Family Ophiotomidae Paterson, 1985 View in CoL stat. nov.

Ophiotretidae O’Hara et al., 2017: 421, figs 1–2 (nomen nudum).

Type genus

Ophiotoma Lyman, 1883 (type species: O. coriacea Lyman, 1883 ).

Other genera

Ophiocomina Koehler in Mortensen, 1920 , Ophiocopa Lyman, 1883 , Ophiomitra Lyman, 1869 , Ophiopristis Verrill, 1899a , Ophiotreta Verrill, 1899a .

Diagnosis

Dorsal disc with granules or long, thorny spines. Abradial genital plate with concave adradio-distal tip. Arm spines flattened, laterally serrated. Dental plate fragmented ( Ophiotreta , Ophiocopa ) or entire ( Ophiocomina , Ophiotoma ), sockets shallow. Ventral clusters of short, papilliform teeth in Ophiotreta and Ophiocomina . Arm spine articulation lobes with small perforations or imperforate. Ridge on the inner side of the lateral arm plates with two kinks and a ventro-proximalwards pointing projection associated with the dorsal kink. This family was mistakenly named Ophiotretidae in O’Hara et al. (2017).

Remarks

The species Ophiocomina australis H.L. Clark, 1928 is a Clarkcoma species (Naughton et al. 2014; O’Hara et al. 2017), which leaves Ophiocomina monotypic. Ophiotoma is polyphyletic ( O’Hara et al. 2017).
