The types were collected from a soil sample in monsoon forest.

Identification

Xu & Liu (2012) - This new species is close to Myopias conicara but apices of scapes fail to reach occipital corners; posterolateral margins of petiolar node without an oblique furrow, in dorsal view petiolar node broader than long; in profile view subpetiolar process thick, ventral face distinctly convex after the anteroventral tooth.

Description

Worker

Holotype. TL 5.9, HL 1.25, HW 1.15, CI 92, SL 0.93, SI 80, ML 1.00, ED 0.18, PW 0.88, AL 1.83, PL 0.60, PH 0.83, DPW 0.68, LPI 138, DPI 113.

Head nearly square, slightly longer than broad, weakly narrowed forward. In full face view, occipital margin slightly concave, occipital corners rounded, lateral sides weakly convex. Mandibles slender and linear, inner margin weakly convex, masticatory margin about 1.3 times as long as inner margin, basal tooth blunt. The basal 1/2 of masticatory margin concave, the apical 1/2 obliquely truncated. Median lobe of clypeus protruding and widened forward, trapezoidal, without longitudinal central carina, length : width = 1:1.8, anterior margin weakly concave. Longitudinal furrow between frontal lobes distinct. Antennae 12-segmented, apices of scapes reached to 9/10 of the distance from antennal sockets to occipital corners, antennal clubs 4-segmented. Eyes relatively large, with 11-12 facets in the maximum diameter. In profile view, anterior 1/2 ventral face of head longitudinally convex, anteroventral corner bluntly angled.

In profile view, dorsum of alitrunk weakly convex, promesonotal suture and metanotal groove weakly depressed. Dorsum of propodeum about as long as declivity, posterodorsal corner rounded, declivity weakly longitudinally depressed. Petiolar node nearly square, anterior face straight, dorsal and posterior faces slightly convex, anterodorsal corner bluntly prominent, posterodorsal corner roundly prominent. Subpetiolar process complex, roughly cuneiform, anteroventral corner acutely toothed, ventral face evenly convex behind the tooth, posteroventral corner toothed. In dorsal view, petiolar node trapezoid and widened backward, length : width = 1:1.3, anterior and lateral margins weakly convex, anterolateral corners rounded, posterior margin straight. Constriction between the two basal gastral segments distinct. Sting laterally compressed, apex relatively blunt.

Mandibles smooth, with sparse punctures. Head smooth, dorsum with abundant punctures, vertex, occiput, and ventral face with sparse punctures. Alitrunk smooth, with sparse large punctures, lateral sides of mesothorax, metathorax, and propodeum with fine longitudinal striations. Propodeal declivity smooth, the lower portion transversely striate. Petiole smooth, with sparse large punctures, lateral sides finely longitudinally rugose. Gaster smooth, first segment and basal portion of second segment with abundant large punctures.

Dorsum of head with sparse suberect hairs and dense decumbent pubespubescence. Dorsum of body with abundant suberect hairs and abundant decumbent pubescence. Anterior face of petiolar node with dense pubescence. Scapes and tibiae with sparse subdecumbent hairs and dense decumbent pubescence. Color brownish black. Mandibles, antennae, legs, and gastral apex reddish brown.

Paratype. TL 6.1, HL 1.30, HW 1.20, CI 92, SL 0.93, SI 77, ML 1.05, ED 0.20, PW 0.88, AL 1.80, PL 0.63, PH 0.88, DPW 0.73, LPI 140, DPI 116 (1 individual observed). As holotype.

Type Material

Holotype: worker, CHINA: Yunnan Province, Hekou County, Nanxi Town, Laodoutian, 750m, collected from a soil sample in the monsoon forest, 2010.IV.5, Hui-Qin Zhu leg., No. A10-2557. Paratype: 1 worker, with same data as holotype.

Etymology

The new species is named after the Chinese minority nationality Hani who commonly lives in southern Yunnan Province.
