Complete mitochondrial genomes of three troglophile cave spiders (Mesabolivar, pholcidae)

Abstract

In this study, we report the first complete mitochondrial genome of three Mesabolivar specimens found in the interior of N4E_0023 cave from Serra Norte (Carajás), Parauapebas (Brazil). The three mitogenomes contain 14,941, 14,845 and 14,727 bp, and GC content of 29.41%, 31.68% and 29.34%, respectively. All three mitogenomes include 13 protein-coding genes, 17 transfer RNA (tRNA) genes, five putative transfer RNA (tRNA) genes and two ribosomal RNA (16S and 12S rRNA). We also performed a phylogenetic analysis with the concatenated coding genes from the complete mitochondrial genomes and showed that the analyzed Mesabolibar specimens clustered together in a clade, sister to the group with two Pholcus species, the other Pholcidae species with available mitogenome.
