Eumops delticus is a species of free-tailed bat found in South America.[1]
Taxonomy
Eumops delticus was described as a new species in 1923 by British mammalogist Oldfield Thomas.[2]
The holotype had been collected by Wilhelm Ehrhardt (1860–1936), a Guyana-born German animal collector.
The type locality was the Brazilian island of Marajó.[3]
In 1932, Colin Campbell Sanborn published that E. delticus should be considered a subspecies of the dwarf bonneted bat (E. bonariensis).[4]
It was generally regarded as a subspecies until 2008 when Eger et al. published it as its own species again.[1][4]
Description
Based on the holotype, E. delticus individuals have a forearm length of around 47 mm (1.9 in), a head and body length of 68 mm (2.7 in), and a tail length of 41 mm (1.6 in).[5]
Range and habitat
E. delticus is found in the following South American countries: Brazil, Colombia, and Peru.[1]
Conservation
As of 2018, it is evaluated as a data deficient species by the IUCN.
It meets the criteria for this classification because of ongoing uncertainty of its geographic range and ecological requirements.[1]
