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.
