Terayama (2009) - The holotype was taken at the Berlese funnel in evergreen broad-leaved forest. A possible female individual is distinctly larger than A. silverstrii female (HL 1.20 mm, HW 1.15 mm, whereas ca. 0.90 mm and 0.75 mm in silvestrii female).
Identification
Terayama (2009) - This species resembles Stigmatomma silvestrii from Japan, Taiwan, Korea and China, and Stigmatomma octodentatum from China (Yunnan Province) but is easily separated from the latter two by the large body size (HL 1.15 mm, HW 1.10 mm, whereas ca. 0.85 mm and 0.70 mm in silvestrii worker and 0.93 mm and 0.80 mm in octodentatum worker, and the wide head with convex lateral margins, and the developed genal teeth.
