Phylogeny of eriphioid crabs (Brachyura, Eriphioidea) inferred from molecular and morphological studies

摘要

Eriphioid crabs occupy a diverse range of habitats from intertidal rocky shores, mangrove swamps, coral reefs and the continental slope to depths below 800 m. Most of these crabs are of moderate size with the exception of Hypothalassia armata (De Haan, 1835) and Pseudocarcinus gigus (Lamark, 1818), both of which are large with the latter weighing 12 kg or more and growing up to 40 cm in carapace width. Larval development varies between five zoeal stages, for example, as for P. gigas (see Gardner & Quintana 1998), and four as reported by Wear (1968) and Wear and Fielder (1985) for Ozius truncatus H. Milne Edwards, 1834.
