Thyone Oken, 1815

Diagnosis (emended from Pawson and Miller 1981). Tentacles 10; tube feet scattered on body wall, never restricted to radii; calcareous ring tubular with long posterior prolongations comprising a mosaic of small pieces; body wall ossicles tables with a spire of one or two pillars.

Type species. Holothuria fusus Müller, 1776 (monotypy).

Southern Australian species. Thyone flindersi O’Loughlin sp. nov.; Thyone joshuai O’Loughlin , sp. nov.; Thyone kerkosa O’Loughlin sp. nov.; Thyone nigra Joshua and Creed, 1915 ; Thyone okeni Bell, 1884 ; Thyone spenceri O’Loughlin sp. nov.; Thyone tourvillei O’Loughlin sp. nov.

Remarks. We acknowledge the current invalid status of Thyone Oken, 1815 and our provisional retention is discussed in the Introduction. We emend the diagnosis of Thyone Oken to include tables with one pillar in the spire to accommodate a new species described in this work. Pawson and Miller 1981 remarked on the need for a revision of the “supergenus” Thyone . This need continues for what will be a major undertaking. The revision should await further supportive evidence from emerging genetic data.
