Sarcophagides (Diptera) parasites de Porthetria dispar (L.) en Sardaigne et leur cartographie dans le réseau U. T. M.

Eight species of Sarcophagan dipterans we obtained from laboratory cultures ofPorthetria dispar(L.), a defoliator of cork oak forests in Sardinia. Of these species: -Parasarcophaga exuberansPand. andParasarcophaga portschinskyiRohd. are new to the italian fauna; -Parasarcophaga tibialisMacq.,Parasarcophaga tuberosaPand.,Parasarcophaga uliginosaKram. andPseudosarcophaga affinisFall. are new to the sardinian fauna; -Parasarcophaga exuberansPand.,Parasarcophaga miseraWalk.,Parasarcophaga tuberosaPand. andThyrsocnema corsicanaVill. are described as being entomophagous for the first time.P. disparis previously unrecorded as a host ofParasarcophaga tibialisMacq., while forParasarcophaga uliginosaKram. 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 theEuropean Invertebrate Survey, (chairman: Prof. Dr. JEAN LECLERCQ, Gemblaux-Belgium), U. T. M. code Jists of aIl Sardinian towns were compiled.
