| Summary: | Paralophaster paucispinus n. sp. FIGURE 23 A–F Etymology The species epithet paucispinus is Latin for “few or little spines” alluding to the relatively few spines on the abactinal paxillae and the furrow spines. Diagnosis Body form stellate with broad disk, triangular arms (R/r=2.0), interradial arcs weakly curved (Fig. 23A, E). Abactinal paxillae with two to four spinelets (Fig. 23B). Disk broad with interradial regions divided by lobate plates (Fig. 23A, C). Marginal plates, only one row discernable, 26–28 per interradius (13–14 per arm side) (Fig. 23, D, E). Each marginal paxillae with 4–10 blunt spinelets. Furrow spines two proximally then one distally, subambulacral spines, two, widely spaced, lacking serrated shaft (Fig 23F). Comments Paralophaster paucispinus n. sp. is distinguished from other Paralophaster species by presence of significantly few spinelets on abactinal and marginal paxillae, as well as for low numbers of furrow and subambulacral spines. Paralophaster paucispinus is one of three ... : 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 69-71, DOI: 10.11646/zootaxa.5310.1.1, http://zenodo.org/record/8090240 ... |
