| Summary: | Notioceramus neillae n. sp. FIGURE 11A–F Etymology The species epithet is named for Ms. Kate Neill, echinoderm researcher at the New Zealand Institute of Water and Atmosphere who has been instrumental in repatriation of US Antarctic Research Program specimens to the NMNH. Diagnosis Body stellate, arms tapering, triangular (Fig. 11A). Superomarginal plates with bald spot, variably small (<25% of total surface) to near entirety of plate surface (Fig. 11B, C, D). Superomarginal plates form distinct convex curvature onto lateral abactinal surface. Furrow spines two or three (Fig. 11F). Comments This is a second deep-water Notioceramus species, which appears to share more characters in common with Notioceramus anomalus. This latter, shallower species displays smooth, spherical granules on the abactinal and marginal plates as well as on the tips of actinal spines; in contrast, arms of Notioceramus neillae n. sp. are less robust and granules only finely spinose. Granules and actinal spination more weakly ... : Published as part of Mah, Christopher L., 2023, New Genera, Species, and observations on the biology of Antarctic Valvatida (Asteroidea), pp. 1-88 in Zootaxa 5310 (1) on pages 37-39, DOI: 10.11646/zootaxa.5310.1.1, http://zenodo.org/record/8090240 ... |
