Vampyressa pusilla (Wagner, 1843)

Fig. 27

Taxonomy.In Brazil, Vampyressa Thomas, 1900 is currently represented by V. pusilla (Wagner, 1843) and V. thyone Thomas, 1909 ( Nogueira et al. 2014). In Brazil, V. thyone was recorded only in Amazon, in the states of Acre, Amapá, Amazônia and Rondônia. Vampyressa pusilla is slightly larger (forearm 32.3 to 36.0 mm) than V. thyone (forearm 29.3 to 34.0 mm). Additional external characters that distinguish these species are hairier legs and forearm in V. pusilla and legs and forearm relatively less furred in V. thyone ; dorsal fur longer and clearly extending beyond the uropatagium edge, forming a fringe in V.pusilla , while in V. thyone the fur is shorter not extending beyond the uropatagium edge; noseleaf uniformly brown in V. pusilla and with a yellowish outer edge in V. thyone ; and margin of ears faintly paler in V. pusilla and yellow in V. thyone ( Lim et al. 2003, Arroyo-Cabrales 2008, Tavares et al. 2014, Reis et al. 2017). The specimens from PECB (ZSP 058; see Table 7 for measurements) have the set of characters listed above to V. pusilla , and presented a tetracolored dorsal fur, with narrow whitish basis, followed by a mid brownmid-brown band, a paler light brown band and mid brown tips; and venter weakly bicolored, with mid brown basis and grayish brown tips.

Distribution. In Brazil, the species is recorded in the Atlantic Forest, Cerrado and Pantanal biomes, in the states of Goiás, Mato Grosso do Sul, Bahia, Alagoas, Minas Gerais, Espírito Santo, Rio de Janeiro, São Paulo, Paraná, Santa Catarina and Rio Grande do Sul ( Tavares et al. 2008, Reis et al. 2013). In São Paulo the species is represented by few records from sparse localities, but all the vegetational formations ( Garbino 2016).

Field observations. In September we captured an adult male in a mist-net set at ground-level on a wide trail in sampling site M21 (Appendix 1).
