INTRODUCTION All found mites were preserved in 70% ethanol. Then asal mites of the family Rhinonyssidac are mites were cleared in 75% lactic acid for 2-4 hr, put Npermanent parasites living in the respiratory tract again in 70% ethanol for 2-3 min and finally mounted of birds. Most species of these slow-moving mites in slides with the 1 loyer medium. The description of live in nasal cavities, and some species can occupy the the new species follows the modern format used for lungs, tracheae and air sacs (Porter and Strandtmann rhinonyssid mites (Knee et al, 2006). All measurements 1952, Krantz and Walter 2009). Rhinonyssid mites arc are in micrometers. The type material is deposited in mainly transmitted via the oral route, when infested birds the Zoological Institute of the Russian Academy of regurgitate food to their nestlings or during courtship Sciences (Saint Petersburg, Russia). behavior. These mites arc viviparous, produce larvae in The following designations were adapted from which the nymphs arc already developed (Brcgctova, Fain and llyland (1962): LB, length of body includ 1956).

The genus Ptilonyssus Bcrlcse and Trouessart in RESULTS 1889 is the most diversiform and species-rich genus Family Rhinonyssidae Trouessart, 1895 within the family Rhinonyssidac and currently includes over 130 species (Pence 1975). Representatives of this Genus Ptilonyssus Ber lese and Trouessart in 1889 genus mainly parasitize birds from the order Passeri- This genus includes more than 130 species (Pence formes; several species of this genus were recorded and 1975) and there several different concepts regarding hosts from the order Caprimulgiformes, balconiformcs, its taxonomic borders, Some authors accepting genus Apidiformes (Knee et al. 2010).
