The Hawaiian hoary bat (Lasiurus semotus), also known as ʻōpeʻapeʻa, is a species of bat endemic to the islands of Hawaiʻi. Whereas the mainland hoary bat (L. cinereus) is found throughout North America, the Hawaiian hoary bat is distributed only among the major volcanic islands of Hawaiʻi, making it the only extant and native terrestrial mammal in the state; although some studies also posit that the mainland hoary bat lives in sympatry on the Hawaiian Islands alongside the Hawaiian hoary bat, this has been disputed. The Hawaiian hoary bat was officially named the state land mammal of Hawaiʻi in 2015.
