Clavaporania fitchorum nov. sp. Figure 3 A–F Etymology. The species epithet is named for Mason and Lisa Fitch, for their support of academic endeavors. Taxonomic notes. This species is only the second recognized poraniid from the Macquarie Island region and the first from such the upper bathyal zone...

Figure 3 A–F Etymology. The species epithet is named for Mason and Lisa Fitch, for their support of academic endeavors. Taxonomic notes. This species is only the second recognized poraniid from the Macquarie Island region and the first from such the upper bathyal zone. O’Hara (1999) recognized “ Porania ” antarctica from 13–105 m depth. “P.” antarctica lacks the covering of spinelets on the body surface, the well-developed spines on the abactinal and marginal surface and the strongly stellate body. Clavaporania shares a reticulate abactinal skeleton with Bathyporania, “ P. antarctica, and Poraniopsis. Large primary spines are present in all known species of Bathyporania and Poraniopsis but not in all species of “P.” antarctica. Given the more distant phylogenetic position of Poraniopsis, it is unclear if the skeleton and spines are shared plesiomorphies or derived characters in Clavaporania. Occurrence. South of Macquarie Island, 1574–1693 m. Description. Body shape, strongly stellate (R/r= 5.4), Arms round in cross-section, disk small (Fig. 3 A). Pedicellariae not observed. Abactinal skeleton densely reticulate, embedded in a thick, fleshy skin. Skeleton composed of larger, reticulate ossicles and smaller, secondary ossicles distributed throughout. Single papular pores. Open papular meshes absent. Abactinal and marginal spines are strongly clavate, almost mace-like, with blunt, but finely notched to irregular tips (Figs. 3 D, F).
