“…However, since the name "calamara", is preoccupied by Cuvier, 1829, Day's "calamara" has no taxonomic significance in the context of A. berda. Castelnau (1861) described Pagrus caffer (type probably lost, P. Pruvost, pers. comm.)…”

A new sparid species, Acanthopagrus taiwanensis, is described on the basis of six specimens that were previously misidentified as A. berda (Forsskål, 1775), collected from Tung-kang, southwestern Taiwan. Acanthopagrus taiwanensis and A. berda are similar in overall appearance, both with deep bodies. However, A. taiwanensis differs from the latter in having a more rounded body, broadly rounded anteriormost head squamation with around 10 somewhat smaller scales anteriorly, 3 or 4 cheek scale rows, thin upper and lower lips, older individuals with a ridge on dorsal profile in front of eye and upper profile of head evenly convex, head and body black with sharply contrasting white area ventrally, a dark spot at upper base of pectoral fins, and flat molar teeth. In contrast, A. berda has a deeper body, broadly rounded anteriormost head squamation with around 20 small scales anteriorly, 5 or 6 cheek scale rows, thick upper and lower lips, larger individuals with a weak ridge in profile in front of eye and concave snout profile, head and body silvery gray, no black spot at upper base of pectoral fins and somewhat pointed molar teeth. Older individuals of A. berda also develop a strong concavity of the ventral edge of the first two infraorbitals above the posterior part of upper jaw, while the edge is relatively straight or weakly concave in A. taiwanensis. We discuss the nominal species that have been placed in synonymy with A. berda and contrast A. taiwanensis with similar congeners.

The taxonomy of the Western Indian Ocean species of Acanthopagrus is reviewed. A new species, A. omanensis, is illustrated and described from two specimens. Acanthopagrus vagus (Peters, 1852) is resurrected from the synonymy of Acanthopagrus berda (Forsskå l, 1775), redescribed, and compared with A. berda. Acanthopagrus vagus differs from all congeners in the following combination: scale rows between fifth dorsal-fin spine base and lateral line 3K; front edge of dorsal scaly area on head with a median W-shaped scaleless area anteriorly; second anal-fin spine longer than third anal-fin spine; ventral edge of first two infraorbitals straight (slightly curved in fish more than 25 cm SL); preopercle flange with 0-6 scales, number increasing with growth, scales obvious on fish more than 20 cm SL; anal fin with pale rays, and a black streak near the base on each inter-radial membrane; molariform teeth well developed on both jaws. Acanthopagrus berda is differentiated from all congeners by the following combination: scale rows between fifth dorsalfin spine base and lateral line 3K; anterior head profile slightly convex, front edge of dorsal scaly area of head convex, with small scales anteriorly; ventral edge of first two infraorbitals with a strongly curved concavity that receives the enlarged tip of the maxilla in fish larger than 13 cm SL; no scales on preopercle flange; second anal-fin spine clearly longer than third anal-fin spine; anal fin almost completely black (no pale rays); molariform teeth well developed, lower jaw teeth rows strongly curved laterally at rear of jaw. Acanthopagrus omanensis, new species, is discernible from all congeners by the following combination: scale rows between fifth dorsal-fin spine base and lateral line 5K; front edge of dorsal scaly area on head forming an obtuse angle anteriorly; ventral edge of first two infraorbitals straight; no scales on preopercle flange; second anal-fin spine slender and subequal to third anal-fin spine; dorsal and caudal fins with wide black margins; upper and lower molariform teeth poorly developed. Junior synonyms of A. berda and A. vagus are discussed, with notes on other congeners, including nominal species of Sparidentex, which are sometimes confused with species of Acanthopagrus. A key to species of Acanthopagrus from the Western Indian Ocean is presented.

“…Four additional genetic lineages are still awaiting taxonomic delineation , Waters & Wallis 2000,b, Waters et al 2001a,b, McDowall 2006b, Burridge et al 2007, Crow et al 2009. A similar case is also being observed in South Africa for the nonmigratory Cape Galaxias, Galaxias zebratus (Castelnau, 1861), where ten deeply divergent genetic lineages flag an unresolved species complex (Waters & Cambray 1997, Wishart 2002, Wishart et al 2006, Chackona et al 2011.…”

The systematics of the Galaxias olidus hyper-species complex from freshwater habitats in south-eastern, mainland Australia is revised. Galaxias olidus Günther 1866 is redescribed, Galaxias fuscus Mack 1936 and Galaxias ornatus Castelnau 1873, previously synonymised with G. olidus (sensu lato), are reinstated as valid taxa and redescribed, and 12 taxa are described as new: Galaxias aequipinnis sp. nov., Galaxias arcanus sp. nov., Galaxias brevissimus sp. nov., Galaxias gunaikurnai sp. nov., Galaxias lanceolatus sp. nov., Galaxias longifundus sp. nov., Galaxias mcdowalli sp. nov., Galaxias mungadhan sp. nov., Galaxias oliros sp. nov., Galaxias supremus sp. nov., Galaxias tantangara sp. nov., and Galaxias terenasus sp. nov. These species are morphologically similar and, whilst there is extensive overlap in meristic counts and morphometric characters, each can be diagnosed by unique combinations of characters, including allozyme loci and colour pattern; morphological diagnosis is improved greatly if based on freshly formalin-fixed material. Galaxias schomburgkii Peters 1868, Galaxias bongbong Macleay 1881, Galaxias kayi Ramsay & Ogilby 1886 and Galaxias oconnori Ogilby 1912 are retained as junior synonyms of G. olidus (sensu stricto). The types for Galaxias findlayi Macleay 1882 are lost and no specimens matching its description were collected or examined from the Mt. Kosciuszko region; it is also currently retained as a junior synonym of Galaxias olidus s.s. The species G. terenasus sp. nov. and G. arcanus sp. nov. are the most morphologically specialised in the complex and G. olidus s.s remains the most morphologically variable species. It also remains the most widespread taxon, though its previously known distribution is reduced, particularly in the south-west of its range. Nine species are narrow-range endemics, known from one, or only a few, locations, and these restricted distributions most probably reflect the fragmentation and reduction of former ranges caused by the effects of alien salmonids. Eleven species are of conservation concern, most are considered critically endangered.
