The length of the workers is about 4 mm. The main color is reddish-brown (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) 0.80-0.85 mm; head width (HW) - 0.70-0.75 mm; the length of the scape of the antennae (SL) is 0.70-0.73 mm; the scapus index (SI) is 96-103. 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 1912 by the Swiss worldmecologist Auguste Trout under the original name Aenictus fergusoni var. breviceps Forel, 1912 , and its valid status was confirmed during a generic audit conducted in 2011 by Thai worldmecologist Dr. Weeyawat Jaitrong and Japanese entomologist S. Yamane S. based on material from working individuals from Borneo. It is included in the species group Aenictus laeviceps species group, where it is close to the species Aenictus rotundicollis , Aenictus sonchaengi , Aenictus laeviceps , differing in the presence of 2 to 4 hairs on the pronotum and only one pair of hairs on the frontal part of the head, stalk shape and partially sculpted breast (mesopleon, metapleurone, propodeum) [1] [2] .
