Material examined. Australia. WA. Leveque L 27 transect (15°00.52'S – 14°59.05'S, 121°38.08'E –121° 39°10'E), 205–211 m, 25 Jun 2007 (stn SS05/2007 099), NMV J58221 (2 females 11.7 x 9.7 mm, 11.8 x 10.1 mm; juvenile 5 x 3.9 mm) .

Remarks. These specimens from the northern part of the Western Australian continental slope fit well with the description of O. luzonicum from the Philippines. These records extend the distribution of the species considerably south, to 15°S in the western Indian Ocean. The species’ distribution does not overlap with that of another Oxypleurodon from the southern part of the Western Australian slope which is described below as a new species.
