FOSSIL BATS OF THE AMERICAS

Mormoopidae:
Mormoops magna
Type specimen: Instituto de Zoología, Academia de Ciencias de Cuba 344.1, left humerus.

Type Locality and Horizon: Cueva de los Masones, Trinidad, Las Villas Province, Cuba; Quaternary; cave deposits (wall patches of bone-bearing guano = layer M12).

Diagnosis (from Silva Taboada 1974): Humerus like in Mormoops megalophylla, but larger and stouter.


Pteronotus pristinus
Type specimen: Instituto de Zoología, Academia de Ciencias de Cuba 324.1, cranium with all molars, second premolars, and left periotic.

Type Locality and Horizon: Cueva de los Masones, Trinidad, Las Villas Province, Cuba; Quaternary; cave deposits (layer M2).

Diagnosis (from Silva Taboada 1974): Largest known member of the subgenus Chilonycteris. From Pteronotus personatus, P. pristinus may be distinguished primarily by the condition of the infraorbital canal (infraorbital foramen opening at the end of a short tubular canal in the latter), thus approaching the Antillean species P. macleayi and P. fuliginosus. Pteronotus pristinus more closely resembles P. fuliginosus than P. macleayi in relatively shorter rostrum. This makes zygomatic breadth greater than half the length of the skull (incisors excluded) in P. fuliginosus and P. pristinus, whereas in P. macleayi it is equal to or less than half the length of the skull. The new species differs from P. fuliginosus in the shape of the braincase, which in P. pristinus is more rounded when viewed from above, and flatter in dorsal profile. From all three previously known members of the subgenus, P. pristinus may be readily distinguished by the noticeable difference in size.
