          Abstract

          A systematic review of the crab genus Phlyctenodes Milne Edwards, 1862 is carried out. Based on carapace features, this taxon is placed in the subfamily Actaeinae, family Xanthidae MacLeay 1838. Species attributed to this genus are known from Eocene reef environments in Europe. Preservation of crustacean remains in this kind of environment is very rare, and it could explain scarcity of specimens of this genus. For the first time, pictures of types of this genus described during the XIX century and the first decades of the XX century are presented. A study of recently collected specimens from the Eocene of Véneto (Italy) allows to clarify relationships between Phlyctenodes krenneri Lörenthey. 1898 and P. dalpiazi Fabiani, 1911. Presence of P. tuberculosus Milne Edwards, 1862 among the new material is documented. The otherknown species of this genus, P. hantkeni Lörenthey. 1898 is placed in Pseudophlyctenodes new genus on the basis of differences in morphological features.

          Se presenta una revisión sistemática del género de cangrejo Phlyctenodes Milne Edwards, 1862. Con base en las características del caparazón, este taxon es ubicado en la subfamilia Actaeinae, familia Xanthidae MacLeay, 1838. Las especies de este género son conocidas de ambientes arrecifales en el Eoceno de Europa. La preservación de restos de crustáceos en este tipo de ambiente en muy rara, lo que podría explicar la escasez de especímenes de este género. Se presentan por vez primera fotografías de ejemplares tipo de este género descritos durante el siglo XIXy las primeras décadas del siglo XX. El estudio de especímenes recolectados recientemente en el Eoceno de Véneto (Italia) permite aclarar las relaciones entre Phlyctenodes krenneri Lörenthey, 1898, y P dalpiazi Fabiani, 1911. Se documenta la presencia de P tuberculosus Milne Edwards, 1862 entre los ejemplares recolectados. La otra especie conocida de este género, P. hantkeni Lörenthey. 1898, es ubicada en Pseudophlyctenodes nuevo género, con base en diferencias en las características morfológicas.
