Description Bariliine fishes are important components of the ornamental as well as subsistence fishery sectors in India. Many
of the species in the genus Barilius are threatened by habitat loss and therefore need to be met with conservation
initiatives. Effective conservation measures, however, require clarification of species identities and resolution of
the validity of many species currently treated as synonymous or sub-species. The complete mitochondrial
genome data provide better insight into phylogenetic information than the short fragment or single gene based
analysis. Thus, we have sequenced the complete mitochondrial genome of Barilius malabaricus, one of the important
fish species in the fresh water ornamental sector, for better understanding its phylogenetic status. The
16,519 bp mitochondrial genome consists of 37 genes which classifies as 22 tRNA, 13 protein coding and 2
ribosomal RNA genes and a control region. Overall, the mitochondrial genome bears the typical gene order and
composition as in other fishes. Further, the COI, cytochrome b and 16S rRNA gene sequences revealed that, B.
malabaricus is genetically closer to B. canarensis and B. bakeri compared to other Barilius species. Also, the Barilius
species of west flowing rivers in Western Ghats were consistently recovered as a clade distinct from other species.
We therefore suggest to retain the genus name Barilius for the species from the Western Ghats until a comprehensive
analysis based on both morphological and molecular markers reveals the relationship between species
now variously placed in the genera Barilius and Opsarius in greater detail.
