| Summary: | Glabraster A.H. Clark 1916 Figure 5 A–F Glabraster A.H. Clark 1916: 122 Type species: Porania magellanica Studer 1876 (a synoym of Porania antarctica Smith 1876) Diagnosis. Body weakly pentagonal to strongly stellate (R/r= 1.51–2.85). Arms, triangular in shape, varying from well-developed and elongate, contiguous with body to short and emerging abruptly from well-developed disk. Body generally tumescent. Prominent skin overlying abactinal, marginal and actinal surfaces. Plate outlines obscured in wet specimens. Abactinal plates forming widely-spaced, reticulate pattern. Skin present between widely reticulate plates bearing small ossicles among many of the open spaces. Spines present or absent on abactinal plates. When present, spines are prominent and present individually on each plate. Spines, short with thorn-like or blunt tips tend to be most prominent on plates where confluences of bands are present but they are also present in several individuals on individual abactinal bands. Marginal plates imbricate, ... : 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 338-339, DOI: 10.11646/zootaxa.3795.3.7, http://zenodo.org/record/252134 ... |
