Four new species, Rhinophytoptus domestica, Paraphytoptus rosae, Diptacus caesius and Eriophyes padi are described from Germany and Austria. Rhinophytoptus domestica n. sp. prefers the undersurface of the leaves on P. domestica as a vagrant, has protogyne and deutogyne females like R. avium n. sp., differs from this species by the different nymphal stage, different shield design, female genital coverflap, tarsal empodium, structure on ventral annuli of protogyne female and other morphological characteristics. Paraphytoptus rosae n. sp., from R. canina, lives on the upper surface of leaves in the stipule region and causes moderate proliferation through cell-division. Hitherto, no species of Paraphytoptus was described from R. canina. Eriophyes padi n. sp. prefers the under surface of the leaves of P. padus as a vagrant. They differ from hitherto known eriophyids of bird cherry in morphological characteristics and specificity of reaction upon their host plant. Diptacus caesius, a new species from the dewberry, R. caesius, is free-living on the underside of the leaves, when it has not been observed to cause any damage.
