Abactinal paxillae abundant, close-set, each with 15–30, usually 20–30 spinelets, these forming a close-set canopy over the abactinal surface giving a hirsute appearance (Fig. 19A, B). Paxillar base with four lobes. Superomarginals alternate with inferomarginals, similar but larger than adjacent abactinals, approximately 10–18 spinelets, thick, capping each plate (Fig. 19B). Inferomarginals 20 per arm side, larger than superomarginals, approximately 10–18 spinelets, blunt, thick (Fig. 19C). Actinal interradial region with three chevrons of plates, each with spines, 1–9, variably showing higher numbers proximally then decreasing distally. Furrow spines 2–5 with highest number proximally (Fig. 19D). Subambulacral spines, 4–5 in ... : 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 60-62, DOI: 10.11646/zootaxa.5310.1.1, http://zenodo.org/record/8090240 ...
