Description
Worker
Holotype. TL 2.4, HL 0.66, HW 0.52, CI 79, ML 0.31, MI 47, SL 0.36, SI 69, PW 0.28, AL 0.66. Preapical tooth small, located upon the concave section of the apical quarter of the inner mandibular margin; angle that marks commencement of concave section of margin is proximal to preapical denticle. Anterior clypeal margin broadly shallowly concave. Preocular impression in anteroventral margin of head small and very shallow, amounting to hardly more than a weak constriction. In full-face view dorsolateral margin of head with 3-4 very short stubby projecting hairs, anteriormost just behind level of eye rather than apicoscrobal; hairs directed more dorsally than laterally. With head in profile cephalic dorsum with about 6 pairs of short simple erect hairs (actual number difficult to ascertain as head much ecrusted); anteriormost hair is approximately at level of posterior margin of eye. Pronotal humeral hair absent, standing hairs absent from dorsum of pronotum; a single pair of short erect hairs present on mesonotum. Hairs on first gastral tergite simple and blunt, apparently restricted to base and apex (sclerite between these may have lost its hairs as medially located hairs are present in the other species of the group). Petiole node as long as broad in dorsal view. Reticulate-punctate sculpture on disc of postpetiole evenly dense across entire disc, not partially effaced medially. Basigastral costulae shorter than disc of postpetiole.
Type Material
Holotype worker, Philippines: Quezon, San Jose, Bukidnon, 28.xii.1984, in nest sample of Pheidole sp. (C. K. Starr) (The Natural History Museum).
