Two new species of the genus Oligonychus Berlese, namely O. shojaeii sp. nov. and O. hamedaniensis sp. nov., are described from plane trees, Platanus orientalis L. (Platanaceae), in Hamedan, Hamedan province, Iran. Four species are re-described based on new Iranian material: O. afrasiaticus (McGregor, 1939), O. coniferarum (McGregor, 1950), O. punicae (Hirst, 1926) and O. saccharinus Baker & Pritchard, 1960. Among them O. saccharinus is the most important pest on sugarcane farms in southern Iran. All active life stages are described for all species except O. afrasiaticus, allowing us to confirm the ontogenetic patterns of leg setae in the Tetranychini. We refine the definition of the ununguis species group and discuss taxonomic problems relating to the members of this species group, and also regarding the identification of O. sacchari (McGregor, 1942) and O. saccharinus.
Four new species of the genus Cenopalpus Pritchard and Baker are described from Iran, namely: C. rubusi sp. nov.,collected from salmonberry bushes, Rubus persicae L. (Rosaceae), Sanandaj, Kurdistan province; C. prunusi sp. nov.from plum trees, Prunus domestica L. (Rosaceae), Hamedan, Hamedan province; C. khosrowshahii sp. nov. from Sophoraalopecuroides L. (Fabaceae), Hamedan, Hamedan province; and C. quercusi sp. nov. from oak trees, Quercuscastaneifolia C.A. Mey. (Fagaceae), Robat Namaki, Lorestan province. Six species are re-described: C. saryabiensisAkbar and Chaudhri, 1985, C. lanceolatisetae (Attiah, 1956), C. irani Dosse, 1971, C. abaii Khosrowshahi and Arbabi,1997, C. bakeri Düzgünes, 1967 and C. crataegi Dosse, 1971. Of these species, C. irani reaches high population density and is widespread. A key to all known Iranian species of the genus is provided.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
