Temminck’s Mysterious Bat

Nycticeius aenobarbus

French: Nycticée a barbe rousse / German: Temminck-Neuweltabendsegler / Spanish: Nicticeo de barba roja

Taxonomy. Vespertilio aenobarbus Temminck, 1840,

“I’Amérique méridionale.”

Nycticerus aenobarbus was originally placed in Vespertilio and later considered a synonym of Myotis albescens . Nevertheless, the type specimen was considered specifically and generically distinct and later placed in Nycticerus. Status of Temminck’s Mysterious Batis still uncertain, and dubious type locality could directly influenceits systematic status. If type material is from the Old World, N. aenobarbus could be related to Scotoecus, Scotorepens, or Scoteanax . Monotypic.

Distribution. Unknown; according to type locality, it occurs in South America, but this information is dubious.
