Peropteryx kappleri Peters, 1867

VOUCHER MATERIAL (TOTAL = 9): Jenaro Herrera (MUSM 6976), Nuevo San Juan (AMNH 272797–272799, 273086, 273174; MUSM 13225, 15244, 15245); see table 3 for measurements.

UNVOUCHERED OBSERVATIONS: None.

IDENTIFICATION: Peropteryx kappleri is easily distinguished from other members of the genus by its large size (forearm>46.5 mm), uniformly brown wings, absence of a transverse band of skin connecting the ears, a skull with a relatively narrow but dorsally inflated rostrum, small and shallow lateral pterygoid pits separated by the basisphenoid pit, and presence of a posterior cusp on the anterior upper premolar (Lim et al., 2010). Descriptions and measurements of P. kappleri were provided by Sanborn (1937), Goodwin and Greenhall (1961), Husson (1962, 1978), Jones and Hood (1993), Simmons and Voss (1998), Lim et al. (2010), McDonough et al. (2010), and Velazco and Patterson (2019). Two subspecies are currently recognized: P. k. kappleri (Central America to Ecuador, Venezuela, the Guianas, and southeastern Brazil) and P. k. intermedius (southern Peru) (Hood and Gardner, 2008).

Fleck et al. (2002) and Lim et al. (2010) correctly identified our material from Nuevo San Juan as Peropteryx kappleri . The specimen from Jenaro Herrera is morphologically indistinguishable from the Nuevo San Juan material, exhibiting all the diagnostic characters for this species as described by Lim et al. (2010) and noted above. All examined specimens from the Yavarí- Ucayali interfluve are morphologically indistinguishable from French Guianan material reported by Simmons and Voss (1998).

REMARKS: The only definite ecological information about Peropteryx kappleri in our region is from Nuevo San Juan, where we found five roosts of this species, all of them inside hollow logs or on the undersides of fallen trees (table 4). Four roosts were in well-drained primary forest on hilltops or hillsides, but one was in secondary growth from an old blowdown. Peropteryx kappleri was not found roosting with any other bat
