| Abstract: | Kanouh, M., Tixier, M.‐S., Okassa, M. & Kreiter, S. (2010). Phylogenetic and biogeographic analysis of the genus Phytoseiulus (Acari: Phytoseiidae) —Zoologica Scripta, 39, 450–461. The taxonomy of the genus Phytoseiulus (sub‐family Amblyseiinae), has a tumultuous and confused history. This genus currently contains four species, but in previous revisions it contained five, sometimes grouped in two genera. There are no thorough phylogenetic analyses available for the group, analyses against which taxonomic and evolutionary hypotheses could be tested. The present study aims to apply morphological and molecular data to determine phylogenetic relationships among the four species presently included in this genus plus Afroseiulus robertsi, which was previously included in this genus. The new analyses show that the species of the genus Phytoseiulus do not constitute a monophyletic group. A delineation between (i) P. macropilis, P. persimilis, P. fragariae and (ii) P. longipes and A. robertsi is observed. Biogeographic data sets showed that the Neotropical and Afrotropical regions contain the highest diversity of species of Phytoseiulus and of their host plants. Consequently, the western part of Gondwana is hypothesized to be the probable centre of origin for this taxon. |
