Note 1: After comparison between individuals from french continent [Le Grau-du-Roi, department of Gard, on the beach, 22.06.1997 and published by G. Tomasovic, 1998, Notes sur les Asilidae Paléarctiques (Diptera, Brachycera) 4-8, Bull. Annls Soc. r. belge Ent. 134 : 133-138. As Andrenosoma leucogenys Séguy, 1952] and individuals from Corsica, personnal catches (Oriental beach, Ghisonaccia, 23.07.1997 and Aleria, 12.07.2000) and one male specimen from the British Museum, sended by Dr.J.Chainey, from also Corsica(Occidental beach, F. Guglielmi, Ajaccio, 20.08.1906) and identified by H. Oldroyd as Andrenosoma albopilosum Villeneuve, 1911. All this specimen belong to Andrenosoma albopilosum Vill., their dististylus are identicals and the Seguy's drawing Nº2(p. 195) in his paper [1952, Andrenosoma nouveaux de France, Rev. Fr. d'Ent., 19 : 192-196] isn't the dististylus of A. leucogenys but that's of albopilosum; it's certainly a mistake. Unfortunately the "type", one unique specimen of A. leucogenys, I can't find it in the entomologicals collections in Paris! Very disturbing!!

Note 2: Mike Taylor is working on Andrenosoma cornuta Oldroyd, 1972. If you have material from Greece and Turkey, please get in touch with him. It seems to be that a new desription of this species is necessary. His address is:
