A new species of Hemiodus is described from the Rio Xingu basin, Pará, Brazil. It distinguished congeners by combination presence a dark longitudinal stripe extending head to tip lower caudal-fin lobe, an oblique blotch on dorsal-fin, 9–11 scale rows above lateral line, 58–66 perforated line scales, and 17–20 circumpeduncular scales. Comments conservation status species, as well its relationships among are made.
Salamanders are the only living tetrapods capable of fully regenerating limbs. The discovery salamander lineage-specific genes (LSGs) expressed during limb regeneration suggests that this capacity is a novelty. Conversely, recent paleontological evidence supports deeper evolutionary origin, before occurrence salamanders in fossil record. Here we show lungfishes, sister group tetrapods, regenerate their fins through morphological steps equivalent to those seen salamanders. Lungfish de novo...
A new species of the curimatid genus Cyphocharax is described from Rio Xingu, Amazon basin. This readily distinguished congeners by presence a dark, round blotch on caudal peduncle and high density iridophores ventrolateral portion body, resulting in strongly countershaded pattern. Molecular phylogenetic analyses support recognition suggest that it nested within Curimatella alburna clade. Ancestral state reconstruction suggests independent evolutionary origins blotched flanks among fishes.
Abstract Hemiodus is the largest genus of South American freshwater fish family Hemiodontidae, with 23 valid species. However, species‐level diversity remains uncertain since morphological studies have indicated additional Also, phylogenetic relationships among species and boundaries within this are still unresolved. Herein, we sequenced barcode (COI) gene 19 on which undertook molecular delimitation methods (automatic gap discovery [ABGD], generalized mixed Yule coalescent [GMYC] Poisson...
ABSTRACT A good taxonomic assessment of specimens is an essential task to many biological studies and DNA data have provided additional sources information assist in the disentanglement problems among living organisms, as has been case some taxa megadiverse Neotropical ichthyofauna. Here we assessed all valid species freshwater fish genera Anodus, Argonectes, Bivibranchia Micromischodus family Hemiodontidae establish molecular boundaries them. All delimitation methods defined exactly only...
Hemiodus bimaculatus sp. nov., is described from tributaries of the Rio Juruena and Teles Pires in upper Tapajós basin. The new species diagnosed most congeners, except jatuarana , by having a conspicuous circular or horizontally elongate dark blotch on caudal peduncle ( v . inconspicuous H. iratapuru absent other species). differs round midlateral spot flank ), 98–121 perforated scales lateral line 66–72 23–28 scale series above 14–19 below 12–13 6–7 ). hypothesised to be related microlepis...
The complete mitochondrial genomes of the whip spiders Charinus carajas, C. ferreus, and Heterophrynus longicornis were sequenced, annotated, compared with other mitogenomes arachnids. three new have 37 genes usually observed in Metazoa: 13 protein-coding (PCGs), 22 transfer RNAs (tRNAs), two ribosomal (rRNAs), plus a non-coding control region (CR). Most PCGs presented an ATN start codon, except cox1 both species, initiating TTA. terminated stop codons TAA or TAG, nad5 carajas cox3 H....
