Measurements and indices.

Workers (n = 2): HL 0.68–0.69, HW 0.68–0.70, ML 0.65, PML 0.45–0.49, PW 0.65, SL 0.44, TL 2.79–2.84, CI 99–104, PMI 133–142, SI 63–64.

Diagnosis of worker.

Small species (HW 0.68–0.70 mm, TL 2.79–2.84 mm). Promesonotal shield shorter than broad and distinctly margined, broadly transparent at sides, overhanging lateral face of mesosoma; anterior corners of pronotum almost right angles; lateral margins of pronotum parallel, slightly sinuate. Petiole in profile tapered, the crest obliquely and narrowly truncate. Postpetiole nodiform, almost as long as high and roundly convex dorsal outline. Dorsa of head and promesonotal shield densely reticulate-rugulose; lateral portion of pronotum reticulate-rugulose; mesopleuron, metapleuron, and lateral faces of propodeum sparsely reticulate-rugulose, with smooth interspaces. Anterior face of petiole smooth and shiny, dorsum and lateral faces rugulose, posterior face smooth. First gastral tergite smooth, with an occasional faint shagreening around piliferous punctures.

The Thai specimens agreed well with the holotype ( CASENT 0902029) in structure, sculpturing, and pilosity. However, body color of the specimens collected from Thailand are reddish brown, while the holotype is paler, yellow (Fig. 1 View Figure 1 ). Reticulations on dorsum of head rather denser and smaller than that on the holotype (see Fig. 1 A, B View Figure 1 for comparison).

Distribution.

Thailand (Songkhla and Narathiwat, new record, Fig. 4 View Figure 4 ), Malaysia (West Malaysia, Sabah, Sarawak), Singapore, Indonesia (Java).

Habitat.

Two specimens from Narathiwat Province were collected from the ground in a disturbed area near a lowland evergreen forest, near the Thai – Malay border. A specimen ( THNHM - I- 00028943 , THNHM) from Songkhla Province was collected in a primary evergreen forest.
