Family Thyropteridae Miller, 1907

The Neotropical family Thyropteridae includes a single genus with five species characterized by small size; the presence of a fleshy circular disk on the sole of each foot; a fleshy oval or circular disk attached by a short pedicle to the base of each thumb; and fusion of the soft tissues of digits III and IV of each foot to form a single conjoined structure (Simmons and Voss, 1998; Velazco et al., 2014). Velazco et al. (2014) provided a key to the species, of which four are represented in the voucher material we examined from the Yavarí-Ucayali interfluve.
