Henicospilus nigribasalis Uchida, 1928: 222; HT ♀ from Taiwan, SEHU, examined.

Specimens examined.

Total of 35 specimens (26♀♀9♂♂): India (5♀♀), Japan (14♀♀8♂♂), Sri Lanka (1♀), Taiwan (6♀♀1♂).

Type series: HT ♀ of Henicospilus nigribasalis Uchida, 1928, Baibara [= Meiyuan], TAIWAN, 25.VIII.1925, Kikuchi leg. (SEHU).

Distribution.

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

JAPAN: [ Kantô-Kôshin] Kanagawa ( Watanabe et al. 2016; present study); [ Tôkai] Shizuoka ( Konishi 1993; present study); [Kinki] Hyôgo *; [ Chûgoku] Shimane* and Hiroshima ( Konishi 1993; Konishi and Nakamura 2000; present study); [Shikoku] Ehime ( Konishi and Yamamoto 2000; Hisasue et al. 2015; present study) and Kôchi ( Konishi 1993; present study); [ Kyûshû] Fukuoka* and Kumamoto ( Konishi 1993; present study); [ Ryûkyûs] Okinawa ( Konishi 1993; present study). *New records. In Japan, it is restricted to the warmer Pacific coast and Ryûkyûs.

Bionomics.

No host records from Japan. Recorded as a parasitoid of Ericeia inangulata ( Guenée) ( Erebidae ) by Chiu et al. (1984) and Chen et al. (2009).

Differential diagnosis.

This species is very easily distinguishable from any other Enicospilus species on account of the characteristic colour pattern, especially of the metasoma and wings, as in Fig. 30A . Gauld and Mitchell (1981) suggested that E. nigribasalis is closely related to E. ashbyi and E. pallidus ; however, this species can easily be distinguished from them by colour pattern, shape of wing veins, and shape of the fore wing fenestra and sclerites.
