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. 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 ... : Published as part of Mah, Christopher L. & Foltz, David W., 2014, New taxa and taxonomic revisions to the Poraniidae (Valvatacea; Asteroidea) with Comments on Feeding Biology, pp. 327-372 in Zootaxa 3795 (3) on pages 335-337, DOI: 10.11646/zootaxa.3795.3.7, http://zenodo.org/record/252134 ...
