Gozmány, L.: New data to the Microlepidoptera fauna of the Retyezát Range

New Data to the Microlepidoptera Fauna of the Retyezát Range By. L. A. G o z m á n y, Budapest During my research work in connection with coenologic problems of Lepidoptera it became necessary to look foroecologic data on certain species of micromoths. Some phases of my investigation touched on high-mountain foriru and as the Collections of the Natural History Museum in Budapest has a rich material originating from the Retyezát Range ï included in my work'the revision of these collectings. The Retyezát Range is one of the last big groups of the Carpathians' arch, in Rumania, its direction being roughly NE-SW. It has peaks higher than 2400 and even 2500 meters, high alpine regions above snow line. The fiziographic and floral characterization from an entomologie point of view may be found in the first of L. D i ó s z e g h y's papers (1), and, as considerations of space warrant it, ï only allude to this paper without going further into the matter. Lancelot D i ó s z e g h y, the most arduous collector of the lepidopterous riches of this Range, brought together a big material in eleven expeditions to it in the years 1914—-1932. His collectings were partly incorporated in his collection (which, to my best knowledge, perished during the war in his house in Ineu, Rumania), and were partly sent to this Museum in exchange and as presents. Dr. A. Schmidt in Budapest and Prof. H. R e b e 1 in Vienna made the necessary determinations, but there remained also a lot of undetermined material. The same applies to the collectings of Újhelyi, a preparator of this Museum, who also collected in the Retyezát in 1914 (July 10—23). • As some of these identifications and therefore some of the published data in D i ó s z e g h y's papers are deficient I had to re-determine the whoíe material in the Collection, reviding also D i ó s z e g h y's various papers to correct eventual errors. This is the more interesting as some fresh data may throw more light in the connexion of the Retyezát Massif's lepidoptera with other isolated lepidoptera faunas of Southern European Mountains and Ranges, such as I believe to exist with the Yugoslavian Alps, the Austrian and Swiss Alps, and even the Pyrenees. I wish only to point out in the hitherto unpublished material (cf. also Bibliography) such species as Epiblema grandaevana Z., Catoptria monstratanà Rbl., Gelechia klosi Rbl., Gelechia pyrenaica Petry, and Zelleria rufella Tgstr. Then there are some species that revelate connections with Eastern Asian mountainous regions, their western most dispersion being the Retyezát Range : Phaneta abacana Ersch., Phiaris cacuminana Kennel, Laspeyresia junctistrigana Wlsghm., and Cerostoma leaconotella Snellen. Diószeghy collected with the net, sugaring and by artificial light. Owing to these methods there are almost no data on the smallest micros, e. g. the miners. No mine is mentioned in his works, and only a few imagines of mining species enumerated. The miner fauna of the Retyezát (which must be exceedingly
