Thyroptera discifera

(Lichtenstein and Peters, 1854)

VOUCHER MATERIAL (TOTAL = 1): Jenaro Herrera (MUSM 5546); see table 55 for measurements.

UNVOUCHERED OBSERVATIONS: None.

IDENTIFICATION: Thyroptera discifera is distinguished from other congeners by the following combination of characteristics: unicolored yellowish-brown ventral pelage; proximal portion of the forearm well furred; adhesive disk at base of thumb circular; calcar with just one posterolaterally projecting lappet; foramen ovale small; outer upper incisor with mesial cusp larger than distal cusp; both cusps on the outer upper incisor obliquely arranged relative to the long axis of the toothrow; first upper premolar elongated in occlusal view; and outer lower incisor with two small accessory cusps (mesostyle and distostyle) (Velazco et al., 2014; López-Baucells et al., 2018). Descriptions and measurements of T. discifera were provided by Wilson (1978), Pine (1993), Solari et al. (2004), Bezerra et al. (2005), Gregorin et al. (2006), and Velazco et al. (2014). Two subspecies are currently recognized, of which only the nominotypical form occurs in South America (Wilson, 2008a).
