Bathyporania ascendens n. sp. Figure 2 A–E Etymology. Species epithet ascendens (=Latin for “ascending”) refers to the in situ observation of the animal’s climb up the upper branches of a deep-sea coral, where it was collected (Fig. 2 E). Taxonomic comparison. The phylogenetic tree shown in Fig. 1, illustrates Bathyporania as sister taxon to “ Porania ” antarctica but the single individual sampled does not clarify monophyly of Bathyporania relative to “ Porania ” antarctica. Distinction of this taxon as a separate genus is based on several characters including the more densely arranged reticulate skeleton with more lobate abactinal plates, the polylobate marginal plates arranged horizontally (versus vertically in “ P.” antarctica), the absence of an actinolateral fringe of plates, the differnce in furrow spine morphology, actinal plate arrangements and differences in disk: arm ratio, including the outline of the arms. Adult size in the holotype of Bathyporania ascendens is also much smaller than those in “ ... : 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 331-333, DOI: 10.11646/zootaxa.3795.3.7, http://zenodo.org/record/252134 ...
