| A phylogenetic analysis was conducted including representatives from all recognized extant and extinct families of the Xanthoidea sensu lato, resulting in one new family, Hypothalassiidae. Four xanthoid families are elevated to superfamily status, resulting in Carpilioidea, Pilumnoidoidea, Eriphioidea, Progeryonoidea, and Goneplacoidea, and numerous subfamilies are elevated to family status. The Mathildellidae is moved from the Goneplacidae to the Portunoidea. Diagnoses for all superfamilies and families discussed herein are provided, embracing characters typically used by biologists as well as readily fossilized features of the dorsal carapace, sternum, abdomen, and chelipeds. All genera known from the fossil record at one time referred to the Xanthidae... |

| Zovocarcinus muelleri, a new genus and species of panopeid crab, is recorded from Eocene (upper Ypresian) strata at Zovo di Bolca (Verona, northeast Italy), on the basis of a single specimen from a rich fossiliferous and coral-reef deposit in the Lessini Mountains (Verona area). |

| Identification and utilization of proxy characters in extant families has been accomplished with success for fossil members of the Calappidae, Hepatidae, Necrocarcinidae, Matutidae, and Hexapodidae. The fossil and extant Raninidae have been revised using primarily hard-part morphology preserved in the fossil record although formal designation of “proxy characters” has not occurred. Hard-part characters can also be used to differentiate among members of the Atelecyclidae and the Cheiragonidae. Thus, the method of using proxy characters is demonstrably suitable for application to a difficult group like the Xanthoidea. |

| The relative growth and size at onset of morphological sexual maturity of the stone crab Menippe nodifrons were investigated. A total of 399 crabs was captured on Praia Grande and Tenório beaches at Ubatuba. Carapace width (CW) and length, cheliped propodus length and height, abdomen width in females, and gonopod length in males were recorded. In females, the abdominal width showed negative allometry for juveniles and positive allometry for adults; the puberty molt occurred at 31.6 mm CW. In males, the size at onset of morphological sexual maturity was estimated as 29.7 mm CW; the gonopod growth showed positive allometry for juveniles, and an isometric relationship for adults. The gonopod length and the abdominal width were the most appropriate... |
