Description
Worker
Holotype. TL 11.5, HL 2.37, HW 2.23 , CI 94, SL 3.43, SI 154, PW 1.83, AL 4.75, ED 0.57. Head slightly longer than broad, almost round in full face view. Occipital margin moderately convex. Eyes prominent and highly behind midline of the head. Mandibles with 5 teeth. Clypeus with longitudinal central carina, its anterior border distinctly emarginated in the middle, with two small denticles laterally. Pronotum distinct convex, with two strong straight spines, long and point at front. Pronotal and mesonotal suture distinctly depressed; the mesonotal and propodeal suture blurring. Propodeal spines longer than pronotal spines, posteriorly pointed, and slightly curved downwards. In profile view, pronotum much higher than mesonotum and metanotum. Anterolateral of petiole with two small vertical tooth. Anterior surface and posterior surface of the petiolar node parallel in profile view, posterolateral armed with two long spines, pointing backwards the gaster and curved inwards in dorsal view, subpetiolar process distinct and digitiform. Legs long and thick. Gaster rounded.
Mandibles slightly longitudinally striate. Head, alitrunk and petiole closely and coarsely punctuate. Legs and gaster densely and finely punctuate. The whole body covered with sparse and recumbent pubescence. Erect hairs red-brown, very infrequent, only present on the clypeus, ventral and tail end of the gaster, decumbent hair present, sparse; head, thorax and petiole black, gaster dark-red.
Paratypes. TL 11.4~11.7, HL 2.33~2.70, HW 2.20~2.73, CI 91~99, SL 3.37~3.65, SI 128~154, PW 1.77~2.03, AL 3.70~4.35, ED 0.53~0.63 (12 individuals measured).
Type Material
Holotype worker, Tianjingshan Forestry Centre of Nanling Natural Reserve (24°41′N, 112°59′E), 450 m, Guangdong Province, collected on the path of the wildwood, 18-VIII-2007, No. 3, leg by Hou Zhan-hua; Paratypes: 12 workers, in the same nest, data as holotype but No.3-5. The type specimens are deposited in the Insect Collection, College of Life Science, Guangxi Normal University, Guilin, China.
