Removal of homonymy between Haliclona tenera (Von Marenzeller, 1878) and Haliclona tenera (Topsent, 1927).
1. Isodictya tenera Von Marenzeller, 1878: 364 (type locality South of Franz Josef Land, Arctic). Van Soest (2000: table, p. 75) assigned this species to Halichondria Fleming, 1828: 520 and listed this combination as Halichondria tenera, presumably on the basis of the large oxea size, almost 400 μm long, which is a common size in Halichondria species. However, Von Marenzeller (1878) stated he employs Isodictya as Bowerbank did in his 1866 monograph, which currently conforms largely to Haliclona Grant, 1841: 5. Hentschel (1929: 986) reassigned the species to Reniera Schmidt, 1862: 72, presumably because the skeleton is described as ‘ladder-like’, typical for Haliclona but not for Halichondria (cf. Von Marenzeller’s 1878: pl. I, figs 2, 2A). Large oxeas in Haliclona are rare but in cold water Haliclona species they are not uncommon. Accordingly, we here reassign Isodictya tenera Von Marenzeller, 1878 to Haliclona tenera, resulting in a senior secondary homonym of Topsent’s Haliclona tenera (ICZN Art. 57.3).
2. Gellius tener Topsent, 1927: 18 (type locality Azores, North Atlantic). This deep sea species has large oxeas as well, in a lax unispicular arrangement, with toxa microscleres. Originally described in the genus Gellius Gray, 1867: 538, it appears to be a typical member of Haliclona (Gellius) as defined by De Weerdt (2000: 9). Reassigned as Haliclona (Gellius) tenera it becomes a junior secondary homonym of Von Marenzeller’s species (ICZN Art. 60.3), requiring a new name.
3. Summary: Haliclona tenera (Von Marenzeller, 1878) as a senior secondary homonym is to be maintained (ICZN Art. 57.3). Haliclona (Gellius) tenera (Topsent, 1927) is a junior secondary homonym, which in the absence of synonyms, has to be renamed (ICZN Art. 60.3). To remove the homonymy Haliclona (Gellius) emilei nom.nov. was proppsed, named after Emile Topsent. [details]
