A New Species of the Genus Larinyssus Strandtmann (Mesostigmata: Rhinonyssidae) from the Common Tern Sterna hirundo (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.
