Roztoči z čeledi Harpirhynchidae žijí parazitickým způsobem na těle u řady druhů ptáků. Zástupci rodu Harpirhynchus tvoří makroskopicky zřetelné kožní cysty lokalizované pod křídly. H. nidulans tvoří cysty u dlasků tlustozobých a H. dusbabeki u sýkořic vousatých. Identifikováno bylo několik dalších druhů a rodů u různých skupin ptáků a protože jsou tito parazité hostitelsky specifičtí, lze očekávat nálezy dalších dosud neznámých druhů. and Mites from the family Harpirhynchidae are permanent highly specialized skin-dwelling bird parasites. The representatives of the genus Harpirhynchus create macroscopic voluminous cutaneous cysts located mainly at the base of the wings. In various bird species and genera, some new species from the family studied have been identified. Because these parasites are host-specific, more hitherto unknown species are expected to be found.
Six mite species of the family Myobiidae, Radfordia (Auslromyobia) persica sp. п., Radfordia (Austromyobia) merioni Bochkov, Dubinina et Chirov, 1990, Radfordia (Radfordia) acomys Fain ct Lukoschus, 1977, Radfordia (Radfordia) affinis (Poppe, 1896), Radfordia (Graphiurobia) dyromys Fain et Lukoschus, 1973, and Myobia (Myobia) murismusculi (Schrank, 1781) were found in Iran on the rodents Gerbillus cheesmani Thomas, Meriones libycus Lichtenstein, Acomys cahirinus (Desmarest), Mus musculus L., Dryomys nitedula (Pallas), and Mus musculus, respectively. R. (A.) persica is described as a new species from the female, male and tritonymph. The other five myobiid species arc new to Iran.
Two new species of the syringophilid mites (Acari: Syringophilidae) are described from quills of passeriform birds. Syringophilopsis faini sp. n. is described from Sylvia curruca (L.) (Sylviidae) and Syringophiloidus carpodaci sp. n. is described from Carpodacus erythrinus (Pall.) (Fringillidae). Characters are detailed that differentiate Syringophilopsis faini from three species of a new "turdus" group, and Syringophiloidus carpodaci from S. minor.
