Hexapodid crabs are recorded from Taiwan for the first time. A new genus and new species, Latohexapus granosus, is described. Most similar to Hexapus and Hexapinus, Latohexapus can easily be distinguished by its proportionately much broader carapace with prominent granulated and well-defined regions, a very broad thoracic sternum which has a deep transverse groove between thoracic sternites 3 and 4, and a male first pleopod which extends well beyond the male telson. Paeduma orientalis (Rathbun, 1909) is also recorded from Taiwan on the basis of a female specimen.
