LIVING AUSTRALIAN SPECIES OF THE ECHINOID PERICOSMUS (SPATANGOIDA PERICOSMIDAE)

WA Museum Records and Supplements | Updated 1 decade ago

Abstract
Three species of Pericosmus are described from Australian waters. P. porphyrocardius sp. nov. is described on the basis of a suite of specimens from the North-West Shelf and one specimen from north-east Queensland. The two other described species are each only known from single specimens and are placed in open nomenclature. Both were collected from waters off the Queensland coast. The phylogenetic significance of the variability of the adoral plating in P. porphyrocardius is discussed.
