Recent fossil calibrated molecular phylogenies have revealed that the Brachyura underwent rapid radiation during the Cretaceous and Early Tertiary, resulting in many early diverging lineages separated by short internodes that remain difficult to resolve.

Brachyura is one of the most species rich and highly derived groups among extant crustaceans, with over 7250 known species. However, brachyuran phylogeny remains controversial and requires further study. Here, we combined 103 brachyuran mitogenomes from

Molecular methods are playing an increasingly important role in reconstructing phylogenetic relationships. Regardless of what source of DNA is used, the simple idea behind it is that the genetic distance (distinctness of DNA sequences) between any two

Eubrachyurans are currently divided into two subsections based on the anatomical position of the seminal duct termini. Heterotremes have the seminal ducts passing through the pereiopod 5 coxae, emerging externally in the form of " penes" to contact the
