Update compilation on the geographic distribution of Lasiurus ega (Gervais, 1856) (Mammalia, Chiroptera, Vespertilionidae), including the first record for the Caatinga in the state of Paraíba, northeastern Brazil

This study provides the first record of Lasiurus ega (Gervais, 1856) from the Caatinga domain of the northeastern Brazilian state of Paraiba. The specimen was captured in mist-nets set in a grove of mango trees (Mangifera indica L.; Anacardiaceae), an exotic fruit species, on the Tamandua Farm, located in the rural municipality of Santa Terezinha (07o01’ S, 37o23’W), in the semi-arid zone of Paraiba. External and dental skull measurements were taken following standard procedures and compared with the data available on L. ega in the literature. An updated map of the distribution of L. ega in northeastern Brazil is provided. The Caatinga occupies 92% of the area of Paraiba, and its chiropteran fauna is still largely unknown. This record increases the number of bat species now known to occur to 44 in the Paraiba Caatinga, of which 19 are restricted to this biome.
