Technical Abstract: Some mite species of the genus Brevipalpus are considered pests of economic importance for several agricultural crops such as citrus and coffee. They are associated with the transmission of viruses [e.g.:citrus leprosis virus (CiLV), coffee ringspot virus (CoRSV)]. Recent studies indicate that the most important species implicated in transmission of CiLV and CoRSV, Brevipalpus phoenicis, is in fact a complex of cryptic species. We have identified several distinct morphospecies that have previously been identified as B. phoenicis. The objective of this research was to study the morphology of different populations of B. phoeTticis of group species B, from different localities in the State of Sao Paulo. Samples of leaves and branches were ollected from citrus and coffee plants, in several localities in the State of Sao Paulo. Brevipalpus females from the samples were isolated in leaf disc arenas to produce lines derived from a single female. Permanent slides of females, deutonymphs, protonymphs and larvae of each line were mounted for morphometricanalysis.Byexamining18morphological characteristics [length of propodosomal and histerosomal setae and ventral setae (3a, ag, gl e g2), length and width of idiosoma] of mites, we observed significant differences among the lines. Thirteen morphospecies of B. phoenicis belonging to the group species B were detected in Brazil. Performing the cluster analyzes (Morisita index), it was possible to separate them into 3 major groups, one of coffee and two of citrus. Future studies of biology, sensibility to chemicals, virus transmission and molecular analysis will be performed.
