| Summary: | Astrotholus molginos n. gen, n. sp. FIGURE 4A–F Etymology The species epithet molginos refers to the Greek “of hide or skin” alluding to the dermis which covers the body surface of this species. Diagnosis Stellate body with R/r=1.2–2.0, abactinal plates imbricate, irregular on disk but showing strongly linear, transverse series interradially (Fig. 4A, B, D). Body surface covered by thin dermal tissue (Fig. 4D, E). Abactinal plates with 1–9, usually 2–4 short glassine spinelets with most arranged on the convex side of the imbricate plates (Fig. 4D, E), in single series interradially but in clusters elsewhere. Furrow spines 3 to 6 (at R= 2.2 cm), webbed in weakly palmate to straight series. Subambulacral spines two or three in a cluster standing apart from furrow spines, at transverse to oblique angle (Fig. 4F). Comments Astrotholus molginos n. gen. n. sp. appears to be the most morphologically dissimilar relative to the other species within Astrotholus n. gen. This is attributed to the flattened plates, as ... : 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 17-19, DOI: 10.11646/zootaxa.5310.1.1, http://zenodo.org/record/8090240 ... |
