The bidentate yellow-shouldered bat (Sturnira bidens) is a species of bat in the family Phyllostomidae. It is found in South America.

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.{{cite journal|doi=10.1080/00222931508693718|url=https://biodiversitylibrary.org/page/16003941|title=XXXVI.—A new genus of phyllostome bats and a new Rhipidomys from Ecuador|journal=Annals and Magazine of Natural History|volume=16|issue=94|pages=310–312|year=1915|last1=Thomas|first1=Oldfield}} The species name "bidens" is Latin for "two teeth;" of the bidentate yellow bat, Thomas wrote, "lower incisors only two."
