Mesosoma. Lateral area of pronotum largely smooth ventral 0.3. Epicnemial carina present laterally.

Mesopleural fovea smooth. Anterior transverse carina of propodeum complete on lateral section. Posterior transverse carina of propodeum complete. Lateral longitudinal carina of propodeum usually partly weakly present by weak ridge, or absent. Lateromedian longitudinal carina of propodeum usually indistinct except for basal section, sometimes median section restricted by weak ridge. Fore wing length 7.0–9.0 mm, with vein 2 m-cu with two bullae. Hind wing with Cu 1 present, nebulous. Fore coxa without ridge ( Fig. 4 F).

Metasoma punctate, shiny by strong reflection ( Fig. 1 E, 7 E). Punctures on T1 to basal 0.5 of T4 slightly longitudinally striated by coalescent punctures. T1 1.6–1.8 times as long as maximum wide, its median dorsal carina nearly completely present, short median longitudinal keel sometimes present posteriorly ( Fig. 6 E). T2 1.0– 1.1 times as long as maximum width ( Fig. 6 E, 7 E). T2 and T3 with short median longitudinal keel less than basal 0.5 (latter somewhat indistinct) ( Fig. 6 E).

Distribution ( Fig. 12 ). Japan (Hokkaido, Honshu, Sado Is.*, Shikoku* and Kyushu*).

Biology. The following hosts are recorded in Japan: Pandemis heparana (Denis & Schiffermüller) ( Momoi, 1978) , Homonopsis illotana (Kennel) and Acleris sp. ( Nakaya, 2009).

Remarks. This species closely resembles A. bipunctoria and A. evanescens , but it can be distinguished by the characters shown in the Remarks of A. bipunctoria and A. evanescens .
