Material examined. One female collected in a yellow pan trap at Venissieux , Rhone , France , on 6 August 1991 .
The species has been recorded from several European countries: Austria, Croatia, former Czechoslovakia, Finland, Germany, Greece, Hungary, Italy, Moldavia, Sweden, Switzerland and Ukraine (Kozlov 1971, 1988; Huggert 1979). Therefore, it is new for France.
Hosts are spider eggs, probably such as Meta segmentata (Clerck) (Huggert 1979).
Morphology. Kozlov (1971) illustrated I. aureopetiolatus , and Huggert (1979) more accurately redescribed and illustrated the species.
