Taxonomy and systematics of the 'Maharaja Barbs' (Teleostei: Cyprinidae), with the description of a new genus and species from the Western Ghats, India.

Maharaja Barbs (Teleostei: Cyprinidae), endemic to the high-altitude streams of the northern Western Ghats are currently represented by a single species, Puntius sahyadriensis. Integrative taxonomic analysis of these fishes reveals them to form a distinct clade within the Cyprinidae, for which we propose the name Waikhomia gen. nov.

A new syntopic species of small barb from the Western Ghats of India (Teleostei: Cyprinidae).

A new species of the cyprinid genus Pethia is described from the Hiranyakeshi, a tributary of the Krishna River system in the Western Ghats mountain ranges of peninsular India. The new species, Pethia sahit, is syntopic-and shoals together-with Pethia longicauda, a species described recently from the same river. Pethia sahit is distinguished from P.

The identity of Aplocheilus andamanicus (Köhler, 1906) (Teleostei: Cyprinodontiformes), an endemic Killifish from the Andaman Islands, with notes on Odontopsis armata van Hasselt.

In his work on the fishes of the Andaman Islands, Francis Day (1870) collected large-sized specimens of Aplocheilus from the south Andamans. Despite differences in the size and dorsal-fin ray counts, Day refrained from recognising the Andaman Aplocheilus as a distinct species and considered it as Aplocheilus panchax, a species distributed in the Ganges delta and across the eastern coast of mainland India. However, Day mentioned the differences in fin-ray counts between these two populations.

Balitora chipkali, a new species of stone loach (Teleostei: Balitoridae) from the northern Western Ghats of India, with a note on the distribution of B. laticauda.

Balitora chipkali, a new species of stone loach, is described from the westward-flowing Astoli tributary of the Kali River system in the northern part of the Western Ghats, India. The species differs from its congeners in a combination of characters that includes: a single pair of maxillary barbels; a large eye, of diameter greater than 15% head length (HL); snout length less than 4 times eye diameter; gape of mouth less than 30% HL; upper lip with 9-12 papillae in first series and 3-8 papillae in second series; flattened body, of depth less than 15% standard length; caudal-peduncle length less than three times its depth, 66-68 lateral line scales, 11 caudal vertebrae excluding compound centrum, third infraorbital sensory canal tube straight; and a distinct color pattern with almost round 7 dorsal saddles not reaching lateral irregular crossbar markings. Balitora chipkali forms a monophyletic group with B.

Corrigendum: Redescription of Nemachilichthys rueppelli, a senior synonym of N. shimogensis (Teleostei: Nemacheilidae).

In Keskar et al. (2015) we emended the original name Cobitis rupelli Sykes, 1839, because Sykes (1839) specifically mentions that the species was named after Rüppell. The specific epithet 'rupelli', with a single 'p', is an incorrect original spelling and should be emended into 'ruppelli' as required by Article 32.

Redescription of Nemachilichthys rueppelli, a senior synonym of N. shimogensis (Teleostei: Nemacheilidae).

The hill-stream loach genus Nemachilichthys, an endemic of the Western Ghats of India, comprises two nominal species, N. rueppelli and N. shimogensis.

The identity of Hamilton's Ticto Barb, Pethia ticto (Teleostei: Cyprinidae).

While describing the fishes of Ganges, Hamilton described Cyprinus ticto (now allocated to Pethia) from south-eastern parts of Bengal. The unavailability of type material and insufficient diagnostic characters in the original description resulted in ambiguities in the identity of this species. In this paper, we clarify the identity of P.

Badis britzi, a new percomorph fish (Teleostei: Badidae) from the Western Ghats of India.

Badis britzi, the first species of the genus endemic to southern India, is described from the Nagodi tributary of the west-flowing Sharavati River in Karnataka. It is distinguished from congeners by a combination of characters including a slender body, 21-24 pored lateral-line scales and a striking colour pattern consisting of 11 bars and a mosaic of black and red pigmentation on the side of the body including the end of caudal peduncle, and the absence of cleithral, opercular, or caudal-peduncle blotches, or an ocellus on the caudal-fin base. Badis triocellus Khynriam & Sen is considered a junior synonym of B.

The identity of Pethia punctata, a senior synonym of P. muvattupuzhaensis (Teleostei: Cyprinidae).

Francis Day described Pethia punctata from Cochin, on the Malabar (south western) coast of India. Although, the species is now recovered from its synonymy with P. ticto, an accurate diagnosis and description have been lacking.

Horabagrus melanosoma: a junior synonym of Horabagrus brachysoma (Teleostei: Horabagridae).

Horabagrus melanosoma was described from West Venpala in the lower reaches of the Manimala River, in the state of Kerala, India. It was distinguished from its nearest congener, H. brachysoma based on a combination of characters including darker body colour, shorter pelvic fin and greater number of anal fin rays.

Pethia longicauda, a new species of barb (Teleostei: Cyprinidae) from the northern Western Ghats, India.

Pethia longicauda, a new cyprinid fish, is described from Hiranyakeshi River, Krishna drainage, Maharashtra, India. It can be distinguished from congeners based on a combination of characters including: a long caudal peduncle, incomplete lateral line, absence of barbels, upper lip thick and fleshy, distinct lateral fold on snout, 22-24 scales in lateral series, 5-6 lateral-line pored scales, nine predorsal scales, 9-10 prepelvic scales, 15-17 preanal scales, ½3/1/3½ transverse scales, 11-15 pairs of serrae on the distal half of the last unbranched dorsal-fin ray, 11-13 branched pectoral fin rays, 4+26 total vertebrae, 4+5 predorsal vertebrae, 4+13 abdominal and 13 caudal vertebrae, body iridescent silver in color with a black humeral spot, two black blotches on caudal peduncle and dorsal fin usually without any color bands or blotches but in breeding males with two rows of minute, indistinct black spots.
