Abstract: A new epialtid crab species, Thusaenys mutilioucious Chen and Lo, 2014, is redescribed on the basis of material from the Siaoliouciou Island, Taiwan. T. mutilioucious was originally described in the book of local marine education promotion (Chen and Lo, 2014), and it is confirmed that the taxon is distinct from other species of the genus Thusaenys Griffin and Tranter, 1986 by several morphological characters, such as the strongly produced preorbital lobe of supraorbital eave and the basal antennal article broad, bearing a blunt anterolateral spine etc., will be described in this report.
