Macroderma koppa is a species of bat known from fossil material found in Australia, one of the larger carnivorous megadermatid family of the order Chiroptera.

The type locality, described as Big Sink, is one of several sites containing fossil depositions in the cave system, a complex assemblage that contains a variety of vertebrate species.

The author's specimens were designated as a holotype, a skull with complete dentition, and paratype material exhibiting other distinguishable characters.

The period of deposition for the fossil material has been verified by correlation to dating of the Riversleigh sites, where other megadermatid species are recorded.

The bones of Macroderma koppa are well represented at this site, with evidence of their consumption of prey, suggesting the cave was occupied by the population as a maternity colony and feeding roost.
