Distribution. This species is recorded from the following countries: Brunei ( Gauld & Mitchell, 1981; Gauld, 1985a), China ( Tang, 1990), India ( Nikam, 1980; Gauld & Mitchell, 1981), Indonesia ( Enderlein, 1921; Gauld & Mitchell, 1981), Malaysia ( Gauld & Mitchell, 1981), Philippines ( Gauld & Mitchell, 1981), Taiwan ( Chiu, 1954; present study) and Vietnam ( Gauld & Mitchell, 1981).

Biology. Unknown.

Remarks. This species is a readily distinguishable species from other Enicospilus based on the characteristic morphology of the fore wing veins and alar sclerites, but it has a wide range of variation on fore wing morphology, such as the shape of Rs+2 r and form of alar sclerites, as mentioned above. This suggests that this species may be a species complex and, if the species is split, E. henrytownesi could end up being a synonym of E. zeugos .

The author examined the holotype of E. henrytownesi and it has the typical morphology of Taiwanese E. grammospilus . Hence, E. henrytownesi is synonymized with this species herein.
