Distribution (Fig. 11). Japan (Hokkaido, Honshu, Sado is.*, Shikoku*, Kyushu*, Yakushima Is.*). This species is widely distributed in the Palearctic Region (Yu et al., 2012).
Biology. The following hosts are recorded in Japan: Pandemis heparana (Denis & Schiffermüller) (Momoi, 1963) and Pandemis cinnamomeana (Treitschke) (Nakaya, 2009; present study).
Remarks. This species resembles A. honmai in slender body with blue reflection but it can be easily distinguished from the latter by the epicnemial carina absent laterally (present in A. honmai), the metasomal tergite almost smooth (weakly punctate in A. honmai) and yellow area of pronotum restricted as small spot before tegula (Fig. 2 C) (yellow band along upper margin in A. honmai: Fig. 2 D). This species, A. bipunctoria, A. honmai and A. stena are sometimes collected at same place and thus they are sometimes confused.
