The complete mitochondrial genome sequence of the karst-dwelling crab, Terrapotamon thungwa (Crustacea: Brachyura: Potamidae)

Abstract

Terrapotamon thungwa is a new species of terrestrial long-legged crab discovered in a karst landscape of southern Thailand. Here, we report the first complete mitochondrial genome of this crab species. The mitochondrial genome size is 16,156 base-pairs (bp), including 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA), and two ribosomal RNA (rRNA) genes. The AT and GC content of the mitochondrial genome sequence is 73.2% and 26.8%, respectively. Phylogenetic analysis with 26 crustacean species, based on 13 mitochondrial conserve genes, showed that T. thungwa was closely related to other freshwater crab species in the family Potamidae.
