| Summary: | Chitonaster trangae n. sp. (Figure 7 A–F) Mein, 1992: 245; Stampanato & Jangoux, 1993: 181. (as C. johannae) Diagnosis. Papulae present between abactinal plates. Blunt, cylindrical spines on abactinal and marginal plates. Granules coarse and well-spaced. Abactinal plates larger than in other known Chitonaster species (C. cataphractus, C. felli, and C. johannae). Etymology. This species is named for Trang Ngyuen, US Antarctic Research Program for her enthusiasm and diligent contributions to the study of Antarctic marine invertebrates. Distribution. Palmer Archipelago, Antarctic Peninsula, Vahsel Bay, Weddell Sea, South Orkney Islands, Scotia Sea, South Shetland Islands, Bransfield Strait, Off Enderby Land. 104–412 m depth. Distinctions from other species. Chitonaster trangae n. sp. occurs primarily in shallow-water settings (100– 400 m). It is distinguished primarily by the presence of papulae on the disk (papulae are absent in the deep-water taxa), the larger, coarser, and more widely-spaced surface ... : 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 17-19, DOI: 10.5281/zenodo.276783 ... |
