MATERIAL. China: Hainan, Jianfengling Natural Reserve , 18°44.854'N, 108°55.761'E, 641 m, 9.IV 2016, 1 worker and 1 female, leg. Zhilin Chen (No. G 160941) GoogleMaps .
DESCRIPTION. Worker ( Figs 1 – 3 View Figs 1–6 ). TL 4.19, HL 0.72, HW 0.59, CI 82, SL 0.41, SI 69, PW 0.44, MSL 1.13, PL 0.56, PH 0.34, DPW 0.25, LPI 61, DPI 45. (1 individual measured). In full-face view head rectangular, distinctly longer than broad, the middle of posterior margin slightly concave, posterior corner rounded, lateral margin slightly convex. Preoccipital carina distinct, almost encircling the posterior margin of the head. Mandible slender, masticatory margin with a bluntly apical tooth and a trapezoidal lobe; inner margin with three inconspicuous teeth. Anteriorly margin of clypeus weakly concave, posteriorly margin with distinctly continuous carina. In dorsal view, outer face of labrum with much more peg-like denticles. Frontal lobe absent. Antennal socket completely exposed. Antenna 12-jointed, scape stout, apices of scape reached to 2/3 of the distance from antennal socket to occipital corner. Eye and ocellus absent.
In lateral view mesosoma slender. Promesonotal suture impressed. Metanotal groove distinct. Dorsum of pronotum slightly convex; dorsum of mesonotum and propodeum almost straight and slightly lower than pronotum. Propodeal declivity weakly concave, posterodorsal corner rounded. Petiolar node oval shaped, much longer than high, anterior margin steep, posterior margin short, and unconspicuous, anterodorsal and posterodorsal corner rounded, dorsal margin weakly convex, anterior 2/3 of ventral margin much convex, posterior 1/3 of ventral margin converged. Subpetiolar process distinct, anteroventral coner broadly rounded, posteroventral coner bluntly toothed. Gaster very long, abdominal segment III longer than broad, Segment IV with differentiated presternite. Sting long and strong.
In dorsal view pronotum longer than broad, sides of pronotum slightly convex, remaining portion of mesosoma slightly narrower than pronotum and almost parallel-sided. Petiole much longer than broad, posterior slightly narrowed. Gaster long spindle-shaped, segment VI and VII laterally compressed.
Whole body brown, antennae and legs light brown. Body surface moderately smooth and shining. Head with scattered superficially piligerous punctate; mandible with sparse large punctures; mesosoma sculptured more weakly than head; petiole and gaster almost smooth and shining. Head with densely erect or suberect short hairs; anterior margin of clypeus and outer margin of mandible with relatively long and sparse erect hairs; antennal scape with sparse erect hairs and denser pubescence; mesosoma, petiole and gaster with sparser standing hairs.
Female ( Figs 4 – 6 View Figs 1–6 ). TL 5.72, HL 0.91, HW 0.72, CI 79, SL 0.47, SI 65, ED 0.16,PW 0.59, MSL 1.19, PL 0.75, PH 0.31, DPW 0.41, LPI 41, DPI 55. (1 individual measured). Head with morphological characters similar to the worker, but female lateral margin almost parallel. Inner margin of Mandible teeth conspicuous. Eye large, situated slightly in front of midpoint of lateral margin. With 3 ocelli. In profile view, alitrunk stranger than the worker, dorsum moderately convex. In dorsal view, mesonotum fusiform, with a pair of parallelly shallow furrow on side portion. Mesoscutum oval. Metanotum crescent, narrow and transverse. Petiole and gaster similar to the worker, except for the subpetiolar process of female broadly rounded, without any tooth.
Sculptures, hairs and pubescences similar to the worker. Color also similar to the worker, but the head of female dark brown, the space between the 3 ocelli black.
DISTRIBUTION. Vietnam, China (new record).
NOTES. This species was only described on the base of two workers. Here we provide the description of female but so far the male of this species is unknown.
