Abstract

Trimma macrophthalmus is a colorful pygmy goby that is widely associated with coral and distributed in the Indo-Pacific Ocean. Here, the complete mitochondrial genome of T. macrophthalmus was first sequenced and annotated. The entire mitogenome is a typical circular molecule (16,943 bp in total length) containing 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes, and 1 control region (CR). The overall base composition is 29.6% for A, 15.6% for G, 27.9% for C and 26.9% for T. Phylogenetic tree was reconstructed using concatenated 13 protein coding genes sequences of the 38 related taxa. The phylogenetic analysis indicated that T. macrophthalmus was most closely related to T. okinawae. These findings will contribute for further genetic studies such as evolution, DNA barcoding and molecular phylogeny of genus Trimma and related gobiid fishes.
