Micronycteris schmidtorum Sanborn, 1935

Fig. 6

Taxonomy. Micronycteris schmidtorum belong to the “pale venter” group, and can be distinguished from other pale venter species based on several morphological features. Micronycteris schmidtorum and M. brosseti are morphologically closer. Both present intermediate interauricular band with moderate notch, have the calcar longer than the hindfoot, and the dorsal fur larger than 7 mm, while in M. minuta , M. homezorum and M. sanborni the band is high and deep-notched, the calcar is equal or smaller than the hindfoot, and the dorsal fur is smaller than 7 mm ( Simmons and Voss 1998, Williams and Genoways 2008). M. schmidtorum and M. brosseti can be distinguished based on tibia length (> 14.5 mm in M. schmidtorum , and <14.0 mm in M. brosseti ) and fur length on outside of medial third of pinna (> 5 mm in M.schmidtorum , and <4 mm in M. brosseti – Simmons and Voss 1998, Williams and Genoways 2008). The specimen from PECB (ZSP 013; see Table 3 for measurements) presented all the characters described for M. schmidtorum . The dorsal fur (ca 7.5 mm) is bicolored with light brown basis and nut-brown tips, the venter is tricolored with whitish basis and tips, and a brown mid band. The posterior surface of the forearm and the proximal third of the uropatagium are sparsely furred. Intermediate interauricular band with moderate notch. The calcar is larger than the foot, and fur length outside of medial third of pinna reaches 5.5 mm.

Distribution. The species was previously recorded in the Amazon, Caatinga, Cerrado and Atlantic Forest, in the states of Amapá, Amazonas, Pará, Tocantins, Mato Grosso, Maranhão, Paraíba, Pernambuco, Alagoas, Sergipe, Bahia, and Minas Gerais ( Rocha et al. 2017a). Our specimen represents the first record of M. schmidtorum for São Paulo, extending the species distribution in more than 700 km southward from the southernmost locality, in the Parque Estadual do Rio Doce, Minas Gerais ( Tavares and Taddei 2003) ( Fig. 16).

Field observations. We captured one adult male in October, which was taken in a mist-net elevated 8 m over a wide trail in sampling site M4 (Appendix 1).
