Revision of the Carcineretidae Beurlen, 1930 (decapoda: Brachyura: Portunoidea) and Remarks on the Portunidae Rafinesque, 1815 Carrie

چکیده
All genera previously referred to the Carcineretidae are herein evaluated, and the family is restricted to three genera, Carcineretes, Cancrixantho, and Mascaranada, for which diagnoses are provided. Ophthalmoplax and Longusorbis are herein removed to the Portunidae, and Longusorbis eutychius new species is described from the Eocene Tepetate Formation of Baja California Sur, Mexico, extending the range of that genus across the K/P boundary. The placement of Ophthalmoplax into the Portunidae marks the first confirmed notice of the family in Cretaceous rocks, a major range extension for the family. Important characteristics of the Portunoidea are discussed in the context of placement of fossil taxa within the superfamily and its constituent families.

Revision of Portunoidea Rafinesque, 1815 (Decapoda: Brachyura) with Emphasis on the Fossil Genera and Families
The superfamily Portunoidea including extinct lineages is herein evaluated via cladistic analysis of adult morphological characters and traditional systematics. Nearly every fossil species has been examined via type material, or if this was not possible, through illustrations and original descriptions. The analyses indicate that the superfamily is much more diverse at the family level than has ...

متن کاملMolecular phylogenetics of swimming crabs (Portunoidea Rafinesque, 1815) supports a revised family-level classification and suggests a single derived origin of symbiotic taxa
Portunoidea is a diverse lineage of ecologically and economically important marine crabs comprising 8 families and 14 subfamilies. Closely related portunid subfamilies Caphyrinae and Thalamitinae constitute some of this group's greatest morphological and taxonomic diversity, and are the only known lineages to include symbiotic taxa. Emergence of symbiosis in decapods remains poorly studied and ...
