TL;DR: A new species of Platydoras birindellii is described from the rio Xingu Basin, Brazil, commonly found in rocky clearwater rapids and apparently endemic to the middle and upper portions of the Xingu draining the Brazilian Shield.
Abstract: A new species of Platydoras is described from the rio Xingu Basin, Brazil. Platydoras birindellii is distinguished from congeners by having gas bladder simple (vs. with posterior secondary chamber) and dorsal and caudal fins uniformly dusky (vs. with distinct marks composed of dark broad band or blotch on central portion of dorsal fin and pair of dark broad stripes on caudal fin, one central to each lobe). Platydoras birindellii shares a simple gas bladder with the sister taxon to Platydoras,Centrochir crocodili, a monotypic genus endemic to the Magdalena Basin. With respect to the caudal skeleton, the parhypural is incompletely fused to hypurals 1+2 in P. birindellii, a condition that is intermediate between those of Centrochir (parhypural typically separated from hypurals 1+2 by distinct suture) and Platydoras (parhypural typically fully fused to hypurals 1+2). Platydoras birindellii is commonly found in rocky clearwater rapids and apparently endemic to the middle and upper portions of the Xingu draining the Brazilian Shield.

TL;DR: The complete mitochondrial genome of Striped raphael catfish, Platydoras armatulus, is determined by next generation sequencing of genomic DNA without prior sample processing or primer design to enriched catfish molecular resources that are valuable for phylogenetic analysis and species identification studies.
Abstract: Striped raphael catfish, Platydoras armatulus, belongs to catfish family Doradidae, which are endemic to South America and featured by a single row of thorny scutes along the lateral line. In this study, we determined the complete mitochondrial genome of P. armatulus by next generation sequencing of genomic DNA without prior sample processing or primer design. Bioinformatics analysis provided the full-length mitogenome sequence of 16,470 bp. The P. armatulus mitogenome is composed of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes and 1 control region, showing typical circular molecule structure as in other vertebrates. The whole genome base composition was estimated to be 30.9% A, 25.2% T, 15.9% G and 28.0% C, with A/T bias of 56.1%. The generation of P. armatulus mitogenome sequence enriched catfish molecular resources that are valuable for phylogenetic analysis and species identification studies.
