Abstract
Eriophyoid mites are the smallest arthropods in Acari, with an average body length of 200 ïm. Eriophyoid mites also have highly reduced setae and have only two pairs of legs. There are more than 4,000 reported species of eriophyoid mites worldwide, classified in the superfamily Eriophyoidea. We collected 44 species of eriophyoid mites that represent all of the representative families, major subfamilies and tribes of Eriophyoidea and inferred the high-level phylogeny of eriophyoid mites with sequences of two mitochondrial genes (COI and 16S), two nuclear genes (18S and 28S rRNA) and 22 morphological characters. We reconstructed phylogenetic trees with concatenated datasets using maximum likelihood (ML) and Bayesian methods. ML and Bayesian trees have similar topologies. We try to use phylogeny to investigate the key sensu Amrine et al. The new phylogeny derived from such evidences departs from the current classification system. Monophylies of two subfamilies and one tribe of eriophyoid mites, Diptilomiopinae, Rhyncaphytoptinae and Anthocoptini, were recovered in our phylogenetic analysis with strong support. The monophylies of the three families, Phytoptidae, Eriophyidae and Diptilomiopidae, however, were not recovered. We traced some morphological characters at family, subfamily, tribe or genus level on BI-tree. Our phylogenetic analysis indicate that anterior seta is a plesiomorphy to the family Phytoptidae, and gnathosoma that abruptly curves and bends down near base is an apomorphy to the Diptilomiopdae. From the ML and BI analysis, both homomorphism and host plant association contribute the phylogeny of eriophyoid mites.
