| Summary: | Paralophaster ferax n. sp. FIGURE 20A–F Etymology The species epithet ferax is Latin for fertile or fruitful, alluding to the brooding behavior found in this species. Diagnosis Body shape weakly stellate (R/r=1.7), arms short, triangular, disk large (Fig. 20A, C). Body thickened. Interradial arcs weakly curved. Largest R= 2.5 cm. Abactinal plates paxillate, each with spines, 10–25, each bearing pointed, jagged hyaline tips (Fig. 20B). Plates separated by membranous skin. Marginal plates 26–28 per interradius (13–14 per arm), widely spaced, single series of marginals observed, superomarginals not clearly discerned, these either weakly expressed or irregular. Marginal plates are large, paxillate with trunk-like shaft, head of paxilla with curved head, each bearing spines, 8–30 on plate surface. Actinal region small, with 1–4 small, round plates, each bearing 1–3 spinelets. Furrow spines, 2–4, palmate arrangement with basal webbing (Fig. 20F). Subambulacral spines two, decreasing to a single spine distally ... : 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 62-64, DOI: 10.11646/zootaxa.5310.1.1, http://zenodo.org/record/8090240 ... |
