Peropteryx

Peropteryx and Peronymus have been traditionally recognized as distinct genera (e.g., Miller, 1907; Sanborn, 1937; Husson, 1962, 1978), and many recent authors have continued to treat them as such (e.g., Brosset and Charles­Dominique, 1990). However, Peronymus and Peropteryx share a unique morphology of the antebrachial wing sac (Sanborn, 1937; Jones and Hood, 1993), and phylogenetic studies have shown that these taxa form a monophyletic group (Griffiths and Smith, 1991). Indeed, the principal distinguishing character of Peronymus leucopterus (the only species referred to the genus) is its white wing membranes, which are clearly autapomorphic. Accordingly, we follow Cabrera (1958), Jones and Hood (1993), and Koopman (1993, 1994) in regarding Peronymus as a junior synonym of Peropteryx . A useful key to the species of Peropteryx so defined was provided by Jones and Hood (1993).
