Description
Summary:Solaster hexactis sp. nov. Figures 1 –7 Type locality: Alaska, Aleutian Islands, W of Buldir Island (52° 18.50 N, 175° 49.00 E), 325 m. Type material. Table 1. Description. Small six-rayed form, Holotype, R = 41 mm, r = 15 mm. R: r = 1:2.7 (range 1:1.7 to 1:2.7); disc relatively small, rays moderately long, tapering to rather blunt tips. Dorsal side (Fig. 1) moderately inflated. Papular pores numerous, small, occurring singularly or in pairs; papulae rather small. Abactinal plates cruciform, imbricating; Pseudopaxillae relatively large, bearing 20–40 spinelets with thorny tips; Madreporite very small, only about twice as large as pseudopaxillae, radially grooved, surrounded and obscured by six pseudopaxillae (Fig. 2). Superomarginals only slightly larger than aboral pseudopaxillae. Inferomarginal plates about three to four times as wide as long, spaced about one half length apart, and usually slightly off set from the adjacent supramarginal; fan shaped, bearing about 50+ spinelets. Ventral side flattened; ... : Published as part of Clark, Roger N. & Jewett, Stephen C., 2011, Three new sea stars (Asteroidea: Solasteridae & Pterasteridae) from the Aleutian Islands, pp. 1-13 in Zootaxa 3051 on pages 2-5, DOI: 10.5281/zenodo.202819 ...
