Description
Translated from the original description:

Length 3-3,2 mm. Head and thorax red, petiole, abdomen and appendixes dark yellow. Very smooth and shiny, except for the posterior two-thirds of the side of the thorax, which are matt, shagreened. Pilosity yellowish, not dense but very long, over the head and body. General aspect slender and convex, similar to Aenictus of the group eugenii-congolensis-mariae, but petiole and antennae are clearly distinct:

Antennae relatively thin. Second funicular segment length almost double than first and more than double of third. Thorax rather convex, sides of mesothorax and propodeum with strong longitudinal striae. In eugenii, petiolar segments angled in its dorsal face, shagreened or puntuated, both with a ventral anterior tooth and a posterior peduncule, cylindrical and puntuated. Villiersi with dorsal and ventral profile rounded, without teeth. The peduncule is striated, but the rest of petiole and postpetiole smooth. This type of petiole resembles A. mariae, austral species known from Cameroon, with the head smaller and the funicle shorter. A. mentu seems to belong to this group, from Imatong Mountains, with the petiole lower and slender
