Enicospilus erythrocerus (Cameron, 1905) Figure 16

Pleuroneurophion erythrocerus Cameron, 1905a: 121; HT ♀ from Sri Lanka, NHMUK, examined.

Allocamptus orientalis Uchida, 1928: 230; LCT ♀ from Okinawa, designated by Gauld and Mitchell (1981: 175), SEHU, examined; synonymised by Townes et al. (1961: 275); junior secondary homonym of Enicospilus orientalis (Morley, 1913).

Enicospilus hirayamai Uchida, 1955: 120; replacement name for Enicospilus orientalis (Uchida, 1928).

Specimens examined.

Total of 14 specimens (12♀♀2♂♂): Japan (2♀♀1♂), Malaysia (6♀♀), Philippines (1♀), Sri Lanka (3♀♀), Taiwan (1♂).

Type series: HT ♀ of Pleuroneurophion erythrocerus Cameron, 1905, Peradeniya, SRI LANKA (NHMUK, Type 3b.1214); LCT ♀ of Allocamptus orientalis Uchida, 1928, Okinawa Pref., Ryûkyûs, JAPAN, VII.1926, Hirayama leg. (SEHU).

Distribution.

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

JAPAN: [ Ryûkyûs] Okinawa ( Uchida 1928; present study).

Bionomics.

Recorded from Erebidae by Sharma (1985).

Differential diagnosis.

This species especially resembles E. grandis (Cameron, 1905) and E. plicatus ( Brullé, 1846), but is distinguishable by the smaller size, shorter antennae, and more matt and uniformly punctate meso- and metapleuron (Fig. 16A, E ). Other than this species, all Japanese Enicospilus species have at least one fore wing sclerite; hence, it is fortunately very easily identifiable.

Remarks.

Allocamptus orientalis was described based on two females and one male from Okinawa and Taiwan ( Uchida 1928). Although the Taiwanese specimen was designated as the lectotype by Gauld and Mitchell (1981), the lectotype label was attached to a Japanese specimen.
