Psammoperca datnioides Richardson 1848, long considered a synonym of P. waigiensis (Cuvier in Cuvier & Valenciennes 1828), is redescribed as valid species 1848. The likely to be endemic Australia, where it was formerly waigiensis, but differs from having the following characters: more slender body (mean depth 28.9% SL vs. mean 36.7% waigiensis), pored lateral-line scales 49–54 (vs. 46–48 scale rows above and below lateral line 6½ / 10½–11½ (vs 4½ 9½–10½ vertical at hind margin maxilla...

Platyinius amoenus Snyder 1911 has long been considered a junior synonym of Pristipomoides argyrogrammicus (Valenciennes 1832), however, the two are discernible as distinct species from color patterns and counts gill rakers based on examination their type materials non-type specimens. Furthermore, genetic differences molecular analysis among (mtDNA, COI gene) strongly support validity both species. can be readily distinguished P. in having no white margin to dorsal, anal, caudal fins,...

The taxonomic status of the Bay Bengal nominal sparid species Coius datnia Hamilton, 1822 and Acanthopagrus longispinnis (Valenciennes, 1830) are reviewed investigated both morphologically genetically. Because inadequate description no type specimen, has recently been considered to belong Sparidentex, a genus without molarifom teeth. Critical examination original specimens from locality adjacent areas reveal that belongs Acanthopagrus, with an inner series molars. Furthermore, previously...

Sparid fishes consist of approximately 115 species in 33 genera that are broadly distributed tropical and temperate coastal waters. Although several phylogenetic analyses were conducted based on specific molecular markers, their classification remains unresolved. Here, we present the most comprehensive phylogeny family Sparidae to date, cytochrome b (cyt-b) genes. We determined 18 sequences sparids among 72 individuals representing 66 with 23 outgroup species. Phylogenetic trees constructed...

Museum fish specimens are invaluable resources for genetic studies, but extraction of high quality DNA is often problematic. In this study, hairtail fishes the genera Trichiurus and Lepturacanthus (family: Trichiuridae) representing a wide range preservation histories three different methods were analyzed mitochondrial (mtDNA) extraction, amplification sequencing marker genes. A total six protocols, including commercially available kit, compared in study. Amplification conserved genes such...

The taxonomy of the Western Indian Ocean species Acanthopagrus is reviewed. A new species, A. omanensis, illustrated and described from two specimens. vagus (Peters, 1852) resurrected synonymy berda (Forsskål, 1775), redescribed, compared with berda. differs all congeners in following combination: scale rows between fifth dorsal-fin spine base lateral line 3; front edge dorsal scaly area on head a median W-shaped scaleless anteriorly; second anal-fin longer than third spine; ventral first...

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. taiwanensis and are similar in overall appearance, both with deep bodies. However, differs latter having a more rounded body, broadly anteriormost head squamation around 10 somewhat smaller scales anteriorly, 3 or 4 cheek scale rows, thin upper lower lips, older individuals ridge dorsal...
