The biology of many Darwin wasp (Hymenoptera: Ichneumonidae) species is poorly known. Existing museum specimens can potentially be used to get information on e.g. how live, what they eat, and their life cycle is. One example this a 1991 study by Eggleton in which he measured some rhyssine (Ichneumonidae: Rhyssinae) species, the results deduce likely mate. We extend work measuring five tropical ...

Three closely related species of the genus Probles Förster, P. fulgida sp. n., P. korusa sp. n. and P. rukora sp. n., belong to the subgenus Euporizon Horstmann and differ from other Palearctic species of the genus by a combination of long and apically weakly sinuate ovipositor and short temple. These three species are assigned to a newly designated fulgida species-group, and a portion of the k...
