Lachesilla rossica is a rare psocopteran species described from southern Russia.[1] The species can be found in Ukraine as well.[2] It was discovered many years later in the valley of the Allondon river, near Geneva, Switzerland.[3] In the latter habitat, it occurs together with Lachesilla bernardi, a congeneric species that is visually very similar to it: the examination of genitalia with a microscope is the only way to differentiate the two species. It was reported recently from Albania too. [4]
