Examined species
Histampica duplicata (Lyman, 1875) View in CoL .
Oral GP
Oval scales, widely separated under OS, not visible externally.
Adradial GP
Bar-like narrow, flat shaft, distal end with condylar process and lip-like extension adradialwards, both connecting to condyles on RS. Proximal to condylar process on abradial edge a lateral process with flat surface, at adradial edge a larger flat process articulating with abGP. Distal adradial end somewhat wrench-shaped.
Abradial GP
Thin, flat, blade-like, abradial edge convex, adradial edge straight, distal end pointed. Articular structure a weakly offset distal part of adradial edge.
Oral shields
No special structures. Madreporite domed in centre with large opening.
