    First record of hagfish (Cyclostomata: Myxinidae) in Indian waters2017In: Journal of Threatened Taxa, ISSN 0974-7893, E-ISSN 0974-7907, Vol. 9, no 6, p. 10365-10368Article in journal (Refereed)
    Abstract [en]

    One specimen of hag fish Eptatretus sp. was collected from the Arabian Sea, off Kerala coast of India at 500-600 m depth. The phylogenetic analysis using the sequence of mitochondrial gene cytochrome oxidase C (CO1) suggested the Eptatretus sp. collected from India is distinct from all other species where sequence data is available and P ID (Liberal) for Eptatretus sp. collected from India is 0.96, indicating a high probability that an unknown member of the putative species would be correctly identified as a member once more specimens are collected.

    Hagfish phylogeny and taxonomy, with description of the new genus Rubicundus (Craniata, Myxinidae)2013In: Journal of Zoological Systematics and Evolutionary Research, ISSN 0947-5745, E-ISSN 1439-0469, Vol. 51, no 4, p. 296-307Article in journal (Refereed)
    Abstract [en]

    A recent phylogenetic analysis of the Myxinidae based on the 16S rRNA gene resulted in synonymization of Paramyxine with Eptatretus. This created homonymy of Paramyxine fernholmi with Eptatretus fernholmi and Paramyxine wisneri with Eptatretus wisneri. In order to resolve this nomenclatural dilemma, we made a more extensive phylogenetic assessment of the Myxinidae and examined the nomenclature of the family. We used 75 sequences (37 of which new for this study) of a 561 bp fragment of the 16S rRNA gene, representing 33 species, and 72 sequences (37 of which new for this study) of a 687 bp fragment of the cytochrome c oxidase subunit I (COI) gene, representing 23 species, to reconstruct the phylogeny of Myxinidae. The monophyly of the subfamily Myxininae, traditionally characterized by having a single pair of external gill openings, was rejected (0.50 Bayesian posterior probability) by the 16S analysis, but supported by the COI and combined COI+16S analyses (0.99 and 0.81 Bpp, respectively). The monophyly of the subfamily Eptatretinae, characterized by having several pairs of external gill openings, was not supported by the 16S analysis and rejected by the COI and combined COI+16S analysis due to the placement of Eptatretus lopheliae as the earliest branch of Myxinidae (0.71 and 0.57 Bpp, respectively). Eptatretus lopheliae and Eptatretus rubicundus formed a monophyletic group and were allocated to a new genus, Rubicundus, characterized by the presence of an elongated tubular nostril and reddish coloration. A new monotypic subfamily, Rubicundinae, was proposed for Rubicundus. The synonymy of the genera Paramyxine and Quadratus with Eptatretus was confirmed. E. fernholmi is renamed Eptatretus luzonicus. Eptatretus wisneri was renamed Eptatretus bobwisneri. Petromyzon cirrhatus Forster, 1801, Homea banksii Fleming, 1822, and Bdellostoma forsteri Müller, 1836 are synonyms, but no type specimens are known to exist. Petromyzon cirrhatus was designated as type species of Eptatretus, conserving present usage. Gastrobranchus dombeyi Shaw, 1804 has priority over other names for Chilean myxinids. Bdellostoma stoutii was designated as type species of Polistotrema Gill. The validity of the Western Atlantic Myxine limosa as distinct from the Eastern Atlantic Myxine glutinosa was confirmed.

    Chalinochromis cyanophleps, a new species of cichlid fish (Teleostei: Cichlidae) from Lake Tanganyika2014In: Zootaxa, ISSN 1175-5326, E-ISSN 1175-5334, Vol. 3790, no 3, p. 425-438Article in journal (Refereed)
    Abstract [en]

    Chalinochromis cyanophleps is described from nine specimens, the largest 129 mm SL, from Namansi. It differs fromother species of Chalinochromis in plain trunk colouration, absence of black stripes on the head, relatively narrow lips, presence of tricuspid jaw teeth, and presence of five rather than four dentary lateralis foramina. The blue iridescent stripe below the eye is shared with other lamprologin cichlids, but is broader and more conspicuous in C. cyanophleps.

    Chalinochromis cyanophleps occurs at depths between 6 and 45 m in rocky habitats along the Tanzanian coast of Lake Tanganyika,from Mvuna Island south to Kalala Island, a stretch of about 90 km. Field observations were made of specimens up to 18 cm total length. The COI DNA barcode sequence differs by 1.8% from that of C. popelini.

    Danio htamanthinus (Teleostei: Cyprinidae), a new species of miniature cyprinid fish from the Chindwin River in Myanmar2016In: Zootaxa, ISSN 1175-5326, E-ISSN 1175-5334, Vol. 4178, no 4, p. 535-546Article in journal (Refereed)
    Abstract [en]

    Danio htamanthinus, new species, is described from small streams in the vicinity of Htamanthi on the middle Chindwin River. It is most similar to D. choprae and D. flagrans from the Ayeyarwaddy River drainage, sharing the same elaborate colour pattern with dark vertical bars and a red interstripe along the posterior side, but is distinguished by the absence of a P+1 stripe and presence of a P stripe represented only by small spots. The uncorrected p-distance in the mitochondrial COI gene separates D. htamanthinus from D. choprae by 4.3% and from D. flagrans by 7.5%. The largest specimen is only 22.9 mm in standard length (male holotype), but the holotype and one other male, 19.5 mm SL, feature sex-specific pectoral-fin tubercles, and a female as small as 16.6 mm SL has ripening ova.In a phylogenetic analysis based on COI sequences, D. htamanthinus is sister taxon of D. flagrans+D. choprae, and those three species are sister group of D. margaritatus+D.erythromicron.

    The real Devario browni from the Irrawaddy River basin, and the new Devario ahlanderi from the Salween River basin in Myanmar (Teleostei: Cyprinidae: Danioninae)2022In: Zootaxa, ISSN 1175-5326, E-ISSN 1175-5334, ISSN 1175-5326, Vol. 5100, no 1, p. 54-72Article in journal (Refereed)
    Abstract [en]

    Specimens of Devario from a tributary to the Salween River in Myanmar initially identified as Devario browni but witha different colour pattern, were subjected to a comparative morphological analysis with syntypes and other specimens of D. browni from near its putative type locality. The Salween sample was recognised as representing a distinct species, here named Devario ahlanderi. No significant morphometric differences were found between D. ahlanderi and D. browni.The type series of Devario ahlanderi differed from D. browni and most other species of Devario in the presence of 14 vs 12 circumpeduncular scale rows. Devario ahlanderi, D. browni, and D. fangae shared subadult colour pattern. Adult D. ahlanderi differed from adult D. browni in the trunk colour pattern, consisting of rows of dark blotches or short vertical bars. In D. browni, the flank colour pattern consisted of horizontal dark stripes, the middle of which (the P stripe) frequently diverged anteriorly, enclosing a small light blotch. Specimens previously reported as D. browni from the upper Salween River basin in Yunnan differed slightly in colour pattern, and may represent a distinct species. Devario ahlanderi shared spotted colour pattern with that of one ontogenetic state in D. kysonensis, except that a row of spots marking the P-1 stripe in D. kysonensis was absent in D. ahlanderi. The minimum genetic distance between D. ahlanderi and congeneric species varied from 2.1 to 5% in the mt-coI gene.

    Description of Neolamprologus timidus, new species, and review of N. furcifer from Lake Tanganyika (Teleostei: Cichlidae)2013In: Ichthyological Exploration of Freshwaters, ISSN 0936-9902, Vol. 24, no 4, p. 301-328Article in journal (Refereed)
    Abstract [en]

    Neolamprologus timidus, new species, is described from Ulwile Island and adjacent localities on the Tanzanian coast of Lake Tanganyika. The species was observed or collected along about 100 km of coastline from KolwePoint, Cape Mpimbwe, south to Kisi Island. It is distinguished from the most similar species, N. furcifer, by presenceof scales on most of the cheek, long pectoral fin and pelvic fin with the second ray longer than the first. Neolamprologus timidus is sympatric with N. furcifer at Kolwe Point and south to Kampempa Point, and at Lupitaand Ulwile Islands south to Kisi Island, but N. furcifer is otherwise absent from the range of N. timidus. Two morphologically distinct forms are recognized in N. furcifer. Samples of N. furcifer from Ulwile Island and slightly more southern localities possess a caudal fin with rounded lobes and long middle rays, appearing onlyslightly emarginate. Samples of N. furcifer from Udachi and nearby localities possess pointed caudal-fin lobeswith greatly elongated streamers, similar to N. timidus and to N. furcifer from other parts of Lake Tanganyika, including the type specimens from the southern part of the lake. The variation in caudal-fin shape may be an expression of character displacement as it occurs in the area of sympatry between N. timidus and N. furcifer. MitochondrialDNA sequences are nearly identical in samples of N. furcifer with pointed or rounded caudal fin. A molecular phylogenetic analysis of a large set of lamprologin cichlids using two mitochondrial genes corroborates earlier analyses and places N. furcifer and N. timidus in different clades with different species of Neolamprologus, Julidochromis, Chalinochromis, and Telmatochromis despite sharing a unique combination of fin and bodyshape, and colour pattern. A 4648 base-pair multiloci analysis of a smaller number of species using fragments ofthree mitochondrial and two nuclear genes resolves N. furcifer and N. timidus in sister clades, but the N. timidus clade also includes Telmatochromis brachygnathus, and N. furcifer is sister species of Chalinochromis brichardi.

    Laubuka tenella, a new species of cyprinid fish from southeastern Bangladesh and southwestern Myanmar (Teleostei, Cyprinidae, Danioninae)2018In: ZooKeys, ISSN 1313-2989, E-ISSN 1313-2970, Vol. 742, p. 105-126Article in journal (Refereed)
    Abstract [en]

    Laubuka tenella is a new species characterized by the colour pattern, consisting of short dark verticalbars anteriorly on the side, and a dark lateral band posteriorly on the side, combined with a relativelyshort pelvic fin and 29–30 lateral-line scales. It is separated from other   analysed by minimum9 % uncorrected p-distance in the mitochondrial COI gene. The type series is composed of specimens from small streams in the Cox’s Bazar District in Bangladesh (the type locality), and the Thandwe River drainage in western Myanmar. Laubuka brahmaputraensis is strongly indicated to be a junior synonymof L. laubuca, the second known species of Laubuka in Bangladesh. Eustira ceylonensis, currently in thes ynonymy of Devario malabaricus, is a valid species of Laubuka.

    The identity of Osteobrama cotio and the status of "Osteobrama serrata" (Teleostei: Cyprinidae: Cyprininae)2018In: Zootaxa, ISSN 1175-5326, E-ISSN 1175-5334, Vol. 4504, no 1, p. 105-118Article in journal (Refereed)
    Abstract [en]

    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 aregenetically 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, statedto be distinguished from O. cotio by the presence of a serrated third dorsal-fin ray. The description of “O. serrata” doesnot fulfil requirements of the International Code of Zoological Nomenclature, (International Commission on ZoologicalNomenclature 1999) and the name is thus unavailable. Published DNA sequences of “Osteobrama serrata” are identicalto sequences of O. cotio from Bangladesh. As mentioned already in the original description, O. cotio has a serrated third dorsal-fin ray.

    Danio annulosus, a new species of chain Danio from the Shuvolong Falls in Bangladesh (Teleostei: Cyprinidae: Danioninae)2015In: Zootaxa, ISSN 1175-5326, E-ISSN 1175-5334, Vol. 3994, no 1, p. 53-68Article in journal (Refereed)
    Abstract [en]

    Danio annulosus, new species, is described from a small pool below the Shuvolong Falls in the Kaptai Lake system in Bangladesh. It shares with chain danios (D. assamila, D. dangila, D. catenatus, D. concatenatus, and D. sysphigmatus) a colour pattern consisting of series of dark rings with light interspaces along the side, complete lateral line, 14 cir-cumpeduncular scales, a produced first ray in the pectoral fin, and a black humeral spot. It differs from other chain danios in possessing much shorter pectoral and pelvic fins, and a humeral spot that is slightly wider than deep instead of round or deeper than wide. The mitochondrial cytochrome c oxidase subunit I (COI) sequence separates D. annulosus from the most similar species, D. catenatus by a p-distance of 3.4%. Although recorded from only a single locality, Danio annulosus is expected to have a wider distribution in the Karnafuli River drainage

    Devario in Bangladesh: species diversity, sibling species, and introgression in danionin cyprinids (Teleostei: Cyprinidae: Danioninae2017In: PLOS ONE, E-ISSN 1932-6203, p. 1-37, article id 12(11): e0186895Article in journal (Refereed)
    Abstract [en]

    Four species of Devario are recorded from Bangladesh: D. aequipinnatus, D. anomalus, D. coxi, new species, and D. devario. Devario aequipinnatus has a wide distribution in northern India and Bangladesh. Devario coxi, from southeastern Bangladesh near Cox’s Bazar, differs from D. aequipinnatus in mtDNA (COI, p-distance 1.8%), colouration, proportional measurements, and meristics. The minor morphological differences and low frequency of overlapping meristics suggest relatively recent separation of D. coxi from other D. aequipinnatus. Devario anomalus occurs only in southeastern Bangladesh and is here reported from localities in addition to the type locality. It differs from the similar D. xyrops in adjacent Myanmar by slender body shape and by 2.3% p-distance in the COI gene. Specimens of D. anomalus from the Sangu River were found to have the mitochondrial genome of D. aequipinnatus from Bangladesh, but agree with other D. anomalus in the nuclear RAG1 gene. Devario devario has a wide distribution on the Indian Peninsula and border regions; in Bangladesh it is restricted in distribution to the Ganga, Brahmaputra, and Meghna drainages. Reports of D. assamensis and D. malabaricus from Bangladesh are misidentifications. Perilampus ostreographus M’Clelland, 1839, is tentatively synonymized with D. aequipinnatus. Phylogenetic analysis of 14 species of striped devarios based on the COI gene results in a polytomy with four unresolved clades. Devario deruptotalea from the Chindwin basin is the sister group of D. aequipinnatus+D. coxi. Devario devario is the sistergroup of D. xyrops+D. anomalus.

    Why is Pseudophromenus cupanus (Teleostei: Osphronemidae) reported from Bangladesh, Indonesia, Malaysia, Myanmar, and Pakistan?2015In: Zootaxa, ISSN 1175-5326, E-ISSN 1175-5334, Vol. 3990, no 4, p. 575-583Article in journal (Refereed)
    Abstract [en]

    The native distribution of the small labyrinth fish species Pseudosphromenus cupanus includes southern India and Sri Lanka. According to literature it has a range including also Pakistan, Bangladesh, Myanmar, Malaysia, and Indonesia (Sumatra) but there are no voucher specimens or reliable observations from those areas. The distribution record of P. cupanus was inflated partly by including P. dayi as a synonym. Pseudosphronemus dayi is native to the Western Ghats in India, but the origin of the aquarium importation in 1907 was reported as both Cochin (=Kochi) and Malacca (=Malaysia), the latter locality obviously in error. The basis for the Sumatra record is an obviously mislabeled sample of P. dayi from Pulau Weh close to Sumatra. The basis for reporting the species from Pakistan, Myanmar or Bangladesh could not be located. Misidentified museum specimens from Myanmar and Pakistan identified as P. cupanus were never published on. Pseudosphromenus cupanus has been considered recently to be extinct in Bangladesh, but in fact it never occurred there.

    The taxonomic status of grass snake, Natrix natrix (Linnaeus, 1758)(Squamata: Colubridae), with designation of a neotype2020In: Zootaxa, ISSN 1175-5326, E-ISSN 1175-5334, Vol. 4853, no 1, p. 99-108Article in journal (Refereed)
    Abstract [en]

    As part of an investigation into the status of the near threatened Gotland grass snake, Natrix natrix gotlandica Nilson &Andrén, 1981, endemic to the island of Gotland, we discovered that Linnaeus’ type series of the common grass snake,Natrix natrix (Linnaeus, 1758), is comprised of specimens from three different currently recognized species.To stabilize the usage of the name Coluber natrix, we investigate Linnaeus’ type series, and a specimen whichLinnaeus in 1741 examined west of the Swedish city of Nyköping is designated lectotype. The lectotype has since beenlost, and a newly collected specimen from the same locality is designated neotype for Coluber natrix. The neotypeis deposited in the herpetology collection of the Swedish Museum of Natural History in Stockholm, Sweden, catalognumber NRM 8260.

    Multiple origins of stone loach, Barbatula barbatula (Teleostei: Nemacheilidae), in Sweden based on mitochondrial DNA2018In: Journal of Applied Ichthyology, ISSN 0175-8659, E-ISSN 1439-0426, Vol. 34, no 1, p. 58-64Article in journal (Refereed)
    Abstract [en]

    Stone loach, Barbatula barbatula, occurs in scattered localities in Sweden. Some of thepopulations have usually been considered as feral descendants of escaped 18thCentury pond stock, but historical documentation is inconclusive. Using the mitochondrialCOI gene as a marker, we analyzed specimens from seven Swedish localities. Oneof the middle Swedish localities, in Stockholm, belongs to a haplotype found also inPoland and Lithuania. Two other samples, from near Nyköping and Lake Hjälmaren,belong to a haplotype found in northeastern Europe (Finland, Estonia, Latvia, Volgabasin in Russia). Those two Swedish populations are probably descendants from atleast two introductions, probably for pond rearing for human consumption. Samplesfrom Skåne and Halland in southern Sweden belong to the haplotype found inDenmark, northern Germany and Poland; and whereas it remains possible that theyalso represent feral populations, they may be naturally occurring, having reachedSweden during the Ancylus period, about 8,000–10,000 years ago. A recently discoveredpopulation from the central South Swedish Highlands belongs to a mainly southeastern European haplotype. It probably represents a release of imported aquariumspecimens or live bait carried by sport fishing tourists.

    First records of Croaking Gourami, Trichopsis vittata (Cuvier, 1831)(Teleostei: Osphronemidae), from Myanmar and Bangladesh2017In: Check List: the Journal of Biodiversity Data, E-ISSN 1809-127X, Vol. 13, no 4, p. 81-85Article in journal (Refereed)
    Abstract [en]

    The Croaking Gourami, Trichopsis vittata (Cuvier, 1831), is native to Southeast Asia and Sundaland, with introductionsreported from USA, Philippines and India. The species was found by us in Myanmar (1997 and 2013), andBangladesh (2014 and 2016). DNA analysis supports the view that T. vittata is a species complex. Specimens fromBangladesh, Myanmar and the European aquarium trade are the same genotype as specimens from Thailand, possiblycorresponding to Trichopsis harrisi Fowler, 1934, considered a synonym of T. vittata. Non-native populations arelikely due to release from aquarium specimens.

    Garra mini, a new small species of rheophilic cyprinid fish (Teleostei: Cyprinidae) from southeastern hilly areas of Bangladesh2016In: Ichthyological Exploration of Freshwaters, ISSN 936-9902, Vol. 27, no 2, p. 173-181Article in journal (Refereed)
    Abstract [en]

    Garra mini, new species, is described from the Shuvolong, Shailopropat and Chingthong waterfalls in the Kar-nafuli and Sangu River drainages. The largest specimens recorded is 46.8mm SL and specimens over 40mm SL have reached reproductive size. Alongside G.ethelwynnae (28mm SL) and G.poecilura (44.5mm SL), G.miniis one of the smallest species in the genus. Garra mini is diagnosed by morphological and meristic characters in combination, particularly the numerous small predorsal scales and the presence of a contrasted dark stripe along the middle of the side, and also by the DNA barcode sequence (cytochrome oxidase subunit I, COI) with three unique substitutions

    Conjectures and refutations: Species diversity and phylogeny of Australoheros from coastal rivers of southern South America (Teleostei: Cichlidae)2022In: PLOS ONE, E-ISSN 1932-6203, Vol. 17, no 12, p. e0261027-e0261027Article in journal (Refereed)
    Abstract [en]

    Morphological and genetic analyses of species of Australoheros focusing on those distributed in coastal rivers from the Rio de La Plata north to the Rio Buranhém, support recognition of 17 valid species in the genus. Eight species are represented in coastal rivers: A. acaroides, A. facetus, A. ipatinguensis, A. oblongus, A. ribeirae, and A. sanguineus are validated from earlier descriptions. Australoheros mboapari is a new species from the Rio Taquari in the Rio Jacuí drainage. Australoheros ricani is a new species from the upper Rio Jacuí. Specimens from the Rio Yaguarón and Rio Tacuary, affluents of Laguna Merín, and tributaries of the Rio Negro, tributary of the Rio Uruguay are assigned to A. minuano pending critical data on specimens from the type locality of A. minuano. Australoheros taura is ajunior synonym of A. acaroides. Australoheros autrani, A. saquarema, A. capixaba, A.macaensis, A. perdi, and A. muriae are junior synonyms of A. ipatinguensis. Heros autochthon, A. mattosi, A. macacuensis, A. montanus, A. tavaresi, A. paraibae, and A. barbosae,are junior synonyms of A. oblongus. Heros jenynsii is a junior synonym of A. facetus.

    Review and phylogeny of the New Zealand hagfishes (Myxiniformes: Myxinidae), with a description of three new species2015In: Zoological Journal of the Linnean Society, ISSN 0024-4082, E-ISSN 1096-3642, Vol. 174, no 2, p. 363-393Article in journal (Refereed)
    Abstract [en]

    Hagfishes from New Zealand are reviewed and a phylogeny proposed using morphological and genetic data (DNA sequences of cytochrome c oxidase subunit I gene, COI, and the small subunit RNA, 16S). Eptatretus cryptus sp. nov. was previously confused with Eptatretus cirrhatus (Forster in Bloch & Schneider, 1801) because of their similar morphology, and is found from the Three Kings Islands to Stewart Island and in the eastern part of the Chatham Rise (at depths of 96–922 m). Eptatretus poicilus sp. nov. is endemic to the Three Kings Islands, where it is common and associated with soft sediment and deep-sea coral-sponge habitats (114–842 m). Neomyxine caesiovitta sp. nov. is a slender hagfish found along the east coast of the North Island south to the Chatham Rise (430–1083 m). A neotype is erected for E. cirrhatus (type locality: Breaksea Sound, Fiordland), occurring widely in New Zealand coastal, shelf, and slope waters (1–922 m), but not at the Three Kings Islands. Eptatetrus goliath Mincarone & Stewart, 2006, Neomyxine biniplicata (Richardson & Jowett, 1951), and Nemamyxine elongata Richardson, 1958 are further described using additional material. Rubicundus eos (Fernholm, 1991) is still only known from the holotype (type locality: Challenger Plateau). Genetic results showed that the New Zealand Eptatretus species form a monophyletic group within the subfamily Eptatretinae, indicating likely speciation from a single common ancestor within the area. Eptatretus poicilus sp. nov. is the sister species of E. cirrhatus, and E. cryptus sp. nov. is closely associated with the clade formed by these two species. Eptatretus goliath is most closely associated with Eptatretus minor Fernholm & Hubbs, 1981 (Gulf of Mexico), these two species basally diverging within New Zealand hagfishes. The endemic genus Neomyxine forms a well-supported monophyletic group of as yet uncertain position within the phylogenetic tree. A key to the New Zealand hagfishes, fresh colour photographs, distribution maps, and in situ video recordings are presented
