Sense Organs on Palps and Fore Tarsi of Gamasid Mites (Parasitiformes, Rhinonyssidae), Parasites of the Nasal Cavity of the Great Tit, the Rock Dove, and the Eurasian Coot

摘要

Palpal and tarsal sensilla of mites parasitizing in the nasal cavity of the Great Tit Pams major (Ptilo-nyssus sairae, Ptilonyssus pari), the Rock Dove Columba livia (Mesonyssus melloi), and the Eurasian Coot Fulica atra (Rallinyssus caudistigmus), were examined under a scanning electron microscope. Differences in the topography of the tarsal organ reflect phylogenetic relations of species and genera, whereas differences in the structure of palpal receptors reflect the ecological peculiarities of parasitism.
