Watanabe, Kyohei, 2022, Revision of the genus Alloplasta Förster, 1869 (Hymenoptera, Ichneumonidae Banchinae) from Japan, Zootaxa 5188 (1), pp. 55-73 : 56-57

Genus Alloplasta Förster, 1869

Alloplasta Förster, 1869: 167 .

Type species: Lissonota murina Gravenhorst, 1829 (= Ichneumon piceator Thunberg, 1824 )

Asymmictus Förster, 1869: 200 .

Type species: Asymmictus iridescens Davis, 1897 (= Meniscus superbus Provancher, 1874 ). Designated by Viereck (1914). Synonymized by Townes (1970).

Trysicampe Förster, 1869: 207 .

Type species: Ichneumon piceator Thunberg, 1824 . Designated by Perkins (1962).

Trichopimpla Cameron, 1903: 303 .

Type species: Trichopimpla pilosa Cameron, 1903 .

Diagnosis. See Townes (1970). In Eastern Palearctic genera of Atrophini , this genus can be separated from similar genera with a short ovipositor by the hind wing with nervellus intercepted near or anterior to the middle ( Figs 1 A–C ).

Distribution. Holarctic, Oriental and Neotropical regions ( Yu et al. 2016).

Remarks. The tarsal claws of all Japanese species show the sexual dimorphism, i.e., nearly entirely pectinate in females and almost simple, with a few basal pectens in males.

Japanese species can be distinguished by the following key. For some species males are unknown, thus no key for males is established.
