Taxonomy and etymology
It was described as a new species in 1915 by British zoologist Oldfield Thomas. The holotype had been collected by Walter Goodfellow in April 1914 in Baeza, Ecuador. Thomas described a new, now-defunct genus, Corvira, giving the species the binomial of Corvira bidens.[2] The species name "bidens" is Latin for "two teeth;" of the bidentate yellow bat, Thomas wrote, "lower incisors only two."[2]
Description
It has a forearm length of 39.3–43.3 mm (1.55–1.70 in). It has a long and narrow snout and an overall narrow skull. It has a dental formula of 2.1.2.31.1.2.3 for a total of 30 teeth.[3]
Range and habitat
Its range includes Peru, Ecuador, Colombia, and Venezuela. It is found in association with the Andes Mountains at elevations of 1,700–3,000 m (5,600–9,800 ft).[1]
Conservation
As of 2018, it is evaluated as a least-concern species by the IUCN, which is its lowest conservation priority. It has a wide geographic range; its population is presumably large; and it is unlikely to be experiencing rapid population decline. Its population is not severely fragmented, and its population trend is projected as stable.[1]
