The species was first proposed as a subgeneric arrangement of Nyctimene, published as Nyctimene (Paranyctimene) tenax.[2] The epithet tenax, derived from the Latin for 'steadfast', was intended to describe the conservation work of Peter Nijhoff, whose retirement was announced when the new species was discovered.[2] The subspecific epithet marculus, derived from Latin, translates as 'little hammer' and the diminutive form of Marc Argeloo's name, a dedication to his collections of bats for the Amsterdam Zoological Museum. Two subspecies were recognised by Mammal Species of the World (2005).[3]
Paranyctimene
Paranyctimene raptor (Lesser tube-nosed fruit bat), the type, first proposed in 1942.
Paranyctimene tenax Bergmans, 2001[2] (Steadfast tube-nosed fruit bat)
The species is larger than Paranyctimene raptor, with recorded forearm measurements of 51.0 to 54.9 millimetres, and the greatest length of the skull in a range of 25.2–27.2 mm for both subspecies. [2]
