| Summary: | Pillsburiaster calvus n. sp. (Figures 17 A–E) Diagnosis. Carinal series clearly distinguished, strongly convex, each plate with a periphery of ~20 coarse, sphaerical granules with 8–12 granules covering the plate surface (20–30 total on each plate surface). Superomarginal plates elongate with a strongly convex, round area free from granules, occupying 50–50% of each supeormarginal plate surface. Furrow spines 2–3. Body weakly stellate (R/r=1.74). Etymology. The species epithet “ calvus ” refers to the Latin for “bald” which refers to the prominent bald spots on the superomarginal plate surface. Distribution. Burdwood Bank in the Scotia Sea from 339– 357 m. Material examined. HOLOTYPE. USNM 1149357. Burdwood Bank. 54°43’S; 56°37’W to 54°42’S; 56°36’W. 339– 357 m. Coll. R/V Eltanin, University of Southern California, 14 March 1966.(1 dry spec., R=4, r=2.3). Description. Body form stellate-pentagonal (R/r=1.74). Interadial arcs concave. Arms triangular (Fig. 17 A). Abactinal plates rounded to irregular in ... : Published as part of Mah, Christopher L., 2011, Taxonomy of high-latitude Goniasteridae (Subantarctic & Antarctic): one new genus, and three new species with an overview and key to taxa, pp. 1-48 in Zootaxa 2759 on pages 41-43, DOI: 10.5281/zenodo.276783 ... |
