Toxochalina multiformis Pulitzer-Finali, 1986

Toxochalina multiformis Pulitzer-Finali, 1986: 175, fig. 84.

Currently, Toxochalina Ridley (1884: 402) is considered a subgenus of Callyspongia Duchassaing & Michelotti, 1864 (see e.g. Desqueyroux-Faúndez & Valentine, 2002a: 844). The present combination, described by Pulitzer-Finali from La Parguera, Puerto Rico, approximate coordinates 17.9494°N 66.9069°W, depth 2 m (holotype MSNG 47710), is a junior secondary homonym of Ceraochalina multiformis Von Lendenfeld (1887: 783), as this was reassigned to the genus Callyspongia by Burton (1934a: 607) (followed by Hooper & Wiedenmayer 1994: 98). Von Lendenfeld described six varieties of C. multiformis, the first of which, var. maeandra, is here chosen as the nominotypical variety to be named Ceraochalina multiformis var. multiformis (cf. ICZN art. 47.1), described from Port Chalmers, New Zealand, approximate coordinates 45.825°S 170.6083°E (dried holotype BMNH 1886.8.27.426, fide Hooper & Wiedenmayer, 1994: 98). Despite the fact that C. multiformis Von Lendenfeld is currently considered a junior synonym of Callyspongia (Callyspongia) nuda (Ridley, 1884: 395), cf. Van Soest et al. 2020: 38, the junior name must be replaced as both senior and junior name belong to the same genus (ICZN art. 59.1). I propose Callyspongia (Toxochalina) gustavoi nom.nov., named after Gustavo Pulitzer-Finali.
