TWO NEW SPECIES OF THE FEATHER MITE GENUS TROUESSARTIA (ACARIFORMES: TROUESSARTIIDAE) FROM ROBINS AND CHATS (PASSERIFORMES: MUSCICAPIDAE) IN THE RUSSIAN FAR EAST

Abstract

Two new species of the feather mite genus Trouessartia (Analgoidea: Trouessartiidae) are described from passerine birds in Primorsky Krai (Russian Far East): Trouessartia calliope sp. n. from the Siberian Rubythroat Calliope calliope (Linnaeus) and T. larvivorae sp. n. from the Rufous-tailed Robin Larvivora sibilans (Swinhoe) (Passeriformes: Muscicapidae: Saxicolinae). Both new species are close to T. swidwiensis Jablonska, 1968 associated with nightingales of the genus Luscinia (Linnaeus) (Muscicapidae) in having the prohysteronotal and lobar parts of the hysteronotal shield not separated in males and in having setae h1 situated on large ovate non-sclerotized areas and in the absence of the external copulatory tube in females.
