Current projects: Revision of the genus Hemistephanus Enderlein, 1906 (Hymenoptera: Stephanidae).

Request for help and cooperation: I have been looking for the types of Hemistephanus peruanus and H. pehlkei (Enderlein, 1906) [Stephanidae], but after writing to several museums in Europe, USA and Canada, I am still unable to locate them. The species were described from just one specimen each, and now I have evidence that they could be synonymous with previous described species of Cameron and Westwood. Any information regarding the location of these types will be highly appreciated.

Museum notes: The entomological collection at Purdue University has nearly 1,500,000 mounted insects, most from USA, but also from countries in South America and Africa. There is no estimate of the number of Ichneumonoidea, but most of the Hymenoptera are non-identified ichneumonids. This collection may not be known by many professionals since Purdue's major emphasis is not on systematic research.
