Synonymy We cite here Van Soest et al.'s (2020: 63) explanation for the nomen novum.
Removal of homonymy between Mycale (Grapelia) vansoesti Hajdu, 1995 and Mycale (Mycale) vansoesti Calcinai, Cerrano, Totti, Romagnoli & Bavestrello, 2006.
1. Mycale (Grapelia) vansoesti Hajdu, 1995: 93 (type locality Mahé, Seychelles). The species was erected in the PhD thesis of Hajdu (1995: 93) as ‘Hajdu, submitted’, but the description fulfilled all the requirements for a valid new species, including indication of a holotype, type locality, adequate description of all features including illustrations and comparison with congeners. The thesis was printed in more than 50 copies and is distributed in several countries. Thus, the species name is available in the sense of the ICZN Art. 8. It is the senior primary homonym of M. vansoesti Calcinai et al., 2006 (ICZN Art. 57.2).
2. Mycale (Mycale) vansoesti Calcinai, Cerrano, Totti, Romagnoli & Bavestrello, 2006: 197 (type locality North Sulawesi, Indonesia). The species was earlier reported from Indonesia by Van Soest (1990: 305) as Mycale aff. cockburniana Hentschel, 1911: 289, which is a misapplication with an unrelated Australian species. Calcinai et al.’s extensive description as vansoesti created a junior primary homonym with Hajdu’s species. We discovered that Calcinai’s species has a subjective senior synonym, Biemna humilis Thiele, 1903: 944, which we have ascertained to be the same species by examination of slides of the type of B. humilis, ZMB 3203 (labeled as Desmacella humilis). The new name for the species is proposed as Mycale humilis (Thiele, 1903). The existence of a subjective senior synonym does not remove the homonymy (ICZN Art. 57.2), so a replacement name was needed.
3. Summary: Mycale (Grapelia) vansoesti Hajdu, 1995 is to be maintained as a senior primary homonym (ICZN Art. 57.2). Mycale (Mycale) vansoesti Calcinai et al., 2006 is a junior primary homonym, which is permanently unavailable.
To remove the homonymy Mycale calcinaiae nom. nov. was proposed, named after Barbara Calcinai. However, this was reassigned to the senior synonym Mycale humilis (Thiele, 1903).
4. Unfortunately, Van Soest et al. overlooked that Calcinai et al. (2017) already proposed M.(M.) corallina as replacement name for M. (M.) vansoesti sensu Calcinai et al. (2006), thus causing M. calcinaiae to become a junior synonym. Both new names are junior synonyms of Mycale humilis (Thiele, 1903). [details]
