Prototrochus
Belyaev and Mironov, 1982
Diagnosis (after
Gage and Billett 1986
)
. Myriotrochid with 10 tentacles; calcareous ring symmetrical, with dorsal and ventral plates subequal in size; dorsolateral radial plates with single anterior projection; wheels with teeth distributed regularly, pointing towards centre of hub; rods absent from body wall, sometime occurring in and around tentacles.
Remarks
.
Belyaev and Mironov (1982)
noted in erecting their new genus
Prototrochus
that the wheels of their included species
Prototrochus bipartitodentatus
(
Belyaev and Mironov, 1978
)
were exceptional within their diagnosis as there are small external teeth at the base of the internal teeth.
