Distribution | Recent, Philippines and Indonesia |
Classification and/or Status | Arbacioida, Arbaciidae, Coelopleurus. |
Remarks | This species can be differentiated form all other Recent Coelopleurus by its very inflated test (slightly flattened aborally in all other Recent species), by the abundance of triphylous and tridentate pedicellariae present on the aboral surface, and by the total lack ophicephalous pedicellariae aborally. Mortensen (1934) described this species as having ocular plate 1 insert in the apical disc. This is true for the holotype, but has not been observed in five other specimens of this species that I have examined. These specimens had dicyclic apical discs typical of the genus/subgenus.
