| Summary: | Kampylaster Koehler, 1920 Koehler, 1920: 136, Fisher 1940: 250; Bernasconi 1973a: 344; A.M. Clark 1993: 220; O’Loughlin & Waters 2004: 22. Diagnosis Arms five. Body thick, pentagonal to weakly stellate (R/r=1.0–2.2), strongly arched (dome-shaped). Abactinal surface composed of imbricate flattened to weakly convex plates, larger plates proximally becoming smaller distally. Abactinal and marginal plates covered by round to cylindrical/bullet-shaped granules, evenly distributed over abactinal and lateral surface covering boundaries between plates. Marginal plates forming crenulate margin. Actinal surface with one to three short, blunt spinelets. Furrow spines, 2 to 5 in transverse series. Superambulacrals and superactinal plates absent. Comments Kampylaster has received little discussion since its description (Koehler 1920), which seems largely due to its lack of shared characters with other members of the Asterinidae, including internal skeletal ossicles such as the superambulacrals and superactinals ... : 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 22, DOI: 10.11646/zootaxa.5310.1.1, http://zenodo.org/record/8090240 ... |
