Known only from Fangchenggang City, Guangxi, China.

Identification

Chen et al. (2019) - China: Similar to Anochetus rufus, but well separated from the latter by the following characters: sides of pronotum smooth and shining; metanotal groove widely depressed; junction of propodeal dorsum and declivity forming a pair of small lateral teeth; the constriction between AIII and AIV with short ridges. Also similar to Anochetus agilis, but well separated from the latter by the following characters: mesonotum smooth and shining; junction of propodeal dorsum and declivity forming a pair of small lateral teeth; petiolar node narrowly pointed at apex; the constriction between AIII and AIV with short ridges; body yellowish brown.

In full-face view head longer than broad, posterior margin strongly concave. Mandibles linear, gradually broadened apically; inner margin without denticles, apical portion with three distinct teeth. Anterior margin of clypeus gently concave. Antennae 12-segmented; scapes long, surpassing to posterior corners of head by about 1/7 of its length. Maximum diameter of eye wider than apical width of mandible. In lateral view mesosoma slender, pronotum weakly convex. Promesonotal suture narrowly weakly notched. Mesonotum short and sloping posteriorly. Mesonotum groove widely depressed. Propodeal dorsum weakly concave, posterolateral corners of propodeum forming a pair of small teeth. Petiole triangular and stout, anterior margin slightly concave, posterior margin convex, anterior margin longer than posterior margin, dorsal apex acutely angulate; subpetiolar process developed, subtriangular. Frons with striae running in a fan shape, remainder of head smooth and shining. Mesosoma smooth and shining, pronotum with transverse striae on pronotal neck, dorsa of mesonotum and propodeum transversely striate. Petiolar node smooth and shiny except lower half area faintly striate. Gaster smooth and shining. Dorsum of body with scattered erect hairs; mandibles with abundant subdecumbent pubescence; scapes and tibiae with sparse suberect hairs and dense decumbent pubescence.
