Observaciones de Pipistrellus nathusii (Keyserling & Blasius, 1839) (Chiroptera, Vespertilionidae) en la península ibérica

Resum

Records of Pipistrellus nathusii (Keyserling & Blasius, 1839) (Chiroptera, Vespertilionidae) in the Iberian peninsula
Seventy-two years after the last accepted mention of Pipistrellus nathusii in the Ibenan peninsula, the records described in this paper confirm its current presence in the Basque-Cantabric area (north of Spain). One of them was made in summer and suggests the existence of resident populations. A compilation of al1 iberian records is presented. The small number of available references makes it recommendable that Nathusius’ Pipistrelle may be considered as insuficiently known species (K) in Spain.
