Taxonomic remarks. The genus Siphonaria was originally described to contain four species, S. sipho, S. concinna, S. tristensis and S. exigua, without an original type species designation. Sowerby referred to two species as ‘typical species of the genus’ (“Adanson’s Mouret” (Le. Lepas mouret Adanson, 1757; unfigured) and “ Patella Sipho ”). However, none of these were available names. Gray (1847: 181) subsequently designated S. sipho as the type species. Anton (1838: 26) designated Siphonaria sowerbyi Michelin, 1832 and Hubendick (1946: 19) designated Siphonaria laciniosa (Linnè, 1758) as type species, but none of these taxa were originally included species rendering these subsequent type designations invalid (Art. 74.1 of the Code).
Several subsequent authors incorrectly attributed the genus name Siphonaria to Blainville, 1824, but Blainville (1824a: 268) explicitly attributed Siphonaria to Sowerby. Consequently, Blainville did not establish a junior homonym of Sowerby’s name. Hubendick (1946: 18) treated Iredale’s taxa Ellsiphon, Legosiphon, Hebesiphon, Mallorisiphon, Mestosiphon, Planesiphon (although not valid), Parellsiphon, Torquisiphon, Triellsiphon, and Pugillaria as junior synonyms of Siphonaria as these were essentially based on conchological attributes. Several authors treated Liriola as a subgenus of Siphonaria (e.g., Suter 1913: 601; Hubendick 1945: 60, 1946: 8–9, 18–19; Morrison 1963: 7; Abbott 1974: 335). By contrast, Fischer and Crosse (1900: 108) treated Liriola as a distinct genus. Contrary to Hubendick (1945: 15, fig. 1, 1946: 8, fig. 3), two determinant anatomical characters specified for the subgenus Liriola appear not to be diagnostic: The ‘epiphallus and spermoviduct’ (i.e. ED and CD) do not open separately (i.e., the genital pore is monaulic) in several species and a ‘spermatheca’ (i.e., BC) is present in the type species S. thersites as well as other species occasionally associated with this taxon (S. obliquata, S. tasmanica, S. funiculata, S. virgulata and S. obvirgulata, S. stowae, S. lateralis, S. acmaeoides, S. capensis, S. belcheri, and S. carbo). Indeed, all species studied herein possess a monoaulic genital opening and a BC as part of the RS. Hubendick (1946: 30) assigned Patellopsis Nobre, 1886 as a section to Liriola; however, incorrectly stated the type species to be S. pectinata (Linnè, 1758). However, the type species is S. algesirae Quoy & Gaimard, 1833 by original designation (Nobre, 1886: 32) although subsequently treated as a synonym of S. pectinata by Hubendick (1946: 43), Morrison (1972: 53), and Giribet & Kawauchi (2015: 5). The subsequent designation of S. lateralis Gould, 1848 as the type species for Kerguelenia Mabille & Rochebrune, 1889 by Hubendick (1945: 60) is invalid because S. lateralis was not originally included in Kerguelenia (Art. 67.2, 69.1 of the Code). Siphonaria redimiculum Reeve, 1856 and S. macgillivrayi Reeve, 1856 are the only originally included species. Powell (1946: 91) subsequently designated S. redimiculum Reeve, 1856 as the type species of Kerguelenia. However, Kerguelenia Mabille & Rochebrune, 1889 is preoccupied by Kerguelenia Stebbing, 1888 (Crustacea: Amphipoda). Finlay (1927: 442) noted the similarity of S. obliquata with Kerguenella, but for being conchologically “quite aberrant” placed it in a new genus, Benhamina. Torquisiphon has been treated as a junior synonym of Hebesiphon by Morrison (1972: 60). Hubendick (1946: 22) mentioned Talisiphon tasmanicus as a synonym of Siphonaria tasmanica implying that he likely considered Talisiphon as a junior synonym of Siphonaria. By contrast, Morrison (1963: 7) treated Talisiphon as a section of the subgenus Liriola. Hubendick (1946: 18) treated Mouretus as a synonym of Siphonaria. The type species of Mouretus is S. adansonii Blainville, 1824 by original designation of Blainville (1824b: 162), not ‘ M. mouretus Blainville’ (Morrison, 1972: 53; a nomen nudum). Hubendickula was ranked as section in Siphonaria s. str. by Hubendick (1955: 5–6). The name Planesiphon is unavailable from Iredale (1940: 437, 441) as no type species was designated (Art. 13.1 of the Code). However, Zilch (1959: 86), subsequently made the name available referring to Iredale’s (1940) description while designating Planesiphon elegans as the type species. He treated the taxon as a subgenus of Siphonaria. The prior type species designation of S. elegans Iredale, 1940 by McAlpine (1952: 42) is not valid because Planesiphon was not treated as an accepted name (Art. 69.1 of the Code).
Hubendick (1945, 1946, 1955) and Morrison (1963) treated Heterosiphonaria as a valid section of Siphonaria s. str. Benhamina has been ranked as a valid genus by Powell (1939: 217; 1946: 91; 1955: 120; 1979: 293, pl. 54, figs 12–13), Borland (1950: 385–393), Morton and Miller (1968: 302, 336, 338, 354, 378), and Morley (2004: 130), but as a section in Liriola by Hubendick (1945: 55; 1946: 9, 11, 18, 24–26, 64). Our results indicate that the monotypic genus Benhamina is unwarranted because its general morphological and molecular characteristics fall within the range of Siphonaria. Moreover, we synonymize Talisiphon Iredale, 1940 with Siphonaria, and its type species, S. virgulata, with S. funiculata. The type species of Simplisiphonaria Hubendick, 1945 is Siphonaria cookiana Suter, 1909 by original designation. This species is a junior objective synonym of Siphonaria australis Quoy & Gaimard, 1833 because of Boreham’s (1959) subsequent lectotype designation (a juvenile shell of S. australis from a mixed syntype lot; Jenkins, 1983: 1, 21, figs 3e–g). The type species of the following genus-group taxa are herein considered as junior synonyms of Siphonaria species: Mestosiphon Iredale, 1940 (type species M. eumelas = S. atra); Ellsiphon Iredale, 1940 (type species E. marza = S. denticulata); Triellsiphon Iredale, 1940 (type species Triellsiphon acervus = S. atra); Legosiphon Iredale, 1940 (type species L. optivus = S. viridis); Ductosiphonaria Hubendick, 1945 (type species ‘ S. bifurcata’ [non Reeve, 1856] = S. zelandica); Planesiphon Zilch, 1959 (type species P. elegans Reeve, 1856 = S. zelandica).
Siphonaria as delineated herein reveals considerable phylogenetic structure (Fig. 1). However, none of the principal clades retrieved herein is found to exhibit a consistent morphological feature that allows us to consistently distinguish its members from those of any other clade. Therefore, we treat all previously introduced genus-group names listed above as junior synonyms of Siphonaria. Given the lack of clearly identifiable diagnostic characteristics, we do not find it useful or even justifiable to maintain subgenera within Siphonaria for any of the species examined herein. The sole exception is Siphonaria thersites (type species of Liriola). This species is the sister group of all remaining Siphonaria species (Figs 1–4) and is distinguished by the combination of a very low-level occurrence intertidally, the animal not being fully enclosed by a reduced and often flattened shell, the BD in the RS totally enclosed within the CD and a relatively small and short SPM. Should these characters be revealed as synapomorphies of a distinct taxonomic lineage that incorporates additional extralimital species, then the name Liriola was available for such a natural group. However, none of the species from the IWP examined herein is member of this potential lineage.
