Examined species
Ophiopus arcticus View in CoL .
Oral GP
Absent.
Adradial GP
Wrench-shaped adradio-dorsal distal end, single flat distal condyle bordered by groove, separated from round process by deep incision, process finer meshed on adradial side. Proximal half bar-like, with longitudinal groove in abradial surface. On abradial side a longitudinal groove.
Abradial GP
Absent.
Oral shields
Inner side in distal half laterally thinner with smoother, finer porous stereom. Madreporite inner side with large centrodistal opening.
Radial shield
Articular structure a low condyle and groove, large round patch of finer stereom proximal to condyle.
Remarks
Ophiopus arcticus lacks genital slits, which may explain the absence of oral GP and abradial GP.
