... (1999: 84) also lists a fish identified as Barbus (Cyclocheilichthys) apogon by Shaw and Shebbare (1937: 34, fig. 30) in the synonymy of Oreichthys cosuatis. Shaw & Shebbare figured a poorly preserved specimen from North Bengal. Judging from the figure, it might be an Oreichthys as the figure shows the typical dark grey, crescent- shaped mark on each scale. It is further unlikely that the figure represents a Cyclocheilichthys as it has a smooth dorsal-fin spine, whereas in Cyclo- cheilichthys the dorsal-fin spine is strongly ser- rated. Cyclocheilichthys apogon is a species known only from SE Asia ( Kottelat et al, 1993;Kottelat, ...

... (1999: 85) also lists Puntius coorgensis Jayaram, 1991 as a synonym of Oreichthys cosuatis. Puntius coorgensis was described by Jayaram (1982) and is considered a valid species within the genus Puntius by Yazdani & Singh (1994). The figure of P. coorgensis in Jayaram (1982: 47) shows a fish that is clearly distinct from O. cosuatis due to the absence of black marks on dorsal and anal fin and the absence of a dark grey, crescent-shaped mark on each scale. Moreover, Jayaram (1982: 48) re- ports the absence of pores or tubercles on the snout. (Fig. 5); pharyngeal teeth in three rows: 1-4-2 (Fig. 3b). Size up to 25.8 mm ...

In the present communication, an attempt has been made to provide a systematic classification of freshwater fishes of West Bengal along with their local names, environment and conservation status, as far as possible. We recognized 267 species of freshwater fishes (186 primary freshwater species, 81 secondary freshwater species), belonging to 12 orders, 40 families and 123 genera. Thirteen species of exotic fishes have been introduced to freshwater bodies of the state. The top order with diverse species composition was Cypriniformes (117 species, 46 genera and 4 families). The most diverse family was Cyprinidae with 84 species and 35 genera. Freshwater fishes of West Bengal revealed existence of 109 ornamental fishes, 92 food fishes and 66 were ornamental or food fishes. Out of the 267 freshwater fishes, 17.97% are under threatened or near threatened categories. Updated checklist will lead to a better understanding of the freshwater fish diversity of West Bengal for development and conservation planning processes.

... For example, a few species retained in Puntius possess numerous rows of sensory papillae on the head, apparently an apomorphy shared by the closely-related species-group P. cauveriensis, P. dorsalis, P. kelumi and P. layardi , but not other species of Puntius. Among Asian cyprinine genera, this character-state occurs also in Cyclo cheilichthys, Eirmotus, Neobarynotus and Oreichthys (Kottelat, 1996;Tan & Kottelat, 2008;Schäfer, 2009). Likewise, some species of Dawkinsia develop nuptial tubercles on the snout and cheeks (Pethiyagoda & Kottelat, 2005a), a character that occurs also in many other cyprinid genera. ...
The tropical Asian cyprinid genus Puntius, which contains some 120 valid species, has long been suspected to be polyphyletic. Here, through an examination of external morphology, osteology, and analysis of 16S ribosomal RNA and cytochrome b gene fragments from 31 South Asian species hitherto referred to Puntius, we show that these fishes represent at least five lineages recognisable as genera. Puntius sensu stricto has the rostral barbels absent; last unbranched dorsal-fin ray weak or strong, smooth; and lateral line complete, with 22-28 pored scales. Systomus possesses maxillary and rostral barbels; last unbranched dorsal-fin ray stiff (‘osseous’), serrated; and lateral line complete, with 27-34 scales. Three new genera are proposed: Dawkinsia (type species Leuciscus filamentosus) is distinguished by lacking rostral barbels; having the last unbranched dorsal-fin ray smooth; lateral line complete, with 18-22 scales; and a juvenile colour pattern that includes three black bars on the body. Dravidia (type species Cirrhinus fasciatus) is distinguished by having both rostral and maxillary barbels present; lateral line complete, with 18–26 pored scales; dorsal fin with 4 unbranched and 8 branched rays, last unbranched dorsal-fin ray smooth; infraorbital 3 deep, partly overlapping the preoperculum; and free uroneural and postepiphysial fontanelle absent. Pethia (type species Barbus nigrofasciatus) is distinguished by having the last unbranched dorsal-fin ray stiff, serrated; infraorbital 3 deep, partially overlapping preoperculum; rostral barbels absent; maxillary barbels absent or minute; a black blotch on the caudal peduncle; and frequently, black blotches, spots or bars on the side of the body. The identities of Puntius sophore and Systomus immaculatus are clarified through the designation of neotypes; a lectotype is designated for Neolissochilus bovanicus; and precedence is given to the spelling bovanicus over bovianicus.

New species of freshwater fishes recorded for first time during last three decades form India is reviewed. In total 150 new species of freshwater fishes belonging to 5 order, 22 family and 44 genera have been emerged from different locality of India. Cypriniformes was the most dominant order represented by 69 species belonging to 5 family and 17 genera, followed by Siluriformes (58 species belonging to 8 family and 17 genera); Perciformes (19 species belonging to 6 family and 7 genera); Synbranchiformes (3 species belonging to 2 family and 2 genera) and Tetraodontiformes (1 species belonging to 1 family and 1 genera). Maximum number of species emerged from the Mizoram (32), followed by Manipur (29), Kerala (28), Arunachal Pradesh (17), West Bengal (14), and Karnataka (13). Of the 150 species, one species belong to the critically endangered category, 5 to the endangered, 9 to Vulnerable and 2 to Near Threatened.
Part I of the ichthyological type catalogue of the ZSM (Neumann 2006) reviewed the historic "Old Collection'', of which types were apparently lost in the Second World War. Part II refers to type material physically available in ZSM, including historic types saved and re-inventoried. Rebuilding the ichthyological collection after the war, Otto Schindler received with the so-called "Kahsbauer Donations" historic fish specimens from the Naturhistorisches Museum Wien (NMW). Among them are types from the Natterer and Thayer expeditions to Brazil, from the Haseman expeditions to South America and from Steindachner's late Brazil expedition in 1903. As far as possible, exchanged specimens were critically reviewed, traced to original lots and compared with NMW acquisition entries for unambiguous identification. Additional historic type material was recovered from the "Zoologische Praparatesammlung der Ludwig-Maximilians-Universitat Munchen" (ZPLMU), i.e. the illustrated syntype of Loricaria rest rata from the Spix Collection and syntypes from the Sagami Bay collected by Haberer and Doflein (i.e. Ditrema temmincki var. jordani and Leptocephalus lacrymatus). The use of the two museum abbreviations ''ZSM/LIPI" and "ZSM/CMK" for type material established during the curatorship of M. Kottelat at ZSM is clarified; material published with either abbreviation was neither intended for final deposition nor is available in ZSM. The whereabouts of material published as "ZSM" by Kottelat are discussed. Presently, the ZSM ichthyological collection contains 1735 type specimens: 53 holotypes, 28 syntypes, 4 neotypes, 2 lectotypes, 24 paralectotypes and 1624 paratypes of 166 nominal species representing 12 families. A total of 541 type specimens (36 holo-types and 505 syntypes) representing 51 families was lost during World War II. Since 1993,24 holotypes, 5 neotypes and 11 paratypes are missing from the collection. The fate of the ZSM types of Chromidotilatpia bosumtwensis Paulo, 1979 needs further research.
Fishes currently assigned to Oreichthys cosuatis from the Western Ghats are shown to belong to a closely-related group of three valid species: Puntius coorgensis, which is raised from synonymy, and two new species, O. duospilus and O. incognito. Oreichthys coorgensis can be distinguished from its congeners by a combination of characters that include 22-23+1-2 scales in the longitudinal series with 5-8 pored scales; 1/23/1/21/2 scales in the transverse row; 6-7 predorsal scales and usually a faint blackish spot on the caudal-fin base. Oreichthys duospilus, sp. nov., can be distinguished by possessing an almost complete lateral line with 11-21 pored scales and two black spots: one on the dorsal fin and the other on the anal fin. Oreichthys incognito, sp. nov., can be distinguished by a lateral line with 5 pored scales; 1/23/1/11/2 scales in the transverse row; 8 predorsal scales and a vertical black bar on the dorsal fin.
There are 3108 valid and named native fish species in the inland waters of
Southeast Asia between the Irrawaddy and Red River drainages, the small coastal drainages
between the Red River and Hainan, the whole Indochinese Peninsula, Andaman and Nicobar
Islands, Indonesia (excluding Papua Province, Waigeo, Aru [but Kai is included]), and the
Philippines. They belong to 137 families. Their taxonomy and nomenclature are reviewed. The
original descriptions of all 7047 recorded species-group names and 1980 genus-group names
have been checked in the original works for correct spelling, types, type locality and bibliographic references. The bibliography includes about 4700 titles. Synonymies are given, based on published information as well as unpublished observations.
The names of 49 introduced species and 347 extralimital taxa cited in the discussions have
also been checked. The original descriptions of all species not present in the covered area but
cited as type species of genera have been checked for availability, authorship, date and correct
spelling. The availability of some family-group names has been checked when there was suspicion of possible nomenclatural problems.
Bibliographic notes include new informations on the dates of publication of works by, among
others, Bleeker, Bloch, Heckel and Steindachner and discussion of authorship of names in various works.
