Complete mitogenome of Uca rosea and Uca paradussumieri, and their implications in evolution history of fiddler crab in Ocypodidae

Abstract

We determined the complete mitogenomes of two fiddler crabs Uca rosea (15,643 bp) and Uca paradussumieri (15,614 bp) of Ocypodidae within Brachyura. Both consist of 37 genes (13 protein-coding genes (PCGs), two ribosomal RNA genes, 22 transfer RNA genes and one control region). The mitogenomes composition of U. rosea and U. paradussumieri are highly A + T biased, 70.77% and 71.12%, respectively, and showed positive AT (0.03 and 0.02) and negative GC (−0.29 and −0.24) skews. Phylogenetic analysis showing all the fiddler crabs were under monophyletic group relationship and belong to Ocypodidae; U. rosea has a sister group relationship with U. paradussumieri.
