| abstract | The new genus and species Apediculaster carpelimus Rahiminejad and Hajiqanbar gen. nov., sp. nov. (Acari: Prostigmata: Pygmephoridae) are described and illustrated from Oak forests in northern Iran, based on phoretic females associated with Carpelimus (Paratrogophloeus) rivularis (Motschulsky, 1860) (Coleoptera: Staphylinidae: Oxytelinae). The new genus is close to the genera Pediculaster Vitzthum, 1931, Pediculitopsis Mahunka, 1970 and Brasilopsis Mahunka, 1975 but can be distinguished by one pair of setae h on tergite H, two pairs of simple setae (v1, sc2) on prodorsum and one pair of pseudanal setae. |
