Description
Worker
holotype in parentheses: HW 0.96-0.98 (0.96); HL 1.00-1.05 (1.00); SL 1.07-1.09 (1.08); EL 0.19-0.20 (0.19); MSL 0.11-0.13 (0.11). SL/HL 1.03-1.08 (1.08); Number of ommatidia along long axis of eye ca.12.
Very similar to Brachyponera nigrita and Brachyponera batak. Mesopleuron usually with a transverse groove. Posterior faces of propodeum and petiole constantly punctate. Dorsum of mesosoma usually with more than ten standing hairs, some of which are longer than width of antennal segment 2. Gastral tergites 1 and 2 each with more than ten long standing hairs.
Queen
Similar to B. batak in body size and distinctly punctate metapleuron (in B. nigrita metapleuron almost smooth). Specimens from Malay Pen. tend to be larger than those from Borneo (HW: 0.83-0.91 vs. 1.04-1.06 mm). Mesosoma dorsally and gastral tergites with numerous long standing hairs.
Type Material
Holotype: worker, Ulu Gombak (ca. 250 m alt.), Selangor Prov., Malaysia., 5 vii 1999, F. Ito (FI99-291). Paratypes: 10w, 2q, from the same colony as holotype. The holotype is deposited in the Entomological Collection at Forest Research Institute, Kuala Lumpur, Malaysia, and paratypes in SKY Collection, Kagoshima University, Natural History Museum (SKY Collection), London (The Natural History Museum), Museum of Comparative Zoology, Harvard University (Museum of Comparative Zoology) and Natural History Museum of Los Angeles County (Los Angeles County Museum of Natural History).
Etymology
The name refers to the presence of numerous standing hairs on the dorsum of the bodies of the queen and worker.
