Abstract: The ant communities of 12 habitats in four marshlands were studied in the Eastern Carpathians. Altogether 11 ant species were identified, but none of the species could be considered a specific relic species of marshlands, though characteristic species could be detected, like Myrmica rubra, M. ruginodis and M. scabrinodis. The sampling procedure seems to be fairly complete. The between and within region comparisons revealed that there were no regional differences in the ant communities, but differences could be attributed mostly to differences in habitat attributes like vegetation and related characteristics. The three most abundant Myrmica species all showed clear habitat preferences, which overlapped just to a lesser extent. The diversity analysis suggested a highly mosaic-like distribution pattern of ants in different habitats, which could be attributed to specific constraint factors acting on the ant species inhabiting mountain marshlands. Thus usually one patch is occupied and dominated by a single species. The existence of this mosaic-like pattern is also supported by the possibility of competition between M. rubra and M. ruginodis. The importance of connecting different scales to elucidate mechanisms creating the observed patterns is emphasized.

Title: Two new species of Aporcelaimellus Heyns, 1965 (Nematoda: Dorylaimida) from the tropics

Author's address: Department of Systematic Zoology and Ecology of the Eötvös Loránd University, Zootaxonomy Research Group of the Hungarian Academy of Sciences, H-1117 Budapest, Pázmány Péter sétány 1/C, Hungary; E-mail:

Abstract: This paper provides descriptions of two new Aporcelaimellus species. Aporcelaimellus amazonicus sp. n. from Brazil is characterized by its size ranged between 1.5 and 2 mm, unusually narrow vulval lips, very thick vagina, and tail measuring one to one and a half anal body widths and possessing a sharply pointed projection. Aporcelaimellus insularis sp. n. from the Seychelle Islands is characterized in having very robust body less than 1.5 mm, heart-shaped vulval lips, very short prerectum and half an anal body width long, mammillate tail. The shape of tail is particularly characteristic for both species.

Abstract: Nineteen species of the genera Leptothorax and Temnothorax are distributed from Mongolia to the Pacific Ocean, these are revised and a key to their identification is provided. Four new species, Temnothorax cuneinodis, T. xanthos, T. pisarskii and T. michali are described from North Korea. L. galeatus Wheeler is synonymised with T. nassonovi (Ruzsky) and L. wui Wheeler is raised to species rank (in the genus Temnothorax).
