Abstract

Abstract: The region of South Transdanubia covers the south-western part of Hungary, a territory bordered by the Danube and Drava Rivers and the Lake Balaton. In the South-Transdanubia region the sub Mediterranean climate is most characteristic in the hilly area (150–682 m). The author revise the Tortricidae material housed in natural history collections in Hungary. Four species were identified as new records for the South Transdanubia: Cochylimorpha woliniana (Schleich, 1868); Cochylidia rupicola (Curtis, 1834); Cochylidia moguntiana (Rössler, 1864); Xerocnephasia rigana (Sodoffsky, 1829). The species are very locally and rare in Hungary. Several habitats have been destroyed or transformed so the species are endangered. Cochylimorpha woliniana flight begins early in May. Cochylidia rupicola only known in 8–10 localities on various habitats. We know little on Cochylidia moguntiana species. It has been collected from the beginning of the 20th century. One of the most interesting species of research is Xerocnephasia rigana. So far, little knowledge of the distribution and bionomy of the species have been reported. Most of the collecting sites are in the hills and mountain ranges but its occurrences are only sporadic in plains. The author has recently collected Xerocnephasia rigana in the southernmost mountainous region of Hungary, the Villány hills. The species mostly prefers the following habitats: rocky slopes, steppes, karst shrubby woodlands, dry shrubs, sandy grasslands and forest edges. The flying period takes from late April to late July, probably in two generations. The study describes in detail the life history of the four species and voucher specimen’s geographical distribution is depicted on maps. With 13 figures.
