The length of the workers is about 4 mm. The main color is tan (legs and antennae are lighter). Head, breast ( pronotum , except mesonotum and propodeum ), stalk ( petiol and postpetiol) and abdomen shiny. The body is covered with long spaced hairs. Workers head length (HL) 0.73-0.78 mm; head width (HW) - 0.63-0.68 mm; the length of the scape of the antenna (SL) is 0.60-0.68 mm; the scapus index (SI) is 92-100. Antennae 10-segmented, long scape , reaching posterior margin of head. The mandibles are subtriangular. The anterior margin of the clypeus is convex, with several denticles. The stalk between the breast and the abdomen in workers consists of two segments, and in females and males - of one ( petiol ). The mandibular palps of females and workers are 2-segmented, the lower labial palps composed of 2 segments (formula 2.2; in males 2.1). The propodeal spiracle is located in the upper lateral part of the posterior thorax. Shins with two spurs. The sting is developed. The species was first described in 2011 by the Thai worldmecologist Dr. Weeyawat Jaitrong and the Japanese entomologist S. Yamane S. based on material from working individuals from Sumatra. It is included in the species group Aenictus laeviceps species group, where Aenictus hodgsoni is close to the species, differing in partially sculpted breasts (mesopleuron, metapleuron, propodeum) and few chest hairs (less than 10), as well as in species Aenictus fulvus and Aenictus alticola , differing in the sculpted part chest (mesopleuron) and the shape of the stalk [1] .
