The name of the taxon was published in a checklist by Tom Iredale and Ellis Troughton in 1934,[5] but this lacked a diagnosis and designated nomen nudum.

The taxon was published with a revised diagnosis in 2014, which separated this subgenus and Setirostris, also with a sole species (Mormopterus eleryi), from the diversity discovered in Australian molossids.

The new subgenus, later elevated to genus, Setirostris, was distinguished by the form of the corresponding upper molars, the lack of the course bristles on the face of Setirostris, and the great difference in morphology of the glans penis; phylogenic support was provided by molecular comparisons of alleles and mitochondrial DNA.

A similar diagnosis is provided to separate Ozimops, dentition, penis morphology, and the phylogenetic analysis, but notes the more evidently dome shape profile of the skull, which is significantly flattened in species of that genus.

Threats to the species may include habitat loss from timber harvesting, coastal development, and alterations of natural fire regimes.
