摘要

Microchiropteran bats species can be discriminated according to morphometrical, behavioural and genetical features (1) (2). In addition, as bat species often emit distinct echolocation calls, the analysis of signal characteristics is a good identification tool and can even lead researchers to the discrimination of sibling species. In 1993, JONES & VAN PARIJS (3) showed a bimodal distribution in the echolocation calls of the common pipistrelle Pipistrellus pipistrellus (Schreber, 1774) with individuals emitting calls with maximum energy peak around 45kHz and others around 55kHz. Subsequent works have shown that the two phonic types also showed differences in diet, habitat use (4) and social calls (5) (6). Genetic analysis finally separated the two phonic types into different cryptic species P. pipistrellus and P. pygmaeus (Leach, 1825), the common name given to the latter species being soprano pipistrelle (7). The distribution of P. pygmaeus is poorly known because of the recent distinction between the two phonic types. To date, it seems that soprano pipis-trelles occur in Portugal, Sweden (8), Norway (9) and Denmark (7) (9) (10), whereas its sibling species, P. pipistrellus, does not. In other countries: Greece (11), Great Britain (3), Switzerland (12) (13), Northern Ireland (14), Germany (15) (16), France (17), Italy (18), and Spain (19) (16), the two species (P. pipistrellus and P. pygmaeus) are sympatric. Despite its presence in bordering countries, P. pygmaeus has never been identified in the Benelux so far. Two species of pipistrelles are known to occur in Belgium (20): P, pipistrellus is widely distributed in Europe whereas P. nathusii (Keyserling & Blasius, 1839) is much less frequent and usually found around forest edges and riparian habitats (21). Here, we present the first acoustic records of the soprano pipistrelle in Belgium.
