Cotesia Cameron, 1891
See diagnosis in Fagan-Jeffries & Austin (2020). Cotesia can be recognised amongst the other genera of Microgastrinae found in Australia by “the absence of a fore wing areolet; possessing a short inflexible hypopygium and a short ovipositor; T1 generally parallel-sided or broadening posteriorly (occasionally T1 narrowing posteriorly but never to the extent as in Glyptapanteles) and T2 normally broad and rectangular. Often species have the propodeum with a medial carina, and the propodeum, T1 and T2 coarsely sculptured.”
