Phylogenetic and biogeographic analysis of the genus Caribeacarus (Acari : Opilioacarida), with description of a new South American species

Abstract

The mite order Opilioacarida is widely distributed in the tropical and sub-tropical zones of the world, where it is rare and poorly known. On the American continent only two genera, 14 species and one subspecies are known. This work aimed to describe a new species of Caribeacarus from the state of Pará, in the eastern part of the Brazilian Amazon. A phylogenetic analysis of the species in this genus is also presented, and interpreted along with the historical biogeography of this genus in Central and South America. A key to the species of Caribeacarus is provided.
