Abstract

A new species of coelacanth, Whiteia oishii sp. nov. is described on the basis of complete specimens from West Timor in Indonesia. This species differs from other species in the genus Whiteia by the presence of five to ten long ridges on scales, nine rays on the first dorsal fin, pointed denticles on the anterior fin rays of the first dorsal fin, and an operculum ornamented with many tubercles. Whiteia oishii sp. nov. is the first coelacanth occurrence from Southeast Asia and its discovery sheds light on the worldwide distribution of the genus Whiteia in the marine Triassic.
