Forró, L.; Farkas, S.: Checklist, preliminary distribution maps, and bibliography of woodlice in Hungary (Isopoda: Oniscidea)

terrestrial and aquatic detritus were the subjects of several papers (Hornung 1981, Pobozsny 1978, Szlávecz 1985, 1991, 1992, 1993, Szlávecz & Maiorana 1990, 1998, Szlávecz & Pobozsny 1995). Recently, the u biquitous Porcellio scaber Latr., has become a test species for exotoxicological essays (Fischer et al. 1997, Hornung et al. 1998). Taxonomy The nomenclature and taxonomy used in the present paper is based on Gruner (1966). 1. Pongrácz (1936) mentioned Tithanetes albus Schiödte, 1849 from Hungary in the cave of Aggtelek. Dudich (1942) considered it erroneous, therefore this data was not included in the present checklist. 2. Csiki (1926) and Dudich (1942) also listed Tracheoniscus magyaricus (Verhoeff, 1907) from Budapest. In the most recent revision of the genus Trachelipus Schmidt (1997) considered it (Porcellio magyaricus) as a nomen nudum, therefore the species was omitted from the checklist. 3. Dollfus (1901) reported Armadillidium pallasi and, based on this record the species was also listed by Csiki (1926) and Dudich (1942). However, because only the vague locality "Hungary" was given we omitted it from the present checklist. 4. The data of Tracheonicus affinis C. L. Koch (Csiki 1926, Dudich 1942) from Budapest is problematic, too. Schmidt (1997) reported that Verhoeff misidentified and named a specimen of Trachelipus difficilis as Tracheoniscus affinis. After this, many author used incorrectly the name Tracheoniscus affinis C. L. Koch, 1841 because this is not identical with Porcellio affinis C. L. Koch which is the synonym of Trachelipus rathkii Brandt, 1833. It is possible that the pending specimen belongs rather to T. rathkii Brandt, 1833. 5. It cannot be decided which species could be the following ones: Trichoniscus germanicus Verhoeff (Csiki 1926), Hyloniscus vividus C. L. Koch, Trichoniscus germanicus Verhoeff, Hyloniscus narentanus Verhoeff (Dudich 1942). Csiki (1926) mentioned Trichoniscus germanicus Verhoeff from the Mecsek Mts. Dudich (1942) cited it as a synonym of Hyloniscus vividus C. L. Koch. Simultaneously, four rows below Hyloniscus narentanus Verhoeff appears as the synonym of H. vividus C. L. Koch, too. Wächtler (1937) has the opinion that H. riparius C. L. Koch, 1838, H. vividus Koch, 1841 and Itea riparia C. L. Koch are the same species. Moreover, Wächtler (1937) recommends that it would be better the species which was described by Koch (1841) as Itea vivida (= H. vividus Verhoeff) to name as H. narentanus Verhoeff, 1908. Gruner (1966) reports that all the Itea riparia C. L. Koch, 1838, Trichoniscus germanicus Verhoeff, 1908 and Hyloniscus vividus Verhoeff, 1908 are synonyms of H. riparius C. L. Koch, 1838, but Itea vivida C. L. Koch, 1841 is another species. The problem cannot be resolved without the re-examination of the original specimens. 6. Lantos (1985) reported Hyloniscus dalmaticus Verh. (sic) from a mixed oak-pine forest in the Bares Juniper Woodland preservation area. No descriptive details were given by the author, therefore this species was not included in the present checklist.
