Diagnosis
ReferenceDiagnosis
H. Hess and C. A. Meyer 2008Disk covered with small scales, overlain on both sides by dense granulation that does not cover the oral shields, except in Aplocoma brevispina; adoral shields barely to widely in contact; radial shields small; mouth armature of contiguous row of oral papillae and mostly small, conical to flattened teeths; oral frame without wings; second tentacle pore facing into mouth opening; arms long, slender and flexible, lateral plates flat or bent, not swollen; arm spines mostly few, short and adpressed or longer and erect; dorsal and ventral arm plates contiguous over most of the arms; two leaf-like tentacle scales, genital scale broad and flat, genital plate bar-like to club-shaped.
