Specimens examined.

Total of 124 specimens (85♀♀37♂♂ and 2 unsexed): Brunei (3♀♀), India (1♀), Japan (81♀♀37♂♂ and 2 unsexed).

Type series: LCT ♂ of Henicospilus pudibundae Uchida, 1928, Sapporo, Hokkaidô, JAPAN, 4.VI.1925, Tamanuki leg. (emerged from Dasychira pudibunda L.) (SEHU).

Distribution.

Eastern Palaearctic and Oriental regions ( Yu et al. 2016).

JAPAN: [ Hokkaidô] ( Uchida 1928; Shimizu 2020; present study); [ Tôhoku] Aomori*, Iwate*, Yamagata*, and Fukushima*; [Hokuriku] Niigata ( Shimizu 2020) and Ishikawa ( Togashi 2005); [ Kantô-Kôshin] Ibaraki*, Tochigi*, Gunma*, Nagano ( Chiu 1954; present study), Yamanashi*, Saitama*, and Tôkyô ( Uchida 1928; Shimizu 2020; present study); [ Tôkai] Shizuoka*, Gifu ( Chiu 1954), and Mie*; [Kinki] Kyôto *, Hyôgo ( Shimizu 2020), and Wakayama*; [ Chûgoku] Hiroshima ( Konishi and Nakamura 2002, 2005, 2010; Maeto and Shimizu 2019; Shimizu 2020; present study) and Yamaguchi ( Konishi and Nakamura 2002; present study); [Shikoku] Tokushima*, Ehime* and Kôchi *; [ Kyûshû] Fukuoka*, Nagasaki*, Miyazaki* and Kagoshima ( Fukuda and Kusigemati 1986; present study). *New records.

Bionomics.

Reared from Erebidae ( Lymantriinae ) in Japan: Calliteara pudibunda (L.) ( Uchida 1928, 1930) and Orgyia thyellina Butler ( Togashi 2005).

Differential diagnosis.

This species resembles E. biharensis , E. maruyamanus and E. transversus , all of which are rather difficult to distinguish from each other. However, E. pudibundae can be distinguished by the evenly curved fore wing vein 1m-cu&M (Fig. 36F ), lack of proximal pectinae of the hind tarsal claw, and entirely closely punctate meso- and metapleuron (Fig. 36E ).

Gauld and Mitchell (1981) separated E. biharensis , E. pudibundae and E. transversus by the value of CI, but with the caveat, "Whether this character will prove to be completely reliable we doubt". However, we consider these species to be certainly distinct when using a combination of characters (cf. Table 7 ).
