Hemithyone semperi

Description

Hemithyone semperi (Bell, 1884)

Material examined. Northwest Western Australia, Kimberley Region, Camden Sound, WAMSI 1.1.1, RV Solander, sled, site no SOL_56, WAM station no 20, barcode 10001531, from -15.376537 124.192773 35 m to -15.376196 124.192071 35 m, 19 Mar 2015, WAM Z89055 (1).

Remarks. We have retained Hemithyone semperi (Bell, 1884) in family Thyonidae and subfamily Thyoninae, but with major reservations. The species does have a composite calcareous ring, but the tube feet are radial and the species lacks table and cup ossicles and has predominantly very open fenestrated ellipsoids in the body wall. Smirnov (2012) remarked “it is possible that Hemithyone Pawson, 1963 does not belong to Thyonidae ”. We await generic evidence for a review of its higher taxon referral.
