Abstract

Eight species of Sarcophagan dipterans we obtained from laboratory cultures of Porthetria dispar (L.), a defoliator of cork oak forests in Sardinia. Of these species: - Parasarcophaga exuberans Pand. and Parasarcophaga portschinskyi Rohd. are new to the italian fauna; - Parasarcophaga tibialis Macq., Parasarcophaga tuberosa Pand., Parasarcophaga uliginosa Kram. and Pseudosarcophaga affinis Fall. are new to the sardinian fauna; - Parasarcophaga exuberans Pand., Parasarcophaga misera Walk., Parasarcophaga tuberosa Pand. and Thyrsocnema corsicana Vill. are described as being entomophagous for the first time. P. dispar is previously unrecorded as a host of Parasarcophaga tibialis Macq., while for Parasarcophaga uliginosa Kram. this host has been hitherto unrecorded in Europe. Biogeographical data for these species were analysed in terms of their spatio-temporal dinamics, using a 10 km x 10 km grid U. T. M. map of Sardinia for reference. Using the metodology of the international project of the European Invertebrate Survey, (chairman: Prof. Dr. JEAN LECLERCQ, Gemblaux-Belgium), U. T. M. code Jists of aIl Sardinian towns were compiled.
