Poecillastra compressa var. parvistellata Topsent, 1913: 611 Cárdenas & Rapp 2012: 28 Correcting sponge names: nomenclatural update of lower taxa level Porifera Van Soest, Rob W. M. Zootaxa 2024 2024-01-09 5398 1 1 122 7MH7K Topsent, 1913 Topsent 1913 [151,818,1040,1067] Demospongiae Vulcanellidae Poecillastra Animalia Tetractinellida 58 59 Porifera variety compressa parvistellata  ( Figs. 6F–G)      Poecillastra compressavar. parvistellata Topsent, 1913: 611, pl. IV figs. 1–2;  Cárdenas & Rapp 2012: 28, table 4.  The variety was erected by Topsent for four fragments of a single specimen, collected by the Scottish National Antarctic Expedition, Stat. 461, off Gough Island, South Atlantic, 40.3333°S 9.9417°W, depth 183 m( holotypeRoyal Scottish Museum, RSM.1921.143.1394). It resembles the typical variety  Ecionemia compressa Bowerbank (1866: 55, from Shetland, approximate coordinates 60.4667°N 1.0°W, depth 201m, holotypeBMNH BK353-354) and many other  Poecillastra compressaspecimens from the North Atlantic in shape and spicules, but the plesiasters of the present variety are smaller (and rare), 16–13 µm vs. 52 µm in the typical variety, and the spiraster/metasters are also small, 10–13 vs. 20 µm. Cárdenas & Rapp (2012)were not certain of the status of the var. parvistellata, but in view of the allopatric occurrence I propose to elevate the variety to subspecies, to be named  Poecillastra compressasubsp. parvistellata Topsent, 1913.
