Euryxanthops Garth & Kim, 1983

Remarks. The genus Euryxanthops Garth & Kim, 1983 , was established for three species of relatively deepwater xanthids from Japan and the Philippines, viz. E. orientalis ( Sakai, 1939) (type species by original designation), E. dorsiconvexus Garth & Kim, 1983 , and E. flexidentatus Garth & Kim, 1983 . Davie (1997) subsequently described two more species, E. latifrons and E. cepros , from the Loyalty Islands and Seychelles respectively. Euryxanthops orientalis has since been reported from Taiwan ( Ho et al. 2000). All the species are essentially deep water usually taken from depths of 200 to 600 m. The genus is characterized by a carapace which resembles members of the genus Xantho , with the dorsal surface gently convex, the regions relatively well defined, a truncate front, an anterolateral margin which has a lobiform external orbital angle and three lobiform teeth, all of which are cristate to sub-cristate, ambulatory legs which have a cristate dorsal meral margin, and dactyli which are densely setose; chelipeds which are markedly unequal in both sexes; a male first gonopod that is stout, gently curved, with the lateral surfaces covered with small spinules, and the sub-distal and distal surfaces lined with long setae; and a male second gonopod which is much shorter than the first ( Garth & Kim 1983; Davie 1997).
