UNVOUCHERED OBSERVATIONS: None. IDENTIFICATION: Thyroptera lavali is distinguished from other members of the genus by the following combination of characteristics: bicolored brownish ventral pelage; proximal portion of the forearm sparsely haired; adhesive disk at base of thumb oblong; calcar with just one posterolaterally projecting lappet; foramen ovale large; outer upper incisor mesial and distal cusps subequal in size; both cusps on the outer upper incisor perpendicularly arranged relative to the long axis of the toothrow; first upper premolar circular in occlusal view; and outer lower incisor lacking accessory cusps (Velazco et al., 2014; López-Baucells et al., 2018). Descriptions and measurements of T. lavali have been provided by Pine (1993), Solari et al. (2004), Gregorin et al. (2006), and Velazco et al. (2014). No subspecies are currently recognized (Wilson, 2008a). The type series of Thyroptera lavali was comprised of four specimens from Quebrada Esperanza (Pine, 1993). Ascorra et al. (1993) identified the specimen from Jenaro Herrera as T. discifera , but Solari et al. (2004) correctly reidentified it as Thyroptera lavali . REMARKS: No ecological information is available about Thyroptera lavali in our region.
