Second record of Cercion lindenii (Sel.) in Austria (Zygoptera: Coenagrionidae)
Notulae odonatologicae , Volume 1 - Issue 9 p. 153- 154
C. lindenii is considered a west Mediterranean faunal element (cf. D. ST. QUENTIN, 1960, Zoo!. Jh. Syst. 87: 301-316). The species inhabits only very few regions of Central Europe north of the Alps and is generally regarded as rare. It has been known to occur as far north as Holland and Nordrhein-Westfalen (new records in Munsterland, viz. M. STE1NWEGER, 1971, Nalur& Heimal. Munster 31 ; 22-25; R. RUDOLPH, 1976, loc. cil. 36; 86- 87), or in the NE, where isolated populations were reported from the Brandenburger area (U. JAKOB, 1969, Faun. Abh. Mus. Tierkde Dresden 2: 197-239). According to H. LOHMANN (1980, Soc. ini. odonalol. rapid Comm. I: 1-34) the Cercion lindenii population of West Germany in the Rhine area in the last couple of years has definitely increased. However, the species is not indigenous in any other state of Germany and, remarkably enough, it has been reported from Bavaria only once (L. DIRNFELDER, 1982, Libellula 1 (2): 52-55). According to H R. WILDERMUTH (1981, Schweiz. Nalurschutz Sonder- Nr. I, pp. 20-21) C. lindenii occurs in a single area of northern Switzerland, while it is very local in western Switzerland (cf. C. DU FOUR. 1978, Elude faunislique des odonales de Suisse romande. Conserv. Faune Vaud, Lausanne) and in Tessin (J. DE MARMELS & H. SCHIESS, 1978. Boll. Soc. lie. Sci. nal. 1977/ 78; 29-83). It has not been reported recently from central and eastern Switzerland (J. DE MARMELS, 1979, Notul. odonatol. I; 37- -40). In view of this situation, records from the SE area of Central Europe, north of the Alps, merit special attention. The only Austrian record, a teneral 3 from the surroundings of Linz. Upper Austria, was made by G. THEISCHINGER (1966, Nalurk. Jb. Linz 12: 175-178).
