Ponera menglana

The type material was collected from a soil sample in seasonal rain forest and two ground samples, with one of the latter from a karst monsoon forest.

Identification
This new species is close to Ponera sinensis, but with body larger, HL 0.65-0.68, HW 0.58-0.60. In profile view posterodorsal corner of petiolar node more convex. Posteroventral corner of subpetiolar process only with a minute denticle.(Xu 2001)

Distribution
This taxon was described from China.

Anterior margin of clypeus evenly convex. Apex of scape reached to 9/10 of the distance from antennal socket to occipital corner, antennal club consisted of the apical 5 segments. Eye with one facet. In profile view dorsum of alitrunk slightly convex, promesonotal suture distinct, metanotal groove very weak with fine visible trace. Dorsum of propodeum about as long as declivity, posterodorsal corner of propodeum rounded, lateral sides of propodeum weakly depressed, declivity obviously. depressed, lateral sides of declivity distinctly marginate. In profile view petiolar node higher than long, anterior face straight and vertical, dorsal and posterior faces formed a single arched surface, anterodorsal corner blunt. Subpetiolar process with small circular fenestra, anteroventral corner obliquely truncate, posteroventral corner with a minute denticle. In dorsal view petiolar node roughly semicircular, anterior and lateral borders formed a single arch, posterior face weakly concave. Gaster distinctly constricted between the two basal segments. Mandibles smooth and shining. Head, alitrunk and the two basal segments of gaster densely and finely punctured. Petiole with anterior and lateral faces weakly finely punctured,. posterior face smooth. Segments 3 - 6 of gaster smooth and shining. The whole body surface with sparse erect or suberect hairs and dense decumbent pubescence. Scapes and tibiae with dense decumbent pubescence, but without erect hairs. Body in.color black. Mandibles, antennae, legs, subpetiolar process and apex of gaster yellowish brown.
