A review of the genus Pseudolaelaps Berlese, 1916 (Acari: Mesostigmata, Pseudolaelapidae), with descriptions of eleven new species from Europe

The study presents a review of the genus Pseudolaelaps Berlese, 1916 (Acari: Mesostigmata, Pseudolaelapidae), based on over 200 specimens collected from Bulgaria, Croatia, France, Greece, Italy, Romania, Serbia, Slovakia and Ukraine, including the type specimens of three species (P. doderoi, P. gamaselloides, and P. paulseni) deposited in the Berlese Acaroteca, Florence. The European fauna is shown to include 14 species, 11 of which are described as new: P. barbatus sp. nov. (Romania, Serbia), P. brevipilis sp. nov. (Bulgaria), P. jozefi sp. nov. (Greece), P. lepidus sp. nov. (Italy), P. mirandus sp. nov. (Bulgaria), P. pallidus sp. nov. (Italy), P. propinquus sp. nov. (Italy), P. regularis sp. nov. (Bulgaria), P. rotundus sp. nov. (Romania, Slovakia, Ukraine), P. scaber sp. nov. (France, Italy), and P. stellifer sp. nov. (Bulgaria, Romania, Slovakia). One of the Berlese species, P. gamaselloides Berlese, 1920, is redescribed and newly reported from Croatia and Slovakia. A key for identification of Pseudolaelaps species is provided.
