Description and characteristics

Species in this genus are distinguished from other Echinothuriidae by their lack of ophicephalous pedicellariae (despite presence of dactylous ones), and the presence of prominent membranous gaps along horizontal sutures in interambulacral zones of both oral and aboral surfaces.[2]

Taxonomy

The World Echinoidea Database recognises these species:[1]

"†" means an extinct taxon.

gollark: I have notes (on academic topics) because I can *generally* remember stuff fine but sometimes forget a thing and require some information on it rapidly || 🐝.
gollark: That is not how "extensively" works.
gollark: (and then just caching that after parsing it on save, obviously)
gollark: Minoteaur will do so by traversing cmark ASTs and applying accursed regexes..
gollark: I think Roam has that too (although probably better, as they actually work on it full time and know what they're doing and made some different architectural decisions).
