Common Name
Language: Japanese

This species has been found in grasslands, the margins of forests and within forests. Nests are under stones as well as in leaf litter and directly in soil. It is a trophophoretic species, associated with the mealybug Eumyrmococcus smithii, a trophobiont (Lapolla, 2004). Nuptial flights have been observed from late March to June with alate females leaving the parent nest with a gravid female Eumyrmococcus in her mandibles (Uye, 1928, 1933; Teranishi, 1929; Terayama, 1988).


LaPolla (2004) - Worker: 11 segmented antennae; mesosomal dorsum flat with many short erect hairs; pronotum short, rises very steeply toward mesonotum; mandible with 3-4 teeth. Queen: As in worker with modifications expected for caste. Male: 12 segmented antennae; digiti 2.5 times longer than cuspi, with peg-like teeth along sides. Compare with Acropyga lauta.

The worker of this species is fairly easily recognized, with 3-4 teeth and no diastema separating the basal teeth from the other teeth. A. sauteri is currently placed in the myops species-group. The long digiti, similar shaped parameres and dark color of the male suggest a close relationship with Acropyga myops.
