| Anochetus risii|
Brown (1978) – Ferruginous yellow in color, with pale yellow legs; the pronotum is striate or rugulose in front and around the sides of the disc, but the center of the disc is smooth and shining. In A. risii and related species, the dorsal inner margin of the mandible is nearly straight and is edentate with a smooth margin, the preapical angle tends to be acute and is directed somewhat apicad as well as mesad, and the intercalary tooth of the apical trio is reduced and situated far out on the ventral apical tooth near its apex, which may thus appear furcate in young specimens. In older specimens, the intercalary tooth may be worn to a nub, or broken off, and scarcely detectable. A representative worker from Kusang, China has HL 1.62, HW 1.44, ML 1.19, scape L 1.58, eye L 0.28 mm; CI 89, MI 73.
