Type series: HT ♂ of Henicospilus pseudoconspersae Sonan, 1927, Taihoku, TAIWAN, 25.IV.1927, J. Sonan leg. (TARI); HT ♀ of Henicospilus mushanus Uchida, 1928, Musha, TAIWAN, 24.VII.1925, Matsumura (SEHU); HT ♀ of Enicospilus tenuinubeculus Chiu, 1954, Fukien, Shaown, CHINA, 23-29.V.1944, H.F. Chao leg. (TARI).

Distribution.

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

JAPAN: [ Kantô-Kôshin] Saitama*; [ Tôkai] Shizuoka*; [Kinki] Hyôgo *; [ Chûgoku] Shimane* and Hiroshima ( Maeto and Shimizu 2019; present study); [Shikoku] Tokushima* and Kôchi *; [ Kyûshû] Kumamoto* and Kagoshima*; [ Ryûkyûs] Kagoshima* and Okinawa ( Sonan 1940; Shimizu 2020; present study). *New records.

Bionomics.

No host records from Japan. Described as a parasitoid of Arna pseudoconspersa Strand ( Erebidae ) ( Sonan 1944; Gauld and Mitchell 1981; Chen et al. 2009) and recorded as a parasitoid of Lymantriinae ( Erebidae ) in China by He et al. (2004).

Differential diagnosis.

This species can be very easily distinguished from all other Enicospilus species by its characteristic sclerites of the fore wing fenestra (i.e., proximal sclerite entirely weakly pigmented and half-moon-shaped, and margin of the proximal sclerite distinctly separated from the margin of the fenestra, as in Fig. 34F ).

This species exhibits a wide range of morphological variation in size and colour pattern. The proximal sclerite is usually weakly pigmented but is strongly pigmented in the holotype of E. tenuinubeculus .
