Worker
Jaitrong and Yamane (2011) - Measurements. Worker lectotype and paralectotype (n = 2): TL 3.95– 4.00 mm; HL 0.85–0.88 mm; HW 0.78 mm; SL 0.73–0.75 mm; ML 1.38–1.43 mm; PL 0.33 mm; CI 89–91; SI 94–97.

Lectotype and paralectotype - Head in full-face view slightly longer than broad, with sides and posterior margin feebly convex; occipital margin bearing a carina. Antennal scape relatively short and thin, not reaching the posterolateral corner of head; antennal segments II–X each longer than broad; II slightly longer than each of III–VII. Frontal carina short, slightly extending beyond the posterior margin of torulus. Anterior margin of clypeus convex, bearing several denticles. Masticatory margin of mandible with a large apical tooth followed by a medium-sized subapical tooth, 4 denticles, and a medium-sized basal tooth; basal margin lacking denticles. Mesosoma relatively slender; promesonotum in profile convex dorsally and sloping gradually to metanotal groove; dorsal outline of propodeum almost straight; area between propodeal spiracle and metanotal gland bulla impressed; propodeal junction rounded; declivity feebly concave, not margined dorsally and laterally. Petiole relatively short, almost as long as high; its node in dorsal outline strongly convex; subpetiolar process weakly developed, triangular, apex directed downward and forward; postpetiole almost as long as petiole. Entire head including antennal scape smooth and shiny. Mandible very finely striate except along masticatory margin. Mesosoma entirely smooth and shiny, except for metapleuron and metanotal groove that have irregular longitudinal rugae; propodeal dorsum with about 3–5 short longitudinal rugae. Petiole and postpetiole entirely smooth and shiny. Legs entirely smooth and shiny.

Head and mesosoma dorsally with relatively sparse standing hairs mixed with sparse short hairs over the surface; longest pronotal hair 0.20 mm long. Entire body reddish-brown. Typhlatta spot located anterior to occipital corner.

Type Material
Jaitrong and Yamane (2011) - Two syntype workers from Philippines, Luzon, Ilocos Norte Prov., Bangui (, examined). One worker is selected as the lectotype, the other as paralectotype.
