    ABSTRACT: Callichirus garthi from the southeastern Pacific has long been considered as a junior synonym of Callichirus seilacheri from the eastern tropical Pacific. The present study is based on a detailed comparison between both taxa collected along the coast of Chile and the Pacific coast of Central America, including type material of C. garthi and topotypic material of C. garthi and C. seilacheri. This reveals that C. garthi is a valid species, with a suite of morphological features that allow it to be separated from C. seilacheri. Callichirus garthi can be primarily distinguished from C. seilacheri by closely-set eyestalks; proximal margin of the terminal antennular segment exceeding the proximal margin of the last antennal segment with the dorsal margins of both the basal and intermediate antennular segment setose; merus of the larger cheliped armed with a rough semicircular lobe over the anterior ventral margin and the ischium curved downwards without ornamentation on ventral margin. On the basis of the present study, we therefore resurrect C. garthi as a valid species for the Chilean and Peruvian populations.

    • "El término viejo mundo es más bien usado por historiadores, mientras que acá es más adecuado hablar de Asia, África y Europa (Morrone, 2001). Los estudios de fauna marina intermareal chilena en decápodos (Retamal & Moyano, 2010) indican la presencia de patrones de distribución definidos para el territorio continental, existiendo dos áreas, una zona chileno-peruana (18-42ºS) y una Magallánica que incluye la zona continental al sur de los 42ºS. Por otro lado, los territorios insulares comprenden dos zonas diferentes, un primer grupo conformado por el "

    ABSTRACT: The present study provided information extending the known geographical distribution of three species of majoid crabs, the epialtids Acanthonyx dissimulatus Coelho, 1993, Epialtus bituberculatus H. Milne Edwards, 1834, and E. brasiliensis Dana, 1852. Specimens of both genera from different carcinological collections were studied by comparing morphological characters. We provide new data that extends the geographical distributions of E. bituberculatus to the coast of the states of Paraná and Santa Catarina (Brazil), and offer new records from Belize and Costa Rica. Epialtus brasiliensis is recorded for the first time in the state of Rio Grande do Sul (Brazil), and A. dissimulatus is reported from Quintana Roo, Mexico. The distribution of A. dissimulatus, previously known as endemic to Brazil, has a gap between the states of Espírito Santo and Rio de Janeiro. However, this restricted southern distribution is herein amplified by the Mexican specimens.
