Ophiurida incertae sedis

Abyssura Belyaev & Litvinova, 1976, Anophiura H.L. Clark, 1939, Anthophiura H. L Clark, 1911, Bathylepta Belyaev & Litvinova, 1972, Haplophiura Matsumoto, 1915, Ophiochalcis Koehler, 1930, Ophiochrysis Koehler, 1904, Ophiochytra Lyman, 1880, Ophiolebella Mortensen, 1936, Ophiomaria A.H. Clark, 1916, Ophiomastus Lyman, 1878a, Ophiopenia H.L. Clark, 1911, Ophiophyllum Lyman, 1878a, Ophiotjalfa Mortensen, 1913, Ophiotrochus Lyman, 1878a, Ophiuraster H.L. Clark, 1939, Perlophiura Belyaev & Litvinova, 1972, Uriopha Paterson, 1980. (Most of these fit morphologically with Ophiopyrgidae, but in the light of their paedomorphic morphology and lack of genetic data, we refrain from placing them at this time).
