A New Species of the Genus <i>Larinyssus</i> Strandtmann (Mesostigmata: Rhinonyssidae) from the Common Tern <i>Sterna hirundo</i> (Charadriiformes: Sternidae) in Russia

“…Mites of the family Rhinonyssidae (Parasitiformes: Mesostigmata) are obligate haematopha� haematopha� gous parasites of birds, and they reside in the respiratory passages of their hosts (Fain, 1994;George, 1961;Knee and Proctor, 2010;Vitzthum, 1935). The majority of rhinonyssids dwell in the nasal cavities, though some species occupy the lungs, tracheal tissues and even the body cavity (Krantz, 1978;Porter and Strandtmann, 1952).…”

One new species of nasal mites of the genus Vitznyssus (Rhinonyssidae) from the Leningrad province, Russia

“…Some species occupy the lungs, tracheal tissues and body cavity of their host (Porter and Strandtmann, 1952;Krantz and Walter, 2009). They are obligate hematophagous endoparasites (Vitzthum, 1935). These mites are viviparous, and their females produce eggs in which larvae are almost completely formed (Bregetova, 1956).…”

Studies on Some Parasitic Mites from Canada and South Africa

“…It certainly seems to belong to the genus Sternostoma, which according to Vitzthum's (1935) key, is distinguished by 2 dorsal shields, the mouthparts invisible from above, and the absence of peritremes in the stigmata. Dorsal surface with two shields, the anterior one large and pentagonal, more or less pointed anteriorly; its entire area appearing finely stippled or granular under magnification, with a number of small clear alveoli forming a definite symmetrical pattern; posterior shield rod-shaped, rather wider anteriorly than posteriorly, uniformly finely granular; no anal shield.…”

“…In the first leg these have largely disappeared, the one ramus being apparently represented by the thickened boundary of the dorsal surface which is also much curved distally, the other ramus only represented by indistinct traces. Judging from the figures of various species of RHINONYS-SIDAE given by Vitzthum (1935) some of them have the claw of leg I modified, in others the claws of all four legs are similar. This modification seems to have gone even further in the species under consideration than in any of those illustrated by Vitzthum. Mouthparts.…”
