Enicospilus henrytownesi Chao and Tang, 1991: 51; HT ♀ from Taiwan, EMUS, examined; syn. nov.

Specimens examined.

Total of 5 specimens (3♀♀2♂♂): Japan (1♂), Taiwan (3♀♀1♂).

Type series: HT ♀ of Enicospilus zeugos Chiu, 1954, Urai, TAIWAN, VI.1931, J. Sonan leg. (TARI); HT ♀ of Enicospilus henrytownesi Chao & Tang, 1991, Wushe (1,150 m), TAIWAN, 26.IV.1983, H. Townes leg. (EMUS).

Distribution.

Oriental region ( Yu et al. 2016).

Newly recorded from Japan.

JAPAN: [ Ryûkyûs] Okinawa.

Bionomics.

Unknown.

Differential diagnosis.

This species can very easily be distinguished from all other Enicospilus by the unique shape of the fore wing sclerites (Fig. 55F ).

Remarks.

Both E. zeugos stat. rev. and E. henrytownesi syn. nov. had been synonymised under E. grammospilus (Enderlein, 1921) by Gauld and Mitchell (1981: 316) and Shimizu (2018: 93) respectively. However, the shape of fore wing veins and sclerites and the results of DNA barcoding analysis indicate that E. zeugos stat. rev. (with E. henrytownesi syn. nov. as a junior synonym) is easily separated from E. grammospilus , hence we propose a revised status for E. zeugos stat. rev. here.
