A new species of Osteobrama (Teleostei: Cyprinidae) from the Mahanadi River, India with a note on the validity of O. dayi
Abstract
A new species of the genus Osteobrama is described from the Mahanadi River, Tikarpada, Angul District, Odisha state, India. Osteobrama tikarpadaensis, new species, differs from its congeners in having two pairs of minute barbels; iii–iv unbranched dorsal-fin rays with 25–33 serrae on the last unbranched ray; 15–16 branched pectoral-fin rays, and 25–27 branched anal-fin rays. The status of Osteobrama dayi is discussed and shown to be a valid species. A key to the species of the genus is provided.
... cunma (Day, 1888), O. belangeri (Valenciennes, 1844), and O. feae Vinciguerra, 1890-are distributed in Southeast Asia, Myanmar, and China [17,19,20]. A recent addition to the genus is O. tikarpadaensis (Shangningam, Rath, Tudu and Kosygin, 2020), described from the Mahanadi River in Odisha, central India, and reported in the Erai River, Godavari drainages, Maharashtra [21,22]. Although O. alfredianus (Valenciennes, 1844) was originally documented in Mysore, peninsular India [18], subsequent taxonomic assessments have synonymized it with O. vigorsii [17]. ...
... In the realm of systematics, the presence or absence of barbels stands as a crucial taxonomic trait in Osteobrama [21,23]. When present, these barbels may manifest as a single pair of maxillary barbels or include both maxillary and rostral varieties, sometimes being minute or rudimentary in certain species. ...
... When present, these barbels may manifest as a single pair of maxillary barbels or include both maxillary and rostral varieties, sometimes being minute or rudimentary in certain species. Rostral barbels may either remain concealed in a groove or be visible only under microscopic examination, while in other species, they can be significantly longer, extending to the base of maxillary barbels [17,19,21]. The type locality of O. vigorsii is the Bhima River (a tributary of the Krishna River) at Pairgaon, Maharashtra, but there are also reports in the Krishna and Godavari Rivers [24,25]. ...
The taxonomy and geographical distributions of Osteobrama species have historically posed challenges to ichthyologists, leading to uncertainties regarding their native ranges. While traditional taxonomy has proven valuable in classification, the utility of an integrated approach is restricted for this particular group due to limitations in combining information from biogeography, morphology, and genetic data. This study addresses the taxonomic puzzle arising from the recent identification of Osteobrama tikarpadaensis in the Mahanadi and Godavari Rivers, casting doubt on the actual distribution and systematics of both O. tikarpadaensis and Osteobrama vigorsii. The research reveals distinctions among specimens resembling O. vigorsii from the Krishna and Godavari riverine systems. Notably, specimens identified as O. vigorsii from the Indian Museum exhibit two pairs of barbels, while those from the Godavari River in this study are identified as O. tikarpadaensis. Inter-species genetic divergence and maximum likelihood phylogeny provide clear delineation between O. vigorsii and O. tikarpadaensis. The study suggests that O. vigorsii may be limited to the Krishna River system in southern India, while O. tikarpadaensis could potentially extend from the Mahanadi River in central India to the Godavari River in southern India. Proposed revision to morphological features for both species, accompanied by revised taxonomic keys, aim to facilitate accurate differentiation among Osteobrama congeners. The data generated by this research provide a resource for future systematic investigations into cyprinids in India and surrounding regions. Further, the genetic diversity information obtained from various riverine systems for Osteobrama species will be instrumental in guiding aquaculture practices and formulating effective conservation action plans.

Osteobrama tikarpadensis Shangningam et al. (2020) is reported for the first time from Maharashtra, India. The species was originally described from the Mahanadi River, Tikarpada, Angul District, Odisha. It is distinguished from other members of the genus Osteobrama by having rostral and maxillary barbels; 25-26 branched anal-fin rays and 61-67 lateral line scales.
... The ichthyofauna of the Eastern Ghats region have not been thoroughly studied, compared to those of the Western Ghats (Rema Devi and Indra 2003). Recent descriptions of new fish species from the Eastern Ghats, however, suggest that this region is potentially important for ichthyofauna, and that the fish diversity could be underestimated (e.g., Shangningam et al. 2020;Jadhav et al. 2020;Prasad et al. 2020). ...
Pseudolaguvia permaris, a new sisorid catfish is described from the Mahanadi River basin in Odisha, India. The new species can be distinguished from congeners in having the following combination of characters: serrated anterior margin of dorsal-fin spine, thoracic adhesive apparatus not extending beyond base of last pectoral-fin ray, caudal peduncle depth 8.6–10.2% SL, body depth at anus 15.3–20.2% SL, adipose-fin base length 13.6–18.1% SL, dorsal to adipose distance 11.4–14.4% SL, length of pectoral-fin spine 19.3–28.0% SL, length of dorsal-fin spine 16.5–20.4% SL, head width 21.6–25.9% SL and indistinct, creamish bands on the body.

A new species of O s te o b ra m a wa s d i s c ove re d re c e n t ly by Shangningam et al. (2020) from river Mahanadi. This shows the rich diversity of this river. ...
Present findings provide a checklist of fishes of Mahanadi River, an important peninsular river of India. A total of 16 seasonal field explorations were conducted at 40 sites in entire stretch of Mahanadi from its origin in Chhattisgarh to its exit into Bay of Bengal during the period from November, 2012 - September, 2018. A total of 121 fish species from 21 orders, 43 families and 85 genera were recorded from Mahanadi. Cypriniformes represented by 49 species was found to be the most dominant order (40%) followed by Siluriformes with 23 species (19%). Cyprinidae was the richest family (33 species) followed by Danionidae (11 species) and Bagridae (7 species). Out of 121 fish species reported, 66 species were food fishes, 22 had ornamental importance while 33 species had both food and ornamental importance. The present checklist prepared from extensive sampling and exploratory surveys across the entire stretch of Mahanadi shall be helpful in monitoring and drawing up effective conservation strategies.
Osteobrama peninsularis has been reported in southern Indian drainages, particularly in the Krishna River drainage. This study provides new findings of O. peninsularis in two distant locations: the Kangsabati River (Suvarnarekha River drainage) in West Bengal and Wyra Lake (Godavari River drainage) in Telangana. This marks the first record of O. peninsularis in eastern India, specifically in West Bengal. The species can be distinguished from other Osteobrama members by its 28–31 branched anal-fin rays and 55–60 lateral line scales, along with other unique morphological features. Mitochondrial cytochrome oxidase C subunit I gene sequences from specimens collected in Suvarnarekha and Godavari River drainages cluster together in the phylogenetic analysis, indicating that the clade of O. peninsularis is distinct and maintains significant genetic distance from its congeners.
Osteobrama cotio is considered to be a widespread species in India and Bangladesh. Mitochondrial DNA (COI, 16S rRNA) shows that populations from the Meghna River, Karnafuli and Sangu Rivers, Narmada River, and Godavari River are genetically distinct from each other. No morphological differences were found to separate Meghna and Karnafuli+Sangu populations, however. A putative new species, “Osteobrama serrata” has been described from the Barak River basin, stated to be distinguished from O. cotio by the presence of a serrated third dorsal-fin ray. The description of “O. serrata” does not fulfil requirements of the International Code of Zoological Nomenclature, (International Commission on Zoological Nomenclature 1999) and the name is thus unavailable. Published DNA sequences of “Osteobrama serrata” are identical to sequences of O. cotio from Bangladesh. As mentioned already in the original description, O. cotio has a serrated third dorsal-fin ray.
Osteobrama bhimensis (Singh & Yazdani) was described from the Ujani wetland on Bhima River in Maharashtra, India, about 100 km downstream of the type locality of O. vigorsii (Sykes). Based on examination of the type material of O. bhimensis and comparison with O. vigorsii collected from different localities in the Krishna and Godavari River systems, we show that O. bhimensis is conspecific with O. vigorsii.
Osteobrama cunma, originally described from Moulmein, Myanmar, has so far been considered a subspecies of Osteobrama cotio. Based on examination of specimens from Brahmaputra and Chindwin basins, O. cunma has now been given species status. The species differs from its nearest congener, O. cotio, in having less numbers of branched anal fin rays (26 vs. 31); lateral line scales (48 vs. 66); predorsal scales (20 vs. 27); scale rows between dorsal fin base and lateral line (9 vs. 14); scale rows between pelvic fin base and lateral line (8 vs.12) and circumpeduncular scales (20 vs. 28). Osteobrama feae Vinciguerra, originally known from upper Myanmar has been collected from the Maklang river of Manipur, and is reported as a new record for India. Brief descriptions of O. belengeri, O. cotio, O. cunma and O. feae are given in this paper.
