76 NATURA SOMOGYIENSIS The results of the investigation of the spider fauna (Araneae) of the Látrányi Puszta Nature Conservation Area CSABA SZINETÁR AND BALÁZS KERESZTES The examination of the fauna of the Látrányi Puszta Nature Conservation Area, located close to the Southern shore of Lake Balaton, was carried out between 2000 and 2002. Targetting mostly ground-dwelling species, the examination carried out via Barber pitfall-trapping, handpicking and sweep-netting yielded 152 spider species including Pirata insularis, which is new to the Hungarian spider fauna. It is typically indigenous to fen meadows. The hitherto known spider fauna of Somogy county was enlarged by 24 newly detected species including two protected ones: Atypus piceus and Dolomedes fimbriatus . The high number of indigeneous species is probabaly due to the fact that the relatively small area is rather heterogenic in the composition of its fauna. What's partciularly valuable is the simultaneous presence of species typical of both dry sandy grasslands and of fen meadows. Figure 5. illustrates the similarity between the specimens yielded by the four Barber pitfall-trappings. It is clear to see that although the two fen meadows show a striking similarity (see the squares and the triangles), the areas with alder (see the circles) and the dry sandy grasslands (see the stars) are distinctively different. In spite of their marked perturbation, the sandy grasslands have a rather valuable fauna composition in terms of the ground-dwelling fauna which is clearly and closely related to to sandy habitats examined earlier in the area Dráva-mellék (Darány, Tóthújfalú, Bélavár) and in Belső-Somogy (Nagybajom). Characteristic species of the fauna: Uloborus walckenaerius (Latreille, 1806); Pardosa bifasciata (C.L. Koch, 1834); Oxyopes lineatus Latreille, 1806; Berlandina cinerea (Menge, 872); Xysticus ninnii Thorell, 1872; Pellenes nigrociliatus (Simon, 1875); Sitticus distinguendus (Simon, 1868). Fen meadows and areas with high segde are the habitats of the protected area which have invaluable and unique values and which are best preserved in their original conditions. Large populations of hygro- and photophile ground-dwelling spiders live in these grasslands. The micro-climatic conditions of the ground surface in fen meadows are different from what we can find in shore reeds and sedgy areas at Lake Balaton, though they lie surpisingly on one another.
