Sclerothyone oloughlini Martins & Tavares, 2019

Martins & Tavares’ (2019) referral of this species to Sclerothyone is here questioned as the calcareous ring appears to be of the Sclerodactylid type. However, since the tube feet are restricted to the ambulacra and the tables have a handle on one side, it is here left to stand in Sclerothyone as intermediate forms are to be expected.
