Mitocondrial COI and 16S rDNA sequences support morphological identification and biogeography of deep-sea red crabs of the genus Chaceon (Crustacea, Decapoda, Geryonidae) in the Eastern Central and South Atlantic Ocean. [PDF]
PLoS ONE, 2019 The geographical spreading of new fishing activities and the increasingly deeper locations of these activities have shown the worldwide distribution of gerionid crabs and new descriptions of Chaceon taxa.

Molecular phylogenetics of swimming crabs (Portunoidea Rafinesque, 1815) supports a revised family-level classification and suggests a single derived origin of symbiotic taxa [PDF]
PeerJ, 2018 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

Decapod Crustacea of the Central Paratethyan Ottnangian Stage (middle Burdigalian): implications for systematics and biogeography [PDF]
Geologica Carpathica, 2015 Decapod crustaceans from the Ottnangian (middle Burdigalian, Lower Miocene) of the Western and Central Paratethys remain poorly known. In this study, we review and re-describe mud shrimps (Jaxea kuemeli), ghost shrimps (Gourretia sp., Calliax michelottii)

Occurrence of Chaceon fenneri (Manning & Holthuis) (Crustacea, Brachyura, Geryonidae) in the Northeast of Brazil [PDF]
Revista Brasileira de Zoologia, 2001 Chaceon fenneri (Manning & Holthuis, 1984), so far known only from the offshore region of Florida, was collected off the Northeast of Brazil. A discussion on the variation within the species and morphometric data of the specimens examined are also given.

The Family Geryonidae (Decapoda, Brachyura) in the Canary Islands
Crustaceana, 1996 AbstractAn account of the species of the family Geryonidae recorded from the Canary Islands is given. Chaceon maritae and Geryon trispinosus are recorded for the first time from the Canaries. Whenever available, data on distribution, habitat, biometry, length/width and length/weight relationships, reproduction, other bioecological information, and ...

OCCURRENCE OF CHACEON AFFINIS (DECAPODA: GERYONIDAE) IN THE VICINITY OF A HYDROTHERMAL VENT SITE ON THE MID-ATLANTIC RIDGE [PDF]
Journal of Crustacean Biology, 2000 Abstract Observations of Chaceon affinis, from the French deep submersible Nautile, were made at the Menez Gwen hydrothermal vent site (Mid-Atlantic Ridge, 37°50′N) in June 1994. This was the first time that specimens of this species were seen in the inner periphery of an active vent field.
