“…MK204361). The total nucleotide composition of this mitogenome is 38.6% for A, 16.0% for C, 9.8% for G, and 35.6% for T. The AT content (74.2%) was higher than GC content (25.8%) which is similar to other brachyuran crabs (Shi et al 2015). The circle genome contains 13 protein-coding genes (PCGs), 22 transfer (tRNA) genes, 2 ribosomal (rRNA) genes, and a control region.…”

In this study, the complete mitochondrial genome (mitogenome) sequence of Latreillia valida was determined. The circle genome was 15,097 bp in length and contains 13 protein-coding genes (PCGs), 22 transfer (tRNA) genes, 2 ribosomal (rRNA) genes, and 1 control region. The overall nucleotide composition of this mitogenome was 38.6% for A, 16.0% for C, 9.8% for G, and 35.6% for T and showed 87% identity to Moloha majora. Phylogenetic analysis showed that L. valida was clustered with Homolidae family, suggesting that Latreilliidae and Homolidae had a close relationship.

“…The initiation codons of 13 PCGs are usual ATN, but the incomplete stop codon T is assigned for three PCGs (Table 2 ). These variable start codons and incomplete stop codons (T and/or TA) are frequently found in other brachyurans ( Yamauchi et al 2003 ; Sun et al 2005 ; Shi et al 2015 ; Bai et al 2016 ), and may be completed by polyadenylation during the mRNA maturation process ( Ojala et al 1981 ; Qiu et al 2005 ).…”

“…Therefore, they are considered powerful markers for resolving ancient phylogenetic relationships ( Boore 1999 ). Nevertheless, the number of complete mitogenomes of brachyurans is limited to 52 species published to date, which is not commensurate with the extant species diversity for the Brachyura (including several species with incomplete mitogenomes; Yamauchi et al 2003 ; Segawa and Aotsuka 2005 ; Sun et al 2005 ; Ji et al 2014 ; Shi et al 2015 ; Wang et al 2016 ; Xing et al 2016 ). Meanwhile, knowledge of mitogenomes from primary freshwater crabs remains scant, and only three species have been sampled (including an incomplete sequence; Segawa and Aotsuka 2005 ; Ji et al 2014 ; Wang et al 2016 ).…”

Complete mitochondrial genomes from two species of Chinese freshwater crabs of the genus Sinopotamon recovered using next-generation sequencing reveal a novel gene order (Brachyura, Potamidae)

Recent morphological and molecular evidence has challenged classical interpretations of eubrachyuran phylogeny and evolution. Complete mitochondrial genomes of two species of potamid freshwater crabs, Sinopotamon yaanense and Sinopotamon yangtsekiense were obtained using next-generation sequencing. The results revealed a novel gene order with translocations of a five-gene block and a tRNA gene in comparison to available brachyuran mitochondrial genomes. DNA sequence comparisons position the Potamidae, a primary freshwater crab family, outside of the clade for the traditional heterotreme families, and closer to the clade that includes the thoracotreme families of grapsoid and ocypodoid crabs. Mitogenomic comparisons using rapid next-generation sequencing and a much wider taxonomic sample are required for a high-resolution examination of the phylogenetic relationships within the Eubrachyura.

“…Currently, Guinot's (1977) traditional classification of brachyurans into Podotremata, Heterotremata, and Thoracotremata (the latter two forming the Eubrachyura) is under debate and in particular, the monophyly of Podotremata and Heterotremata has been disputed (Jamieson et al 1995;von Sternberg & Cumberlidge 2001;Guinot & Quenette 2005;Ahyong et al 2007;Br€ osing et al 2007;Scholtz & McLay 2009;Karasawa et al 2011;Guinot et al 2013;Shen et al 2013;Tsang et al 2014;Shi et al 2015Shi et al , 2016.…”

The reproductive systems of crabs reveal characters of considerable importance for the understanding of brachyuran phylogeny and evolution. The Dorippoidea show several plesiomorphic characters within Eubrachyura and similarities to podotreme crabs. Hence, they are often considered as an early diverging lineage, sometimes even as the sister group to all remaining eubrachyurans. Due to their role as prime candidates for putative plesiomorphic characters of the reproductive system of the Eubrachyura, we compared the morphology of the vaginae, seminal receptacles, and ovaries of three dorippid species using histological methods, micro‐computed tomography, and 3‐D reconstructions. Despite the putative phylogenetic position of dorippids, the female reproductive system shows features that are regarded as derived characters in eubrachyurans, including a concave vagina and a ventral‐type seminal receptacle. In contrast to other eubrachyurans, the oviduct does not enter the seminal receptacle directly but through specific cuticular valves. The female reproductive systems of Dorippe sinica and Dorippe quadridens are remarkable in further aspects. The seminal receptacles of both species are completely cuticle‐lined and have accessory sperm storage structures, the bursae. Our findings on the morphology of the female reproductive system of dorippids with its unique combination of basal, derived, and new characters challenges the prevailing hypothesis on the evolution of sperm storage organs in Eubrachyura.
