A New Metaculus Species (Acari: Eriophyoidea) on Diplotaxis tenuifolia (Brassicaceae) From Serbia: A Combined Description Using Morphology and DNA Barcode Data

摘要

A new species of eriophyoid mite, Metaculus diplotaxi n. sp. inhabiting Diplotaxis tenuifolia ( L.) DC., is described from Serbia. To investigate interspecific variability between Metaculus spp. on three different Brassicaceae host plants ( viz. D. tenuifolia, Lepidium latifolium ( L.), Isatis tinctoria ( L.)), we analyzed phenotypic variability of morphological traits and molecular sequences of the mitochondrial cytochrome oxidase subunit I ( MT- CO1). Discriminant analysis identified seven traits that significantly differentiate three Metaculus spp: M. lepidifolii, M. rapistri, and M. diplotaxi n. sp. Analysis of MT- CO1 sequences supported the results obtained from the analysis of morphometric features.
