Lampronycteris brachyotis (Dobson, 1879)

Fig. 4

Taxonomy. Lampronycteris Sanborn is a monotypic genus represented by L. brachyotis Dobson, 1879 . It is morphologically similar to Glyphonycteris O. Thomas, 1896 , Micronycteris Gray, 1866 , Neonycteris Sanborn, 1949 , and Trinycteris Sanborn, 1949 , which also occur in Brazil ( Williams and Genoways 2008, Nogueira et al. 2014). Lampronycteris can be distinguished from Micronycteris by the lack of an interauricular band of skin connecting the ears (present in Micronycteris ); from Neonycteris by the larger size (forearm> 35mm in Lampronycteris ); from Trinycteris by the calcar equal or larger than foot, and for the ear larger than 16 mm; and from Glyphonycteris also by the calcar equal or larger than foot, and for shorter and narrower upper incisors (which are similar to canines in Glyphonycteris – Williams and Genoways 2008, Díaz et al. 2016, López-Baucells et al. 2016). The PECB specimen (ZSP 040; see Table 3 for measurements) has the diagnostic characters previously described for L. brachyotis (see Sanborn 1949, Medellín et al. 1985, Nogueira et al. 2007b, Williams and Genoways 2008), including: pointed ears lacking an interauricular band of skin; calcar slightly longer than foot; upper incisors shorter and in line with canines; dorsal fur bicolored, with pale-orange basis and orange-brown tips; head, throat and chest bright orange; the ventral fur pale orange with white regions caused by the absence of melanocytes (piebaldism); ears, wings and membranes dark brown (wings and membranes also presented some white spots).

Distribution. In Brazil the species occurs in the Amazon, Cerrado and Atlantic Forest biomes, in the states of Acre, Amazonas, Goiás, Rondônia, Pará, Tocantins, Piauí, Bahia, Espírito Santo, São Paulo, Mato Grosso, and Paraná ( Tavares et al. 2008, Brandão et al. 2016, Reis et al. 2017). In São Paulo the species is known for two southern localities ( Garbino 2016). This is the third record for the species in the state.

Field observations. The only specimen was captured in May. It is an adult non-reproductive female captured in a mist-net suspended 8 m over a small stream in sampling site M5 (Appendix 1).
