Diagnosis
As for Ophiopsilidae stat. nov.
Family Ophiopsilidae Matsumoto, 1915 stat. nov. (raised to family rank)
Type genus
Ophiopsila Forbes, 1843 (type species: O. aranea Forbes, 1843 ).
Diagnosis Dorsal disc fully scaled, neither spines nor granules. Extremely long, flat tentacle scales that cross on the mid-line of the ventral arm. Ventral tooth sockets shallow and indistinct, dorsalwards increasing in size and penetrating with septum. Oral plate (half-jaw) higher than long, with large dorsodistal muscle flange (similar to Amphiuridae ). Arm spine articulations with two smooth, parallel, straight lobes, in the proximal space between them a short ridge (similar to Amphilimna ). Inner side of lateral arm plates with two merged knobs instead of a ridge.
Remarks
The position of this family is variable in our molecular analyses with some trees supporting a sister relationship to the Ophionereidina and others to the Gnathophiurina ( O’Hara et al. 2017) . The morphological analysis supports a relationship within Gnathophiurina , close to Amphiuridea (Thuy & Stöhr 2016).
