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.

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.
