Museomics reveals the phylogenetic position of the extinct Moroccan trout Salmo pallaryi.

The authors used museomics to reconstruct the mitochondrial genome from two individuals of the Moroccan, endemic and extinct trout, Salmo pallaryi. They further obtained partial data from 21 nuclear genes previously used for trout phylogenetic analyses. Phylogenetic analyses, including publicly available data from the mitochondrial control region and the cytochrome b gene, and the 21 nuclear genes, place S.

Conjectures and refutations: Species diversity and phylogeny of Australoheros from coastal rivers of southern South America (Teleostei: Cichlidae).

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.

The taxonomic status of grass snake, Natrix natrix (Linnaeus, 1758 (Squamata: Colubridae), with designation of a neotype.

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 which Linnaeus in 1741 examined west of the Swedish city of Nyköping is designated lectotype. The lectotype has since been lost, and a newly collected specimen from the same locality is designated neotype for Coluber natrix.

Chameleonfishes in Bangladesh: hipshot taxonomy, sibling species, elusive species, and limits of species delimitation (Teleostei: Badidae).

Five species of Badidae are reported from Bangladesh, with morphological diagnoses and mitochondrial DNA sequences (cytochrome b, cytb; and cytochrome c oxidase subunit I, coi). Dario kajal is recorded from Bangladesh for the first time with a precise locality. Badis badis is reported from several localities in central Bangladesh.

Building a DNA barcode library for the freshwater fishes of Bangladesh.

We sequenced the standard DNA barcode gene fragment in 694 newly collected specimens, representing 243 species level Operational Barcode Units (OBUs) of freshwater fishes from Bangladesh. We produced coi sequences for 149 out of the 237 species already recorded from Bangladesh. Another 83 species sequenced were not previously recorded for the country, and include about 30 undescribed or potentially undescribed species.

The identity of Osteobrama cotio, and the status of "Osteobrama serrata" (Teleostei: Cyprinidae: Cyprininae).

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 new species of cyprinid fish from southeastern Bangladesh and southwestern Myanmar (Teleostei, Cyprinidae, Danioninae).

is a new species characterized by the colour pattern, consisting of short dark vertical bars anteriorly on the side, and a dark lateral band posteriorly on the side, combined with a relatively short pelvic fin and 29-30 lateral-line scales. It is separated from other analysed by minimum 9 % uncorrected -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.

Devario in Bangladesh: Species diversity, sibling species, and introgression within danionin cyprinids (Teleostei: Cyprinidae: Danioninae).

Four species of Devario are recorded from Bangladesh: D. aequipinnatus, D. anomalus, D.

Danio htamanthinus (Teleostei: Cyprinidae), a new species of miniature cyprinid fish from the Chindwin River in Myanmar.

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.

Danio annulosus, a new species of chain Danio from the Shuvolong Falls in Bangladesh (Teleostei: Cyprinidae: Danioninae).

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.

Why is Pseudosphromenus cupanus (Teleostei: Osphronemidae) reported from Bangladesh, Indonesia, Malaysia, Myanmar, and Pakistan?

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.

Chalinochromis cyanophleps, a new species of cichlid fish (Teleostei: Cichlidae) from Lake Tanganyika.

Chalinochromis cyanophleps is described from nine specimens, the largest 129 mm SL, from Namansi. It differs from other 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.

Phylogeny of the Prolecithophora (Platyhelminthes) Inferred from 18S rDNA Sequences.

Complete nuclear 18S rDNA sequences from 14 species of the Prolecithophora were obtained and used, in combination with literature data, to generate the first parsimony-based hypothesis of the phylogeny of the order Prolecithophora (Platyhelminthes). Bootstrap, parsimony jack-knife, and Bremer support values were computed and compared. The monophyly of the Prolecithophora sensu stricto and the family Plagiostomidae is strongly supported.
