[The systematic position of mites of the genus Larinyssus Strandtmann (Gamasoidea, Rhinonyssidae), parasitizing gulls].
A study was carried out of the variability of mited colledted from 6 species of birds as follows: Larus argentatus Pontopp., L. minutus Pall., Gelochelidon nilotica Gm., Chlidonias leucoptera (Temm.), Ch. nigra (L.) and Sterna hirundo L. Structural peculiarities characteristic of the parasites of the above species have been revealed. The mites from St. hirundo were isolated into a distinct species, Larinyssus substerna sp. n., which is most close to L. sterna Fain, 1972. The new species differs from L. sterna in a smaller size of gnathosoma and chelicerae, lesser number of hypostomal setae and the presence of pigidial shields.
