Integrated taxonomy supports the identification of some species of Phytoseiidae (Acari: Mesostigmata) from Georgia
Acarologia 61 (4), 824-844
Abstract: The present study reports results of a survey carried out mostly on Citrus sp. and Rubus sp. in Georgia. Morphological and molecular (12S rRNA, COI and CytB mtDNA markers) data were analysed in a framework of integrative taxonomy. Eleven species were identified and among them seven are new for the Georgian fauna. Euseius stipulatus and Phytoseius finitimus were the most abundant species during this survey. We assume that Amblyseius eharai, only reported from eastern Asia, was most probably introduced. Neoseiulus californicus, retrieved from uncultivated vegetation, was almost certainly originating from commercial strains. DNA sequences comparisons disclosed phylogenetic closeness between Amblyseius andersoni and Transeius wainsteini, despite these species (i) being morphologically well differentiated and (ii) classified in different genera, thereby questioning the reliability of the genus Transeius. General morphological characters, including measurements, are provided for species for which diagnoses were doubtful.
