The taxonomy and nomenclature of the fishes of the superfamily Cobitoidea (suborder Cobitoidei minus Catostomidae) are reviewed. Original descriptions of all 1499 recorded species-group names and 185 genus-group names have been checked for correct spelling, types and bibliographic references. The bibliography includes about 1010 titles. 1043 valid species in 111 valid genera are recognised. Synonymies are given, based on published information as well as unpublished observations. Endings consistent with the three possible Latin grammatical genders of genus-group names are indicated for all species-group names; basic tools are provided to establish the correct endings in most simple cases. The main nomenclatural acts are: - new family-group names: Serpenticobitidae, Barbuccidae; - new genera: Ambastaia (type species: Botia nigrolineata), Theriodes (type species: Acanthophthalmus sandakanensis), Speonectes (type species: Sundoreonectes tiomanensis); - lectotype designation: Cobitis stephanidisi (sensu Economidis, 1992); - declaration as nomen protectum: Cobitis biwae; - declaration as nomen oblitum: Cobitis schlegeli; - first reviser action on precedence of simultaneous synonyms: Parabotia kimluani over P. vancuongi, Cobitis taenia turcica over Cobitinula anatoliae, Sewellia medius over S. grandis, Parasewellia monolobata over P. polylobata, Cobitis turio over C. bilturio, Triplophysa bashanensis over T. longchiensis, Yunnanilus macrositanus over Y. forkicaudalis; - first reviser action on correct spelling of: Parabotia vancuongi, Cobitis fahireae, Hemimyzon songamensis, Sewellia analis, Parasewellia polylobata, Vanmanenia monofasciodorsalata, V. trifaseudorsala, Oreonectes microphthalmus, Paracobitis posterodorsalus, Yunnanilus macrositanus, Y. forkicaudalis, Y. spanisbripes. © National University of Singapore and the author.

Cyclocheilichthys is the valid name for the genus that includes Barbus apogon Valenciennes. Cyclocheilichthys has precedence over Anematichthys, which is a simultaneous objective synonym. If C. enoplos is considered not to be congeneric with C. apogon, the valid name for a genus that includes it is Cyclocheilos. Copyright © 2013 Magnolia Press.

Two new species of Squalius are described from the Seyhan River drainage in Turkey: S. adanaensis from the lower part of the drainage and S. seyhanensis from the upper part. Squalius adanaensis is distinguished from the other species of the genus in Anatolia, among other characters, by having the flank scales with a dark spot on each scale pocket but covered by the posterior margin of the previous scale, and very few melanophores along the posterior margin; 38-42 + 1-2 lateral line scales; and a maximum known size of 157 mm SL. Squalius seyhanensis is distinguished from other species of the genus in Anatolia, among other characters, by having the flank scales with a dark spot on each scale pocket, exposed, and densely-set melanophores along the posterior margin, forming a conspicuous reticulate pattern; 42-44 + 1-2 lateral line scales; and a maximum know size of 240 mm SL.

Salmo okumusi, new species, is described from western tributaries of the Euphrates River. It is distinguished by a greyish body, with the flank and back covered by numerous irregularly shaped small black spots and dots, imparting a peppered or slightly marmorated appearance; few to numerous red spots on body, organized in two to six irregular longitudinal rows on middle part of flank, each red spot usually comprising three or four smaller red dots wholly or partially coalescent; adipose fin grey, conspicuously coloured, with three or four red to orange spots on its free edge; 103-112 lateral line scales; 26-28 scales rows between lateral line and dorsal-fin origin; 18-21 scale rows between anal-fin origin and lateral line; length of maxilla 8.7-9.6 % SL in males, 8.1-9.1 in females. Salmo euphrataeus, new species, is described from northeastern tributaries of the Euphrates River. It is distinguished by a brownish body in life; few (4-54) black spots on body, restricted to back (usually missing in predorsal area) and upper part of flank, mostly anteriorly; few (13-53) red spots on body, usually organized in two to five irregular longitudinal rows on median and lower part of flanks; adipose fin almost reaching base of caudal fin in males larger than 210 mm SL, without or with up to three red or orange spots on free edge; 112-120 lateral line scales; 28-31 scale rows between lateral line and dorsal-fin origin; 20-24 scale rows between anal-fin origin and lateral line; length of maxilla 9.6-11.4 % SL in males, 8.4-10.2 in females.

Four species of Salmo are known from the Mediterranean drainages of southern Anatolia. Salmo platycephalus, from the Seyhan drainage, is redescribed. It is distinguished by the markedly flattened upper profile of the head, a marbled colour pattern in specimens larger than about 170 mm SL and 23-25 gill rakers on outer side of first gill arch. Salmo chilo, new species, is described from Akdere Stream (a tributary of Ceyhan River). It is distinguished by a strongly convex dorsal profile of head, a blunt snout, a conspicuously subterminal mouth, with fleshly maxilla and lower lip. Salmo labecula, new species, is described from from Ecemis. (in lower Seyhan drainage), Kartoz and Zindan streams (Köprüçay drainage). It is distinguished by the absence of red spots on the body in specimens larger than approximately 70 mm SL, and the presence of numerous black spots on middle of flank, and half of upper and lower flank. Salmo opimus, new species, is described from Tekir, Firniz, Göcüksu (Ceyhan drainage) and Alara streams (a costal drainage). It is distinguished by a markedly convex predorsal area in specimens larger than 170 mm SL (reflected by a deeper body in males), a greyish body, with black spots distinct only on anterior part, usually located on upper part of flank, sometimes on back; and with few red spots (13-47), usually organized in three to five irregular longitudinal rows on middle part of flank. © 2012 by Verlag Dr. Friedrich Pfeil, München, Germany.

Pleuronectes bilineatus Bloch, 1787 (now Paraplagusia bilineata), "Cynoglossus bilineatus (La Cepède, 1802)", and Paraplagusia blochii Bleeker, 1851, are objective synonyms as they are based on the same type material. "Achirus bilineatus La Cepède, 1802" was not proposed as a new species but was a new combination of Pleuronectes bilineatus. Paraplagusia blochii was not a new species but a new replacement name for Pleuronectes bilineatus. "Cynoglossus bilineatus (La Cepède, 1802)" should be called C. quadrilineatus (Bleeker, 1851). Paraplagusia bleekeri, new species, is proposed for the species erroneously called Paraplagusia blochii by earlier authors. © National University of Singapore.

The Asian bagrid catfish genus Hemibagrus is revised. Eight species groups (H. baramensis, H. guttatus, H. menoda, H. nemurus, H. olyroides, H. planiceps, H. pluriradiatus, and H. wyckii species groups) are recognised, some of which may be natural. They can be diagnosed chiefly by a combination of characters: vertebral number, length of the adipose-fin base, and colouration. The identification of Hemibagrus species is difficult mainly because of the lack of well-defined characters and considerable plasticity in measurements commonly used for diagnosing species in other catfish groups. In this study, other taxonomic characters have been investigated to determine their usefulness in differentiating the species. It was found that morphological characters associated with the adipose fin (length of adipose-fin base, dorsal to adipose distance, and shape of adipose fin), head (shape of snout and head width relative to its length), and eye (eye diameter and interorbital distance) are characters useful in species differentiation. Thirty-two valid species are recognised in this study, of which three are described as new, viz. H. divaricatus from western Peninsular Malaysia, H. lacustrinus from Danau Singkarak and its associated drainages in western Sumatra, and H. semotus from northeastern Borneo. © National University of Singapore.
