Major. Holotype measures HW 2.22, HL 2.49 (CI 90), SL 0.97 (SI 44), EL 0.22, HFL 1.16 (FLI 47; FWI 19) mm. Foveae on head numerous (even in vicinity of clypeus), very tiny and shallow (except for larger foveae along borders of antennal scrobes and beneath head, where foveae become confluent). Head virtually lacking pilosity. Cephalic hollow present but not as conspicuous as in A. mindanao. A darkly pigmented streak extends to hollow from dorsum of head; wide medial sulcus conspicuous from hollow to frontal area. Clypeal index 174. Forward margin of clypeus lacking a medial projection. Hypostomal teeth present.

Propodeal spines short, with distinctly thickened bases; bent caudad. Pronotal angle drawn out into a distinct tooth. Node of petiole without distinct dorsolateral denticles or spines, PWI narrow to intermediate (ca. 64). Anterior peduncle of petiole long and narrow, and lacking both lateral and sublateral petiolar hairs; subpetiolar declivity lacking. Postpetiole subrectangular, similar to that of A. mindanao; with only two pairs of hairs dorsally. Femora with scattered hairs, and with ventral surfaces distinctly concave. Orange yellow, with legs yellowish orange; head a richer orange and with contrasting yellow antennae.

Type Material

Holotype. Major worker deposited in Museum of Comparative Zoology from Malaysia: Sarawak: Mount Poi, 200 ft. (E. Mjoberg).
