Antrocephalus maculipennis Cameron, 1905: 95 (lectotype ♀ (BMNH No. Hym. 5, 258 on pin, selected by Narendran, 1989).

Material.

1 ♀ (RMNH), "S. Vietnam: Dak Lak, Chu Yang Sin N. P., Krong K’Mar, 590-840 m, 22-26.x.2005, Mal[aise] traps 13-23, C. v. Achterberg & R. de Vries, RMNH’05”.

Diagnosis.

This species comes near Antrocephalus niger (Masi) in the key to Oriental species of Antrocephalus by Narendran (1989), but differs from that species in having the fore wing with two dark brown or black infuscations whereas in Antrocephalus niger the fore wing has only one dark infuscation. This species also resembles Antrocephalus cariniceps (Cameron) in general appearance, but Antrocephalus cariniceps has a distinct long pair of basal carinae at the base of T1, whereas in Antrocephalus maculipennis such carinae are absent.

Description.

♀, length of body 5.6-6.6 mm. Black; fore wing with two brown patches: one starting from MV extending to middle or beyond posteriorly; second one extending from latter patch to posterior part of the wing. Body with silvery pubescence. Head wider than mesosoma (excluding tegulae); pre-orbital carina distinct, not joining auricular carina; post-orbital carina slightly indicated, malar groove carinate. Scape reaching anterior ocellus, apex of scutellum well emarginated; anterior pronotal carinae and median tubercles distinct; pits on mesosoma close and interstices narrower than half diameter of a pit and micro-sculptured; propodeum with postspiracular teeth present; metasoma acuminate towards apex.

Host.

Opisina arenosella Walker ( Lepidoptera : Oecophoridae ) ( Pillai and Nair 1993).

Distribution.

India, East Malaysia (Sarawak) ( Narendran 1989), Vietnam (new record).
