 x head length; 2nd segment longer than wide; 3rd to 7th segments each wider than long; 8th segment slightly longer than wide; 9th segment 2.8 x as long as wide. Eyes small, each consisting of 2 facets only. Ocelli absent.

Alitrunk as in Fig.; dorsum of promesonotum broadly convex in lateral view; metanotal groove deeply incised dorsally; mesopleura without transverse groove; anterior half of propodeal dorsum strongly convex and posterior half almost straight. Posterior margins of propodeum with a thin lamella; posterodorsal comers of propodeum angulated, not forming a spine.

Petiole longer than high, with convex dorsal margin; subpetiolar process forming an acute anteroventral tooth. Postpetiole slightly higher than long, with convex dorsal margin in lateral view.

Head very weakly microreticulate; genae with many longitudinal striae; promesonotum smooth and shining; mesopleura and propodeum microreticulate; waist weakly microreticulate; gaster smooth.

Body yellowish brown.

Paratype minors. HL 0.31-0.33 mm; HW 0.28-0.29 mm; SL 0.23 mm; CI 88-90; SI 78-82; WL 0.42-0.43 mm; PL 0.11 mm; PH 0.09 mm; DPW 0.06 mm; TL 0.9-1.0 mm (n = 5).

Head square, with subparallel sides and weakly concave posterior margin in frontal view. Mandibles with 5 teeth. Eyes small, consisting of a single facet only. Antennae with 9 segments; 3rd to 7th segments each wider than long; 8th segment as long as wide; apical segment 2.4x as long as wide.

Promesonotal dorsum broadly convex in lateral view; metanotal groove strongly incised dorsally; propodeal dorsum weakly convex; posterior margins of propodeum with a thin lamella; its dorsalmost part obscurely angulated. Petiole longer than high, with convex dorsal margin in lateral view; subpetiolar process fornting an acute anteroventral tooth. Postpetiole longer than high, with broadly convex dorsal margin in lateral view.

Head smooth with shallow punctures sparsely; pronotum smooth and shining; mesopleura and propodeum microreticulate; waist microreticulate excepting disc of postpetiole smooth; gaster smooth and subopaque.

Body yellowish brown.
