Miniopteridae Dobson, 1875

Miniopterus sp. cf. australis Tomes, 1858 . Recorded from Sumatra eastwards to Borneo, New Guinea, Australia and as far east as Vanuatu and New Caledonia, this widespread species has previously been reported from Batanta and Waigeo in the Raja Ampat group and nearby Gebe in the North Moluccas ( Flannery, 1995; Meinig, 2002; Armstrong et al., 2021). Frequency modulated calls with a characteristic frequency of ca. 53 kHz and a terminal droop have been attributed to small species of bent-winged bat in Papua New Guinea (call type 53 st.cFM.d) ( Fig. 3 ). The revision of Indo-Australasian Miniopterus by authors SW and KNA did not include a sample from Kofiau Island, but this call type is likely attributable to an undescribed species of small Miniopterus .
