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

Abstract

A new nasal mite species, Larinyssus iohanssenae n. sp. (Mesostigmata: Rhinonyssidae), is described on the basis of the material obtained from the Common Tern Sterna hirundo Linnaeus (Charadriiformes: Sternidae) collected in Leningrad province, Russia. Larinyssus iohanssenae n. sp. is distinguished from closely related species Larinyssus substerna Butenko, 1975 by the absence of dorsal shields or shieldlets on idiosoma, the absence of sternal shield, and the presence of the narrow genital shield which is approximately four times longer than its width.

Arthropod parasites of Antarctic and Subantarctic birds and pinnipeds: A review of host-parasite associations

“…Larinyssus orbicularis has not yet been recorded in the Antarctic region, but it is known to infest kelp gulls in South Africa and South America ( Zumpt and Till, 1955 ; González-Acuña et al, 2011 ). Considering that rhinonyssid mites can go unnoticed for decades even when they are abundant in extensively studied hosts ( González-Acuña et al, 2011 ; Dimov, 2013 ; Vanstreels et al, 2019 ), it seems probable that the occurrence of these parasites has been underestimated in the Antarctic region.…”
