Notes on Asilopsis fusculus Cockerell, 1921

While preparing the description of Kishenehnoasilus bhl sp. nov., it seemed important to reexamine the holotype of Asilopsis fusculus , which is deposited in the NMNH. This fossil (Figure 7.1-2) is based on a single, partially broken wing, which might make a placement difficult. It was immediately obvious that the wing does not have any features of an Asilidae , but that it clearly belongs to another family. Through the help of Jon Gelhaus and Herman de Jong, we established that the wing venation is similar to that of Cylindrotomidae (Tipuloidea) and Asilopsis fusculus is here transferred to that family (see under Cylindrotomidae for a redescription and further comments).
