Jacforus cavatus is a species of crab in the monotypic genus Jacforus in the family Xanthidae.

Description

Jacforus is a small crab, with a carapace around 5 millimetres (0.20 in) long and 7 mm (0.28 in) wide.[1]

Distribution

Jacforus cavatus has a wide distribution in the tropical Indo-Pacific, ranging from Kenya to Australia, Japan and Hawaii.[1]

Taxonomy

J. cavatus was first described by Mary J. Rathbun in 1907 as Cycloxanthus cavatus.[1] It was described again by Charles Howard Edmondson in 1925 as Euxanthus minutus, and again by Edmondson in 1931 as Megametope sulcatus, both of which are junior subjective (heterotypic) synonyms.[1] The affinites of Rathbun's species with other genera have also been unclear;[1] its apparent affinities with the genus Medaeus are superficial.[1] When Danièle Guinot split the genus Cycloxanthops in 1968, creating the new genus Neoxanthops, C. cavatus was not explicitly placed in either genus.[1] A new genus, Jacforus, was erected in 2003, commemorating Jacques Forest,[1] and containing only J. cavatus.[2]
