Lophostoma carrikeri (Allen, 1910)

VOUCHER MATERIAL (TOTAL = 2): Isla Muyuy (MUSM 21175), Jenaro Herrera (MUSM 6977); see table 32 for measurements.

UNVOUCHERED OBSERVATIONS: One individual of Lophostoma carrikeri was captured at the Quebrada Buenavista locality during the Yavarí Rapid Biological Inventory (Escobedo, 2003).

IDENTIFICATION: Until quite recently, three species of white-bellied Lophostoma were recognized as valid: L. carrikeri , L. kalkoae , and L. yasuni (see Velazco and Gardner, 2012). However, Camacho et al. (2016) examined the holotype and only specimen known of L. yasuni using morphological and molecular approaches and concluded that it was conspecific with L. carrikeri , and that yasuni should thus be regarded as a junior synonym. This species can be distinguished from other members of the genus by the following combination of features: pale to whitish fur on the throat; lack of postauricular patches; proximal one-third of the dorsal surface of forearm sparsely covered by short hairs; deeper basisphenoid pits with septum conspicuously narrower; and presence of a weak indentation on the lingual cingulum of each upper canine (Velazco and Gardner, 2012). Descriptions and measurements of L. carrikeri were provided by Allen (1910), Goodwin (1942), Swanepoel and Genoways (1979), Genoways and Williams (1980), Williams and Genoways (1980a), McCarthy et al. (1983), Gribel and Taddei (1989), McCarthy et al. (1992), Simmons and Voss (1998), Lim et al. (1999), Lim et al. (2005), Zortea et al. (2009), Velazco and Cadenillas (2011), Velazco and Gardner (2012), Camacho et al. (2014, 2016), and Brandão et al. (2020). No subspecies are currently recognized (Camacho et al., 2016).

Ascorra et al. (1993) and Velazco and Gardner (2012) correctly identified specimens from the Yavarí-Ucayali interfluve as Lophostoma carrikeri . Our voucher material conforms to previous descriptions of the species, with measurements that fall within the range of size variation previously documented for L. carrikeri .

REMARKS: No definite ecological information accompanies recorded captures of Lophostoma carrikeri from our region.
