Genus Paroriza Hérouard, 1902 View in CoL
Diagnosis (see Hérouard, 1902)
Remarks. Paroriza was moved to family Gephyrothuriidae by Miller et al. (2017) as a well-supported sister to Gephyrothuria alcocki , the type-taxon of Gephyrothuriidae . The morphology of the genus differs from the family diagnosis in that only the midventral is completely bare, not the ventrolateral radii. This description also excludes some smaller specimens that have since been noted to have a complete covering of tube feet (Hansen, 1956). There are four currently accepted species worldwide: Paroriza grevei Hansen, 1956 , P. pallens ( Koehler, 1895) , P. prouhoi Hérouard, 1902 and P. verrucosa Massin, 1987 . Here we report one lot of P. prouhoi from the IOT at a single station, the first species-level record for the genus in Australia (ALA, 2024). Paroriza is most easily distinguished from Gephyrothuria by being crowded with dorsal appendages rather than having only a few on the dorsal radii, and by being ventrally flattened rather than rounded with a tail ( Gephyrothuria has a similar shape to Molpadiidae ).
