Abstract
The short-barbel gudgeon Squalidus japonicus coreanus (Teleostei, Cypriniformes, Cyprinidae) is a subspecies of S. japonicus, and is endemic to Korea. The complete mitochondrial genome sequence consisted of 16 597 base pairs (bp) encoding 13 protein-coding genes (PCGs), two ribosomal RNAs (rRNAs), 22 transfer RNAs (tRNAs), and two non-coding regions. The overall base composition of S. japonicus coreanus was G + C: 47.4% and A + T: 52.6%, apparently with a slight AT bias. Phylogenetic analysis showed that S. japonicus coreanus was closely related to Pungtungia herzi.
