Description
Summary:Odontaster meridionalis (Smith, 1876) FIGURE 13A–E Astrogonium meridionalis Smith, 1876: 109. Pentagonaster meridionalis Smith 1879: 276. Gnathaster meridionalis Sladen 1889: 287. Odontaster meridionalis Fisher 1940: 99; A.M. Clark 1962: 15; H.E.S. Clark 1963: 34; Guille 1974: 32. Diagnosis Body weakly stellate to stellate, R/r=1.6–2.25. Disk broad, arms triangular. Interradial arcs weakly curved to straight (Fig. 13A, C). Fasciolar groove present between abactinal, marginal, actinal plates, well-developed. Abactinal surface covered by paxillate plates (Fig. 13B). Plate bases quadrilobate. Plates arranged in serial rows along arm, extending to arm tip. Each plate with spinelets, 12–25 per plate, spinelets, each with a pointed tip, spinelets largest centrally on paxillar surface. Marginal plates wide 20–28, arm tip to arm tip, quadrate, in shape, covered by 20–30 spinelets, widely spaced (Fig. 13A). Actinal plates in 5–7 chevron-like series, each plate quadrate in shape, covered by spinelets, rough, “thorny” ... : 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 page 42, DOI: 10.11646/zootaxa.5310.1.1, http://zenodo.org/record/8090240 ...
