Eniscospilus (sic) dasychirae Cameron, 1905a: 123; HT ♀ from Sri Lanka, NHMUK, examined.

Eniscospilus (sic) horsfieldi Cameron, 1905a: 124; HT ♀ from Sri Lanka, NHMUK, examined; synonymised by Townes et al. (1961: 273).

Henicospilus borneensis Szépligeti, 1906: 138; HT ♀ from Borneo, TM, not examined; synonymised by Townes et al. (1961: 273).

Enicospilus nigrimarginalis Cushman, 1937: 311; HT ♂ from Taiwan, DEI, not examined; synonymised by Townes et al. (1961: 274).

Specimens examined.

Total of 49 specimens (44♀♀5♂♂): Japan (8♀♀3♂♂), Sri Lanka (2♀♀), Taiwan (34♀♀2♂♂).

Type series: HT ♀ of Eniscospilus (sic) dasychirae Cameron, 1905, Pundaluoya, SRI LANKA, I.1899, P. Cameron leg. (NHMUK, Type 3b.1267); HT ♀ of Eniscospilus (sic) horsfieldi Cameron, 1905, Peradeniya, SRI LANKA, IX.1902, P. Cameron leg. (NHMUK, Type 3b.1265).

Distribution.

Australasian, Eastern Palaearctic, and Oriental regions ( Yu et al. 2016); this is a predominantly Oriental species.

JAPAN: [ Ryûkyûs] Okinawa ( Chiu 1954; Gauld and Mitchell 1981; present study). Though this species is widely distributed in Southeast Asia, it is restricted to Okinawa in Japan.

Bionomics.

Recorded as a parasitoid of several species of Erebidae (subfamily Lymantriinae ) ( Gauld and Mitchell 1981; Chiu et al. 1984; Chen et al. 2009) and Noctuidae ( Tang 1990), although there are no host records from Japan.

Differential diagnosis.

This species is readily distinguishable from all other Enicospilus species by the unique small drop-shaped and isolated proximal sclerite of fore wing fenestra, as in Fig. 15F .
