Abstract

Exostoma gaoligongense is an endemic glyptosternine catfish distributed in the Nujiang River drainage, Yunnan Province, China, with few published genetic information. In this study, we sequenced and characterized the complete mitochondrial genome of E. gaoligongense, which was circular, 16529 bp in length, containing 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, one replication origin and one control region. Phylogenetic analysis revealed that E. gaoligongense had the closest relationship with its congener E. labiatum. They clustered with the clade containing most genera of glyptosternine catfishes and then cluster with the more primitive genera Glaridoglanis and Glyptosternon.
