Pipistrellus kuhlii (Kuhl, 1817) has a Palearctic and Afrotropic distribution. It ranges from the Canary Islands eastward to 93◦ E in S Asia, most of Africa and throughout S and W Europe – from the Iberian Peninsula and France to S Germany, Switzerland, Austria, Hungary, the Balkan states and SW Russia (VERNIER & BOGDANOWICZ, 1999; HORACEK et al., 2000; SPITZENBERGER & BAUER, 2001; BOGDANOWICZ, 2004). On 31 May 2006 an adult male P. kuhlii was recorded in City Park of Nitra (Nitrianska pahorkatina Highlands, W Slovakia, 48◦18′ N, 18◦04′ E; 140 m a.s.l.). The bat was caught in a 3.5 m high mist net erected on a bank of a small fishpond (ca. 200 × 80 m) surrounded by willows. External measurements of the bat were: body 43 mm, tail 40 mm, forearm 32.8 mm, hind foot 6 mm, ear 11 mm, tragus 5 mm, 3 finger 58.2 mm, 5 finger 41.2 mm and wingspan 235 mm. The weight was 4.9 g. The bat was yellow-brown in color on the dorsal side of its body; the ears and face were brown. The wing was bordered by a 1–1.5 mm contrasting white margin between the 3 finger and the tail (Fig. 1). The first upper incisor had a single cusp and the second incisor was almost impossible to recognise (15× magnifying glass). At the same location, several Pipistrellus nathusii (Keyserling et Blasius, 1839) were caught simultaneously with the P. kuhlii, so it was possible to compare the characteristics of both these quite similar species. The bat was photographically documented, banded (SLOVAKIA A 0597), allowed to drink and released again in the park, at night, on 4 June 2006. The nearest record of this species is from Vienna, Austria, 130 km W (BOGDANOWICZ, 2004). Nitra is now the most northerly location recorded for this species in C Europe and it is consistent with its anticipated spread northwards (FIEDLER et al., 1999; BOGDANOWICZ, 2004). The occurrence of this species in an urban area was also typical for this species, as it exhibits one of the highest degrees of synanthropy among bat species in Europe (BOGDANOWICZ, 2004). It is interesting that four congeneric species were hunting together in the park: Pipistrellus kuhlii, P. pipistrellus (Schreber, 1774), P. pygmaeus (Leach, 1825) and P. nathusii. Although P. kuhlii was already listed as a member of Slovakian mammal fauna (BABOR, 1943) this was challenged by FERIANC (1946) as unsubstantiated. A Pipistrellus sp. with a white margin on the wing membrane was mistnetted in Kirť (Ipeľska kotlina basin, S Slovakia, 48◦06′ N, Fig. 1. Contrasting white margin on the wing (between the 3rd finger and the tail) is typical character for P. kuhlii.
