During investigations of oribatid mites from Shiraz, Fars Province in southern Iran, a new species of Epilohmannia (Acari: Oribatida: Epilohmanniidae) was found from soils under oak and willow trees. Epilohmannia rotundistriata sp. nov. is distinguishable from other species by the broadly rounded rostrum with longitudinal striations; bothridial seta with long, finely barbed stalk and strongly swollen, fusiform head bearing many distinct barbs; anterior margin of notogaster concave; notogastral setae c₁ and c₂ situated transversely nearly at the same level; anal and adanal setae thickened, barbed, ad₃ distinctly shorter than the other two adanal setae; all apodemes well developed; tarsi of leg IV with three thick spine-like setae (a″, s and tc′). A key for identifying known species of Epilohmannia in Iran, is provided.
