Removal of homonymy between Callyspongia truncata (Von Lendenfeld, 1887, p.768), Callyspongia truncata (Von Lendenfeld, 1887, p. 808), and Callyspongia truncata (Lindgren, 1897).
1. Chalinopora truncata Von Lendenfeld, 1887: 768 (type locality Port Jackson, Australia). The genus Chalinopora Von Lendenfeld, 1887: 740 was assigned to the synonymy of Callyspongia Duchassaing & Michelotti, 1864: 56 by Wiedenmayer (1989: 104), and Hooper & Wiedenmayer (1994: 103) proposed Callyspongia truncata as a valid species, which is maintained here, and is the senior secondary homonym of two other truncata species (ICZN Art. 57.3).
2. Siphonella truncata Von Lendenfeld, 1887: 808 (type locality Port Jackson, Australia). Although the genus Siphonella Von Lendenfeld. 1887: 742 was assigned to the synonymy of Siphonochalina Schmidt, 1868: 8 by Desqueyroux Faúndez & Valentine (2002a: 849) (opposed to assignment to Callyspongia by Burton (1934) and Hooper & Wiedenmayer (1994)), the species Siphonella truncata was reassigned to the synonymy of Callyspongia tuberculata (Von Lendenfeld, 1887) (originally as Siphonella, p. 723) by Hooper & Wiedenmayer (1994: 104). The species remains, however, a junior secondary homonym of Callyspongia truncata (Von Lendenfeld, 1887: 768), and required a new name (ICZN Art. 60.3).
3. Siphonochalina truncata Lindgren, 1897: 481 (type locality Southern Vietnam, Southeast Asia). This species was transferred to Callyspongia truncata (Lindgren, 1897) (cf. Lindgren 1898: 296) in various chemistry publications on South East Asian sponges, e.g. Nakao et al. (2002: 923) and this was confirmed by the World Porifera Database. This rendered it as a junior secondary homonym of Callyspongia truncata (Von Lendenfeld, 1887: 768), which required a new name (ICZN Art. 60.3).
4. Summary: Callyspongia truncata (Von Lendenfeld, 1887: 768) (originally as Chalinopora) is the senior secondary homonym based on page priority and is to be maintained (ICZN Art. 57.3). Callyspongia truncata (Von Lendenfeld, 1887: 808) is a junior secondary homonym based on page priority, and is also considered a junior synonym of Callyspongia tuberculata. However, homonymy is not removed, because this transfer violates ICZN Art. 59.1, which forbids transfer of a secondary homonym to the same genus. Therefore the name Callyspongia roberti nom. nov. was proposed to remove homonymy (ICZN Art. 60.3), named after Robert Von Lendenfeld. Callyspongia truncata (Lindgren, 1897) is another junior secondary homonym, which needed to be renamed to remove homonymy (ICZN Art. 60.3). Callyspongia lindgreni nom.nov. was proposed, named after Nils Gustaf Lindgren. [details]
