'', both taxa emerging in the publication of new species and generic combinations of mostly Australian

bats. Prior to this, an analysis of populations in the regions in 1988 had identified this group as ''Mormopterus'' species 5 (populations S and T)'. Specimens have previously been described as '' Mormopterus ridei'', at least in part, or other uncertainty in paraphyletic groups once referred to as the ''planiceps'' complex. The generic combination of this species was inferred by the elevation of a subgenus to genus ''Ozimops''. The first publication of the species was in 2014, allying it to a subgenus of the group under revision as ''Mormopterus'' (''Ozimops'') ''halli''. The common names also include Cape York free-tailed bat. The

Distribution and habitat

The records for ''Ozimops halli'', which number around a dozen, are in separate localities in the north of Queensland. The known records are separated by around 500 kilometres, in a region poorly surveyed for bat populations, and it may be widespread or occur in isolated colonies. The established range is within or nearby to the type location, the conservation area Oyala Thumotang NP. Surveys of the distribution range would be assisted by analysis of the characteristics of the species echolocation call. The species is known from specimens captured by
