A new species of the genus Euseius Wainstein (Acari: Phytoseiidae) from Republic of Congo

Several individuals belonging to the genus Euseius, have been collected from three host plants (cassava, okra, and chilli) in the Republic of the Congo. Previous molecular and morphological analysis (integrative approach) have shown that 1) morphological differences existed between the Euseius sp. and both E. neodossei and E. fustis, and 2) both mitochondrial DNA fragments considered (i.e., 12S rRNA and ITSS) showed a clear delineation between Euseius sp. and E. fustis. It was not possible to compare these species with E. neodossei (a morphologically close species) owing to the lack of DNA sequences in GenBank for this species. The purpose of this study was to describe a news species Euseius congolensis sp. nov from Republic of the Congo.
