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]
