Complete mitochondrial genome and the phylogenetic position of the Lake Eyre hardyhead (), a freshwater atherinid fish endemic to Lake Eyre Basin, South Australia.

The Lake Eyre hardyhead () is an endemic freshwater fish living in the Lake Eyre basin in South Australia. Here, I report the full mitogenome description and the phylogenetic position of this species based on the mitogenome phylogenetics. The mitogenome is 16,602 bp-long with the standard 37 genes all included, with a genomic structure typical of a vertebrate mitogenome. A maximum likelihood phylogenetic analysis to confirm this species position was conducted, using a data set including publicly available 28 atherinomorphs, nine percomorphs, and two outgroups. The result confirms position's in Atherinoidei. The complete mitogenome data of reported here would be useful for further genetics, phylogeography, and phylogenetics studies involving this species.
