Prototrochus linseae sp. nov. (S Shetland Is; RBINS IG 31 459). a, SEM of plates of the calcareous ring with prominent single anterior projections; b, SEM of wheels from the body wall. Diagnosis ( Smirnov 1998 ) . Chiridotidae with 10 or 12 tentacles. Body wall ossicles wheels of chiridotid type and sigmoid hooks or sigmoid hooks only. Radial plates of calcareous ring not perforated but sometimes slightly notched in anterior (upper) face for passage of nerves. Included genera . Archedota O’Loughlin, 2007 (in O’Loughlin and VandenSpiegel 2007 ); Kolostoneura Becher, 1909 ; Rowedota gen. nov. ; Scoliorhapis H. L. Clark, 1946 ; Sigmodota Studer, 1876 ; Taeniogyrus Semper, 1867 . Remarks . Achiridota Clark, 1908 was initially placed in Chiridotidae , but was assigned to Myriotrochidae by Smirnov (1998) on the basis of having: large anterior teeth on the plates of the calcareous ring; single polian vesicle; madreporite close to calcareous canal. Sigmodota Studer is raised out of synonymy with Taeniogyrus Semper (below). Trochodota Ludwig, 1891 is made a junior synonym of Taeniogyrus Semper (below). Scoliodotella Oguro, 1961 is made a junior synonym of Scoliorhapis H. L. Clark (below).
