These include total skull length, from the posteriormost point of the occiput to the anteriormost point of the premaxillae; condylobasal length, a line connecting the posterior margins of the occipital condyles to the anteriormost point of the premaxillae; zygomatic breadth, greatest breadth across the zygomatic arches; postorbital breadth, least breadth across the frontals posterior to the postorbital process; braincase breadth, greatest breadth of the globular part of the braincase; palatal length, from the posteriormost margin of the upper medial incisor alveolus to the posteriormost point of the palate (including the postpalatal spine, when present); maxillary tooth-row length, from the anteriormost face of the canine to the posteriormost face of the crown of the 3rd molar; mandible length, from the anteriormost point of the mandible to the posteriormost point of the mandibular condyle; mandibular tooth-row length, from the anteriormost face of the canine to the posteriormost face of the 3rd molar; breadth across molars, greatest breadth across the outer edges of the crowns of the 3rd upper molars; and breadth across canines, greatest breadth across the outer edges of the crowns of the upper canines. (original number CM009), on the Condor Mirador (near the Destacamento Militar; 3°38′08″S, 78°23′22″W) of the Cordillera del Condor, 1,750 m, Zamora Chinchipe Province, Ecuador. 2) and an extremely long tongue (6–8 cm in fresh individuals)..— Adult male (EPN 9713), preserved in alcohol with skull removed (Fig. The interfemoral membrane is relatively wide (3.3–7.5 mm) with an inverted V-shaped margin (versus narrow and U-shaped in other (Table 1).Color of skin of ears, noseleaf, tragus, wings, and interfemoral membrane Sepia (219).Cranium and mandibles similar in shape to those of , the lower lip extends only slightly beyond the upper lip (less than 1 mm) and has a V-shaped pattern of papillae on the lip margin, which is oriented vertically as seen in the frontal view of the head. , the lip is elongated (4–6 mm beyond upper lip) and rolled into a tube, with the papillae forming a fringe along each margin of the dorsal slit in the tube (Fig. The only other glosso-phagine with a similar development of the lower lip is is larger on average by approximately 10%, ranges of some measurements overlap (Table 1), and both species have tails and comparatively wide uropatagia.Lower lip elongated, extending 3.3–4.8 mm anterior to the upper lip, and rolled into a tubelike structure that is slit dorsally (Fig. Margins of this protrudent lower lip adorned with small tubercles.Tongue extremely long; 6–8 cm, as measured from fresh specimens in the field.
Ha sido colectado infrecuentemente en los bosques nublados de ambos lados de los Andes de Ecuador, donde co-ocurre con los mas abundantes are distributed from central Mexico to Bolivia, with the highest abundance and diversity in the Andes of South America (Barquez et al. The genus includes 5 recognized species: is rare in Ecuador; the few known specimens come from the slopes of the Andes from 50 up to 2,200 m.
Mass was taken in the field with a Pesola scale (Pesola AG, Baar, Switzerland) and rounded to the nearest 0.5 g.
