Cotesia geometricae Austin, 2000 in Schumacher et al. 2000: 11 (holotype, ♀, ANIC).

Diagnosis

Cotesia geometricae can be separated from all other species of Cotesia currently described from Australia and Papua New Guinea by the following combination of characters: anteromesoscutum punctulate, much smoother than most other species; T3 only sparsley setose, mostly in posterior third; T1 parallel sided; fore wing vein 2RS not extending past junction with r, not creating a ‘stub’, hypopygium not emarginate.

Material examined

Paratypes

AUSTRALIA • 2 ♀♀; Victoria, Alona, Dow Chemical Plant; 8 Jul. 1994; ex. Mnesampela privata (Guenée, 1857) larvae (Lept: Geometridae ); WINC.

Distribution

Currently known from Victoria and the Australian Capital Territory (from examined material and original description).

Host

Mnesampela privata (Geometridae) , gregarious (from original description).

Remarks

As this species is only recently described and we feel that the description is relatively complete, we provide only new characters or measurements relevant to its diagnosis, and refer otherwise to the description in Schumacher et al. (2000).
