Description
Summary:Pergamaster Koehler, 1920 Koehler, 1920: 237; Fisher, 1940: 121; A.M. Clark, 1962: 22 (key); Bernasconi, 1963: 23; H.E.S. Clark 1963: 43. Diagnosis. Body strongly stellate with elongate arms. Abactinal plates distinct, round to polygonal in outline. Abactinal and marginal plate surfaces bare, smooth. Peripheral granules, angular to polygonal-round flush with abactinal, marginal plate surfaces. Superomarginal plates abutting over midline in some individuals. Actinal surface bare or covered with angular, flattened granules. Pedicellariae absent. Comments. Two species of Pergamaster are recognized herein, including P. triseriatus from the Ross Sea and P. i n c e r t u s (with synonym P. synaptorus below), known primarily from the Weddell Quadrant. Both species show several discrete morphological differences as summarized in the diagnostic key and in descriptions herein. However, these two species are also sampled from two of the most heavily studied regions in the Southern Ocean. There is discontinuous sampling ... : 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 page 34, DOI: 10.5281/zenodo.276783 ...
