Abstract
Four species of Sunaristes (Canuellidae) are known to live in association with hermit crabs and exhibit a degree of host specificity. Although hermit crabs are common in many parts of the world, Sunaristes is notably absent from waters of the New World. The phylogeny of Sunaristes is here examined through a cladistic analysis. The reconstructed phologeny indicates that S. inaequalis and S. japonicus form a sister group, and its closest relative is S. tranteri. The sister taxon of this 3-species clade is S. paquri. It is assumed that Sunaristes evolved in the Paleocene on the north shore of the Tethys seaway. The constructed cladogram forms the basis for the analysis of vicariant events that led to the speciation and development of the present pattern of distribution of Sunaristes.
