Aleochara peeziana LOHSE collected in cow dung near Dorohusk (Lublin Up-land, SE Poland) is new to the Polish fauna. Records of 28 species of Aleocharinae new to the Lublin Upland (19 species), Roztocze (8 species) and Podlasie (2 species) are also given. Five of the recorded species are rare in Poland: Schistoglossa aubei (BRIS.), Pycnota paradoxa (MULS. et REY), Atheta arctica (THOMS.), Oxypoda procerula MANNH and O. funebris KR.
The paper presents localities of 46 species of rove beetles of Aleocharinae (Coleoptera: Staphylinidae) in Beskid Zachodni Mts. (Southern Poland). Two species are new to the Polish fauna: Amischa filum (MULSANT et REY, 1870) and Atheta strupiiana (SCHEERPELTZ, 1960). 22 species were recorded for the first time in Beskid Zachodni Mts.
This paper describes the morphological ultrastructure of the previously unknown final larval instars of the obligate myrmecophilous rove-beetle species Lomeckusa pubicollis. Diagnostic larval characters for the genus Lomechusa are proposed for the first time. At present, this paper is the only up-to-date, detailed and richly illustrated description of the external structures of larvae representing the Lomechusina subtribe. The features of L. pubicollis larvae described here correspond with the abiotic (e.g. absence of ocelh, white body) or biotic conditions (e.g. stumpy body, short legs, absence of urogomphi, dense and asymmetrical chaetotaxy, membranous cuticle) of the anthill, including the passive lifestyle resembling that of the host larvae Formica truncorum, in conjunction with a unique behaviour pattern in the myrmecophileant relationship. Morphological similarities between mature larvae of L. pubicollis and workers of Formica truncorum, the host of this myrmecophile, are also listed. The morphological structure of L. pubicollis larva with the so far best-known larvae of another myrmecophile from the Lomechusini tribe Fella laticollis living in the peripheral zones around the nest, was compared. The different lifestyles of the two species is reflected in the morphological structure of their larvae, particularly: chaetotaxy, structure of setae, ocelli, structure of mouthparts, legs and urogomphi. The characteristics of the morphological structure peculiar to L. pubicollis larva in conjunction with well-developed chemical mimicry, they enable complete adoption and integration in the ant nest, which at such an advanced level appears to be unique compared to other staphylinid myrmecophiles.
Atheta obtusangula Joy is a new to the Polish fauna species of rove beetle. One specimen was collected in leaf litter in an alder forest. Locality: the Brda River valley near Stara Brda Pilska (UTM - XV47).
Leptusa laevicauda Scheerpeltz is a species of rove beetle new to the Polish fauna. It was collected in the soil sample from under the ferns on the slope of Kińczyk Bukowski Mt. (1200-1205 m. a. s. l.).
The first Polish record of an aleocharine rove beetle, Cypha suecica (PALM), is given, on the basis of a male specimen collected near Wrocław, Lower Silesia (WS Poland).
Family Staphylinidae (Coleoptera) in KŁAPACZ 'S collection contains 479 species collected in the years 1909-1956 mainly from Western Ukraine and Lower Silesia. The second part of this paper comprises 5 staphylinid subfamilies: Staphylininae, Habrocerinae, Tachyporinae, Aleocharinae, Micropeplinae.
Atheta nidicola (Johansen, 1914), a new species to the fauna of Poland, was collected in the nesting box of Parus sp. in Stara Brda Pilska (Pomeranian Lake District).
