Complete mitochondrial genome of the pearly razorfish Xyrichtys novacula: phylogenetic analysis of its placement within the Labridae family

Abstract

In this paper, we report the complete mitochondrial genome (17,306 bp) of the pearly razorfish Xyrichtys novacula Linnaeus, 1758, a labrid that inhabits tropical and temperate Atlantic waters and the Mediterranean Sea. The circular double-stranded sequence contains the typical teleost gene order with 13 protein-coding genes, 22 tRNA, 2 rRNA, 1 control region, and 2 intergenic spacers between the rRNAs. Using the sequences of all protein-coding genes, we inferred the phylogeny for the Labriade family using 24 labrids and 3 outgroup species that placed X. novacula in a monophyletic group including species from the Pseudocheilines, Pseudolabrines, and Julidines.
