Myotis oreias (Temminck)

Singapore Whiskered Bat (Myotis oreias 

The Singapore Whiskered Bat was described in the year 1840.  

The species, however, is known only from the type, which, moreover, is damaged, furthermore it is quite impossible that a bat species should be restricted to such a small region as Singapore.  


The ‘species’ thus is mentioned here only for the sake of completeness.

Myotis diminutus Moratelli & Wilson

Small Whiskered Bat (Myotis diminutus)

This species was described in 2011 and was originally known only from the type, a subadult individual that had been collected in 1979 in a fragment of moist forest on the western slopes of the Ecuadorian Andes.

A second specimen, discovered some years later in a museum collection was collected in 1959 at La Guayacana in western Colombia. 

The Small Whiskered Bat apparently is/was restricted to the so-called Chocó ecoregion, lowland forest areas that now are mostly deforested, and is probably extinct. [1]

Pipistrellus sturdeei Thomas

Sturdee’s pipistrelle (Pipistrellus sturdeei)  

Sturdee’s Pipistrelle was described in 1915 and so far, is only known from the type specimen that was collected at an unknown location sometime at the end of the 19th century.  

Some sources cite Hahajima in the Ogasawara Archipelago, Japan, as the location of the species, but that seems to be a mistake.  


The taxonomic status of the animal is actually not entirely clear either.

Murina tenebrosa Yoshiyuki

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.
