Descriptive notes.
Head—body 64-73 mm, tail 59-70 mm, ear 34-38 mm, hindfoot 17-19 mm, forearm 59-63 mm. Marinkelle’s Sword-nosed Bat is one of the largest species of
Lonchorhina
. Dorsal fur is reddish brown, with dark-based hairs for almost onethird of their lengths and palertips, giving fur a frosted look. Dorsal fur is long (c.
12 mm
); ventral fur is much shorter (6-7 mm) and paler, close to brownish gray, with pale tips. Marinkelle’s Sword-nosed Bat has an unusually long noseleaf and proportionally long ears, almost as long as noseleaf. Alae sellae are ornamented with tiny warts, and laminae infranarialis is distinctive. Wing membranes are blackish and sparsely haired with very short white hairs. Forearms are furred for only one-third of their lengths. Third metacarpal is largest in series, and fourth is shortest. Short hairs, notvisible to the naked eye, cover dorsal surfaces of uropatagium and legs. Long tail extends to posterior margin of long uropatagium, giving it a pointy look. Skull has short wide rostrum, and frontals are flat between orbits. Nasals end well behind premaxillae. Length of C'-M?is slightly shorter than breadth at M®. Postorbital is very constricted. Braincase is elevated, showing no depression on its posterior portion. Temporal and lambdoid crests are inconspicuous. Hypocones of upper molars are little developed, and lower incisors are somewhat trilobed. Vertebrae formula is seven cervical, twelve thoracic, six lumbar, six sacra, and nine caudal.

Isolated rock hills known as inselbergs, usually surrounded by tropical savanna grasslands and gallery forests in the oriental Llanos, at elevations of 180-240 m.

), Orange-throated Bats (
Lampronycteris brachyotis
), and Lesser Dog-like Bats (
