Eastern Cordilleran Nectar Bat

Lonchophylla orienticollina

French: Lonchophylle de la Macarena / German: Ostkordilleren-Nektarfledermaus / Spanish: Loncéfilo de la Macarena

Taxonomy. Lonchophylla orienticollina Davalos & Corthals, 2008 ,

“at the intersection of cafo: Guamalito: and cafio 1a Curia, northern part of the Serrania de la Macarena, San Juan de Arama, 500 m elevation, Departamento del Meta, Colombia.” Specimens corresponding to L. orienticollina were previously listed as L. robusta . Monotypic.

Distribution. E slope of Serrania del Perija and SE slope of Cordillera de Mérida in NW Venezuela, E & W slopes of E Andes Range and N part of Serrania de la Macarena in Colombia, and E slope of E Andes Range in Ecuador.

Descriptive notes. Head-body 61-71 mm, tail 6:5-11 mm, ear 11-18 mm, hindfoot 11-17 mm, forearm 40-47 mm; weight 11-16 g. The Eastern Cordilleran Nectar Bat is medium-sized, with dorsal fur ranging from intense ocherous orange to buckthorn brown and snuff brown and ventral fur light tawny olive. Length of dorsal fur along upper back is ¢.4-8 mm. Dorsal pelage has bicolored hairs, with cream-white bases and ocherous orange to brown tips; ventral hairs are sometimes bicolored, banding almost imperceptible and disappearing toward abdomen. Noseleafis triangular,slightly higher than wide. Pinnae are short, with rounded tips; no furry fringe occurs along uropatagium; and calcar is shorter than foot. Feet and thumbs are long relative to bodysize. Skull shape is distinctive: braincase is tall; rostrum is inflated and short, appearing thick in profile; and palate is wide. Braincase height slopes to rostrum at relatively high angle, visible in profile. In dorsal view, skull appears blunter and shorter, with all features shortened compared with the Orange Nectar Bat ( L. robusta ) of similar size; rostrum is clearly inflated above P*. Lingual cusp is well developed in P*, and M' is longer (anteroposterior axis) than M*.

Habitat. Relatively broad range of habitats, suggesting tolerance to fragmentation, from elevations of 75 m (Zulia, Venezuela) to 2013 m (Santander, Colombia), mostly 600-1070 m. Known localities of occurrence of the Eastern Cordilleran Nectar Bat suggest continuous distribution northward from eastern slope of Andes in Ecuador, widening in northern Colombia and north-western Venezuela. Too little is known about its ecology to fully assessits independence from old growth habitats. Other nectar-feeding bats captured at localities of the Eastern Cordilleran Nectar Bat include the Orange Nectar Bat, Pallas’s Long-tongued Bat ( Glossophaga soricina ), the Tailed Tailless Bat ( Anoura caudifer ), Geoffroy’s Tailless Bat (A. geoffroyi ), and the Broad-toothed Tailless Bat (A. latidens ), suggesting that these areas support a variety of local food resources.

Food and Feeding. No information.

Breeding. No information.

Activity patterns. Eastern Cordilleran Nectar Bats probably roost in hollow trees and small caves.

Movements, Home range and Social organization. Eastern Cordilleran Nectar Bats probably roost in small groups.

Status and Conservation. Not assessed on The IUCN Red List. Wide distribution of the Eastern Cordilleran Nectar Bat and its presence in at least a couple of protected areas in Colombia might limit human-related conservation threats.
