Female genitalia ( Fig. 8 ). Epigynum with Y-shaped margin ( Fig. 7 ), ducts il-shaped curve.

Type specimens. Holotype: ♂, Kami-kamo, Kita-ku, Kyoto City , Kyoto Prefecture, 3-V -1983, T. Kamura leg. , allotype: ♀, same data as for the holotype . Paratype: ♂, Fujioka City , Gunma Prefecture, 26-V -1985, T. Hayashi leg .

Notes. This new species resembles A. montana Hayashi, 1986 , but is distinguished from the latter by the shapes of retorolateral apophysis on palpal tibia and copulatory ducts. This new species is smaller than A. coreana and A. montana , and its body length is less than 2.5 mm.

Etymology. This species is named after the collector, Dr. T. Kamura.
