“…This result confirmed that Geosesarma belongs to Grapsoidea, Sesarmidae, congruent with the morphological assignments (Ng et al, 2008;Ng, 2017;Ng and Wowor, 2019;Shy and Ng, 2019). All Sesarmidae species cluster into a clade consisting of two sister groups, which was consistent with previous findings (Wang et al, 2019;Li et al, 2020;Lu et al, 2020; Sesarmidae species are most closely related to Gecacinidae, constituting part of the Grapsoidea group, which is in accordance with the results of the studies by Chen et al (2019), Wang et al (2019), Lu et al (2020), and. The mitochondrial phylogenomic analyses including our dataset have shown the divergent phylogenetic status of Grapsidae and Dotilidae (Wang et al, 2019;Li et al, 2020;.…”

“…Nevertheless, the BI tree placed Grapsidae and Dotilidae group at the basal to the ((((Sesarmidae) + Gecarcinidae) + Xenograpsidae) + Ocypodidae) clade. While ML tree recovered Dynomenidae + [Homolidae + (Raninidae)] relationship that was similar to those reported in the studies by Lu et al (2020) and , BI tree exhibited Homolidae + [Dynomenidae + (Raninidae)] topology. The presence of only one or a small number of representatives for certain families could have resulted in unstable phylogenetic relationships.…”

“…Four PCGs (nd5, nd4, nd4L, and nd1), eight tRNAs (tRNA His , tRNA Phe , tRNA Pro , tRNA Leu , tRNA Val , tRNA Gln , tRNA Cys , and tRNA Tyr ), and two rRNAs (12S and 16S rRNA) are encoded on the light strand. The overall base composition is 34.91% A, 17.29% C, 10.93% G, and 36.87% T, with 71.78% A þ T, which is similar to the base content and AT bias of mitochondrial genomes in other Crustacea (Xing et al 2017;Lu et al 2020;Wang et al 2020).…”

The complete mitochondrial genome of Chionoecetes japonicus was sequenced using a specimen collected offshore in the East Sea. The genome includes 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, two ribosomal RNA (rRNA) genes, and a control region (D-loop), with a total length of 16,060 bp. The overall nucleotide composition was 34.91% A, 17.29% C, 10.93% G, and 36.87% T, with 71.78% A þ T. In the phylogenetic tree was constructed using maximum-likelihood and Bayesian inference analyses, C. japonicus and C. japonicus pacificus formed a genetic clade that was sister to C. opilio.

New insights into the evolution of portunoid swimming crabs (Portunoidea, Heterotremeta, Brachyura) and the brachyuran axial skeleton

Portunoidea (Heterotremata) represents a morphologically disparate taxon of true crabs (Brachyura), best-known for many of its representatives being considered as “swimming crabs”. This term, however, sometimes refers to a distinct taxon (traditionally to Portunidae within Portunoidea), but sometimes also to a certain morphotype, with the 5th pereiopod (P5) having the shape of a specific swimming leg. We herein use the term “P5-swimming crab” or “P5-swimmer”, not only to restrict it to the morphotype, but also to distinguish it from other kinds of swimming in Brachyura. The evolution of P5-swimming crabs is still poorly investigated. For example, it is not known, whether the morphotype evolved several times independently in different lineages of Portunoidea or if it evolved only once and had been lost in several lineages. We here present the first approach combining molecular with morphological data resulting in a new phylogenetic hypothesis of Portunoidea. For the first time, the latter involve data from the axial skeleton and extrinsic musculature. Morphological examinations revealed that axial skeleton and extrinsic musculature in P5-swimming crabs were more diverse than previously thought, except for the origin of the P5 anterior coxa muscle origin at the median plate, which was present in all P5-swimmers. Ancestral state reconstructions based on parsimony revealed that the stem species of Portunoidea already showed the morphotype of a P5-swimming crab, but with a long merus which probably resulted in a less effective P5-swimming ability compared to that of extant P5-swimming crab species with short merus. Several other extant taxa represent a reversal of the P5-swimmer morphotype with variable degree, with some extant species showing a complete reversal of unambiguous P5-swimming crab character states, like for example the common shore crab Carcinus maenas. Finally, a missing connection of interosternite 7/8 to the sella turcica (the secondary loss of the “brachyuran sella turcica”) in the stem species of Heterotremata, resulting in a junction plate forming a cavity that offered room and attachment sites for the P5 extrinsic musculature is uncovered as preadaptation to the P5-swimmer morphotype in Heterotremata, which is missing in “Podotremata" and Thoracotremata, the other two traditional main taxa of Brachyura.
