Removal of homonymy between Myxilla (Styloptilon) ancoratum (Cabioch, 1968) and Myxilla (Styloptilon) anchorata (Bergquist & Fromont, 1988).
1. Styloptilon ancoratum Cabioch, 1968: 236–239 (type locality Brittany, Atlantic coast of France). Originally described as Styloptilon ancoratum Cabioch, 1968 this species was transferred to Myxilla through the synonymy of Styloptilon Cabioch, 1968 with Myxilla Schmidt, 1862 used as a subgenus of the latter (Desqueyroux-Faúndez & Van Soest 1996: 26), differing from Myxilla (Myxilla) in having a plumose rather than reticulate skeletal structure (Van Soest 2002: 610).
2. Pronax anchorata Bergquist & Fromont, 1988: 72 (type locality Hauraki Gulf, New Zealand). This New Zealand species was originally described in Pronax Gray, 1867: 536, preoccupied by Pronax Gray, 1867: 526, which is a Clionaidae, with species transferred to Phorbas Duchassaing & Michelotti, 1864 (Van Soest 2002: 585). Phorbas species have an ectosomal skeleton of tornotes, choanosomal skeleton of two sizes of plumosely arranged and echinating acanthostyles, and arcuate isochelae (Van Soest 2002: 614), whereas the New Zealand species P. anchorata Bergquist & Fromont, 1988 has an ectosomal skeleton of oxeas, a plumose choanosomal skeleton of two sizes of acanthostyles and tridentate anchorate chelae, making it a species of Myxilla (Styloptilon). The nomenclatural difference between M. (S.) ancorata (Cabioch, 1968) and M. (S.) anchorata (Bergquist & Fromont, 1988) is too slight, so the two are homonyms (ICZN Art. 58.10), and a new name is required for the latter species.
3. Summary. Myxilla (Styloptilon) ancoratum (Cabioch, 1968) is to be maintained as senior secondary homonym (ICZN 57.2). Myxilla (Styloptilon) anchorata (Bergquist & Fromont, 1988) is a junior secondary homonym without known synonym, and requires a new name (ICZN Art. 58.10 & 60.3), for which Myxilla (Styloptilon) fromontae nom. nov., named after Jane Fromont was proposed.
