Two brachyuran crabs collected at Socotra Island (Republic of Yemen) in the
northwestern part of the Indian Ocean turned out to be conspecific with Sp
haerocarcinus bedoti Zehntner, 1894. so far only known from a single female
collected at Amboina, Indonesia, without any information on its ecology. B
ased on the new material and especially the availability of a male for comp
arison of the morphology of the copulatory appendages (gonopods), Sphaeroca
rcinus Zehntner, 1894, is synonymised with Caphyra Guerin, 1832. The extrem
ely convex and globose carapace shape of the type specimen from Amboina tur
ned out to be atypical and possibly caused by parasitic infection. Ecologic
ally, C. bedori, like most species of the genus Caphyra, lives epibiontic o
n soft corals (Octocurallia: Alcyonaria).
