The complete mitochondrial genome of (Günther, 1868) (Ostariophysi: Characiformes: Anostomidae): an aquarium headstander.

, commonly known as marbled headstander, is an important freshwater aquarium fish from Brazil, found in the Orinoco, Amazon, Paraguay and lower Parana River basins. This genus has only two species and only this species occurs in Brazil. The complete mitochondrial genome of is 16,685 bp in length and it includes 13 protein-coding genes (PCGs), 2 rRNAs, 22 tRNAs genes and a control region with 1,028 bp. It has two PCGs with GTG start codon and the others with ATG start codon. Four of the 13 PCGs appear TAA stop codon, three incomplete TA_ stop codon, four incomplete T_ _ stop codon, one contain AGG stop codon and one TAG stop codon. Phylogenetic analysis showed that formed a sister group of (AP011994.1), thus maintaining the Family Anostomidae as a clade.
