Gloomy Tube-nosed Bat (Murina tenebrosa)  

This species was described in 1970 based on a single female specimen that was collected in 1962 on Tsushima, an island located in the Korea Strait, approximately halfway between the Japanese mainland and the Korean Peninsula.  

The island is badly deforested, the bat was never found again since its discovery and description, and is thus most likely extinct.
