Darien Broad-nosed Bat Platyriunus aquilus French: Sténoderme du Darien / German: Darien-Breitnasenfledermaus / Spanish: Platirrino de Darién Taxonomy. Vampyrops aquilus Handley & Ferris, 1972 , “on the head of the Rio Pucro, 4,100 fi. [= 1250 m ], Cerro Mall, Darién , Panama .” Platyrrhinus aquilus was confused with P. dorsalis and P. umbratus prior to its morphological distinction. Phylogenetic analysis confirmed its relationships to the P. dorsalis species group. Monotypic. Distribution. Endemic to SE Panama ( Darién Province ); probably also in nearby NW Choco Department of Colombia . Descriptive notes. Head-body 70-78 mm (tailless), ear 19-20 mm, hindfoot 10-8-12-3 mm, forearm 45-2-46-8 mm; weight 16-20 g. The Darien Broad-nosed Bat is medium-sized. Dorsal fur is bright blackish brown; ventral fur is dense, pale brown and gray; and dorsal and ventral hairs have three bands (individual dorsal hairs: 8-10 mm, bases dark brown, poorly differentiated from tips). Supraocular and subocular facial stripes are the same color (whitish hairs with dusky tips). Dorsal stripe is very sharply defined and brighter than facial stripes. Proximal one-half of forearm and to a lesser extent dorsal parts of legs are densely covered with long hairs. Tail membrane is very short, hairy on both surfaces, with U-shaped margin densely fringed with long dark hairs. I' are short, with straight outer edges, convergent, and distally in contact. P* have large posterocingular cusps; M' metastyle is present, and protocone is moderately developed. Stylid cuspulid is absent on anterior and posterior cristid of P,. Habitat. Only known from surroundings near Cerro Mali and Cerro Pirre in south-eastern Panama ; both areas are dominated by cloud forests at elevations of 1250-1433 m. Food and Feeding. Because of its overall similarity to the Shadowy Broad-nosed Bat ( P. umbratus ) and other medium-sized species of Platyrrhinus , the Darien Broad-nosed Bat is expected to be frugivorous. Breeding. No information. Activity patterns. No information. Movements, Home range and Social organization. No information. Status and Conservation. Classified as Data Deficient on The IUCN Red List. There is limited knowledge about population status and ecology of the Darien Broad-nosed Bat. Bibliography.
