Distribution. NW Pacific ( 94–1250 m), W Indian Ocean ( 73–1073 m), E Indo-W Pacific ( 50–2084 m), S Africa ( 573–653 m), S Australia ( 194–256 m), New Zealand ( 376–380 m).

Remarks. The discs are 9 (IE.2023.4155) and 5.5 (IE.2016.1355) mm dd. We were unsuccessful in obtaining DNA from these samples.However,two samples from Madagascar (IE.2023.4004) and Saya de Malha(IE.2023.4202) cluster separately from East Indo-West Pacific specimens and possibly represent a cryptic species. If this western Indian Ocean clade is found to extend northwards to the Red Sea, then the name O. mabahithae ( Mortensen, 1939) is available.
