A new glyptosternine catfish, Creteuchiloglanis arunachalensis is described on the basis of a single specimen collected from the upper Brahmaputra River drainage, northeastern India. The new species is distinguished from its congeners by the following characters: shorter adipose-fin base (25.9 vs. 26.2-37.3 % standard length; SL) except C. longipectoralis; shorter maxillary barbel (71.2 vs. 75.2-99.8 % head length) except C. macropterus; and longer prepelvic (45.4 vs. 36.4-44.9 % SL) except C. brachypterus. It can be further differentiated by a combination of the following characters: pectoral fin not reaching pelvic-fin origin; pelvic fin not reaching at vertical through adipose-fin origin; pale patches on body except occipital region; absence of milky-white patch on the base of posterior end of maxillary barbel; longer post adipose distance (10.1 % SL); tip of rectal lobe obtusely rounded; caudal-fin lobes equal; posterior margin of caudal fin slightly convex; adipose-fin separate from caudal fin; and caudal fin with broad bean-shaped medial band.

Glyptothorax dikrongensis, a new species of sisorid catfish from the Dikrong River in northeastern India, is described. Glyptothorax dikrongensis can be differentiated from all congeners, except G. indicus, G. rugimentum and G. obliquimaculatus, by the presence of an unculiferous patch on the posterior region of the lower lip, in between the inner mandibular-barbel bases, and unculiferous striae of the thoracic adhesive apparatus extending anteriorly onto the gular region. Glyptothorax dikrongensis is distinguished from G. indicus by the following combination of characters: equal distance between the posterior end of the pectoral-fin base and the pelvic-fin origin and between the pelvic-fin and the anal-fin origin (vs. distance between posterior end of pectoral-fin base and pelvic-fin origin greater than between pelvic-fin origin and anal-fin origin), and the pelvic-fin origin anterior to or almost at a vertical through the posterior end of the dorsal-fin base (vs. posterior to the dorsal-fin base). Glyptothorax dikrongensis is distinguished from G. rugimentum in lacking vertical bars on the body and caudal peduncle, and having a deeper caudal peduncle (8.4–9.2 vs. 6.1–7.6% SL) and a shorter dorsal-fin spine (10.1–11.1 vs. 15.2–18.6% SL). It is distinguished from G. obliquimaculatus in lacking dark, oblique blotches on the body, and in having a shorter dorsal-fin spine (10.1–11.1 vs. 13.4–16.4% SL).
Catfish are a diverse group of fish representing more than 3,000 species under 478 genera and 36 families. They constitute 1/3 of the freshwater fish fauna of the globe. Diversity of catfish in India is the highest in Northeastern Hills, Gangetic River System and the Western Ghats. Mizoram, situated in the north eastern part of India, covers an area of 21,081km2 and all the rivers are draining into three major drainage namely Barak (Ganga-Brahmaputra Basin), Karnaphuli and Kolodyne basin. Kolodyne River (Chhimtuipui in Mizoram) is a drainage that flows between the Ganga-Brahmaputra drainage and Chindwin-Irrawaddy drainage which originates from the western face of the Chin Hills in Myanmar and flows into the Bay of Bengal near Sittwe in Myanmar. Ichthyological field survey was conducted during May 2010 to August 2011 from 5 randomly selected stations in 5 rivers flowing to Kolodyne drainage and their tributaries of Mizoram. A total of 10 species of catfish including two undetermined Pterocryptis sp. and Amblyceps sp. under 6 families and 8 genera were recorded during the study. Out of the 6 families, occurrence is dominated by Sisoridae (40%) followed by Bagridae (20%) and Siluridae, Schilbeidae, Amblycipitidae, Erethistidae (10% each). The study also revealed the new occurrence report of 3 genus of catfish viz. Pterocryptis, Amblyceps and Bagarius from Kolodyne drainage of Mizoram. Previous ichthyological studies from this drainage were also reviewed and 16 species of catfish under 6 families and 9 genera can be ascertained from Kolodyne drainage of the state. We identified liming and dynamite fishing to be the most destructive threats to not only catfishes but also all the freshwater fishes of this area. Overfishing and introduction of invasive exotic food fishes into dam reservoirs and lowland river areas were the other most critical threats.

RESUMEN: Los peces bagre del género Glyptothorax se distribuyen ampliamente, con nada menos que 40 especies nominales reportadas en India, donde normalmente habitan en arroyos de montaña con corrientes rápidas y tramos que fluyen más rápido en ríos y arroyos mas grandes. Registramos una nueva distribución biogeográfica de tres especies de Glyptothorax de las afluentes de las llanuras del norte de la cuenca del Ganges. Los especímenes se recolectaron durante la pesca experimental para estudios de biodiversidad con atarraya (2010-2012). Mientras que G. conirostris se capturó en el canal del río Ganges, G. cavia y G. telchitta fueron capturados en el río Gomti. Descripciones anteriores son basadas en especímenes preservados, presentamos características diagnósticas y redescripción ilustrada basada en especímenes frescos.PALABRAS CLAVE: nueva distribución, Glyptothorax conirostris, G. telchitta, G. cavia, cuenca Ganges, India
This paper communicates the extension of the distribution range of Batasio merianiensis in Sille River in the upper Brahmaputra drainage, East Siang District, Arunachal Pradesh. Detailed examinations of the specimens revealed existence of few morphological variations against those reported by Heok Hee Ng in 2009 on the following characteristics: by having a longer preanal (70.4-73.4 vs. 66.3-68.2% SL); a longer prepectoral (25.1-29.3 vs. 21.4-25.7% SL); a longer adipose-fin base (22.0-27.6 vs. 16.9-22.2% SL); a shorter post-adipose distance (11.6-13.4 vs.13.4-15.5% SL); a deeper body at anus (depth 18.3-20.8 vs.15.2-18.4% SL) and broader head (width 17.6-20.0 vs.13.5-16.2 % HL). Few additional characters of the fish are included along with brief information on its habitat. The LIPUM, the semitraditional method of fishing in the river is identified as a major threat to this species.
Two new species of Pseudecheneis, rheophilic catfishes (Teleostei: Sisoridae) from Nepal
2005
Two new species of sisorid catfish of the genus Pseudecheneis are described from tributaries of the Ganges River in Nepal: Pseudecheneis crassicauda and P. serracula. Pseudecheneis crassicauda can be distinguished from congeners by a unique combination of 38-39 vertebrae, caudal peduncle depth 6.0-6.6% SL, eye diameter 7.5-8.3% HL, length of adipose-fin base 20.3-24.3% SL, pelvic fins reaching the base of the first anal-fin ray, and the presence of pale spots on the body. Pseudecheneis serracula can be distinguished from congeners in having a unique combination of 36-38 vertebrae, strongly elevated neural spines of the last 2-3 preanal and first 6-7 postanal vertebrae, length of adipose-fin base 26.8-30.4% SL, pelvic fins reaching the base of the first analfin ray, and the presence of pale spots on the body.

The current study encompasses various key dimensions, including the analysis of bio-ecological parameters within freshwater streams, as well as the assessment of diversity, seasonality, and distributional patterns of endemic stream-fish species in the Manjalaru streams of the Palani hills. Nevertheless, the implementation of effective conservation measures to address the adverse impacts on these ecosystems has been notably sluggish and insufficient. Consequently, numerous aquatic fish species are experiencing a rapid decline. The primary factors contributing to the decline in biodiversity within freshwater streams are linked to habitat degradation and reduced water depth, the introduction of non-native species, water diversion activities, pollution, and the consequences of seasonal variations. The genus Cyprinidae, presently comprising a collection of species, encompasses a diversity of organisms within its taxonomic structure. Specifically, this genus comprises a minimum of eleven distinct species, all of which are native to the freshwater ecosystem of the Manjalaru stream situated in the Palani Hills of the Western Ghats. While these species are commonly encountered in the southern region of India and have historically served as a source of sustenance, there has been limited understanding regarding the extent of morphological variations existing both between and within these species. Additionally, the interrelationships between species, as well as the intraspecific genetic diversity, remained largely unexplored until now. This study has contributed valuable insights into the conservation and distributional patterns observed within the Punitius species, highlighting a noteworthy level of diversity among the species under investigation. The findings underscore the necessity for more comprehensive bio-geographic sampling and a thorough analysis of morphological data to unveil the inherent natural lineage within this genus. The outcome of this research hold potential significance for future endeavors, facilitating an enhanced
