New records of feather mites (Sarcoptiformes: Proctophyllodidae) on tanagers (Passeriformes: Thraupidae) from Brazil

Herein, three feather mite species (Analgoidea: Proctophyllodidae) are reported from tanagers (Passeriformes: Thraupidae) in Brazil: Proctophyllodes thraupis Atyeo & Braasch, 1966 on Thraupis ornata (Sparrman, 1789), Thraupis palmarum (Wied, 1821), and Stilpnia peruviana (Desmarest, 1806); Amerodectes thraupicola (Černý, 1974) and Amerodectes bilineatus (Berla, 1958) on T. ornata. Proctophyllodes thraupis is herein reported for the first time on the hosts mentioned above. Amerodectes thraupicola is reported in synoxenism with A. bilineatus on the same bird specimen of T. ornata, a new host for both mites. Despite being described from a Cardinalidae (Passeriformes) host, this latter mite species was subsequently recovered only from tanagers, which reinforces the suggestion that non-thraupid hosts might be accidental records.

Feather mites (Acariformes, Astigmata) from marine birds of the Barton Peninsula (King George Island, Antarctica), with descriptions of two new species

We report on the first investigation of feather mites associated with birds living on the Barton Peninsula (King George Island, Antarctica). We found seven feather mite species of the superfamily Analgoidea from four host species. Two new species are described from two charadriiform hosts: Alloptes (Sternalloptes) antarcticussp. nov. (Alloptidae) from Stercorarius maccormicki Saunders (Stercorariidae), and Ingrassia chionissp. nov. (Xolalgidae) from Chionis albus (Gmelin) (Chionidae). Additionally, we provide partial sequences of the mitochondrial cytochrome c oxidase subunit I (COI), which was utilized as a DNA barcode, for all seven feather mite species.

The identity of Plesialges mimus Trouessart, 1919 and taxonomic notes on the feather mite genus Hemialges Trouessart, 1895 (Acariformes: Analgidae)

The feather mite Plesialges mimus Trouessart, 1919, briefly described from the White-browed Babbler Pomatostomus superciliosus (Vigors & Horsfield) (Passeriformes: Pomatostomidae), is the only species of the genus Plesialges Trouessart, 1919. In this work, I redescribe this mite species based on the type specimens, transfer it into the genus Hemialges Trouessart, 1895, and provide it with the valid name Hemialges mimus (Trouessart, 1919) comb. n. The genus Plesialges syn. n. is synonymized with the genus Hemialges. A new diagnosis, comments on taxonomy and an updated checklist of species are provided for the genus Hemialges. The transfer of P. mimus to the genus Hemialges created a conflict with the previously named Hemialges mimus Trouessart, 1920 from the Trumpet Manucode, Phonygammus keraudrenii (Lesson & Garnot) (Passeriformes: Paradisaeidae). Hemialges mimus (Trouessart, 1919) comb. n. is now the older homonym within this genus and H. mimus Trouessart, 1920 from the Trumpet Manucode is a junior homonym; here I provide the latter with a new name, Hemialges trouessarti nom. n.

Two new feather mites of the genus Trochilodectes Park & Atyeo (Astigmata: Proctophyllodidae) from hummingbirds in Colombia (Apodiformes: Trochilidae)

Two new species of the feather mite genus Trochilodectes Park & Atyeo (Acariformes: Proctophyllodidae) are described from hummingbirds (Apodiformes: Trochilidae) in Colombia: T. capitocaudatus sp. nov. from Ocreatus underwoodii (Lesson, 1832) and T. andinus sp. nov. from Phaethornis guy (Lesson, 1833). A key to all presently known species of the genus Trochilodectes is presented.

Two new feather mites of the genus Proctophyllodes Robin (Acari formes: Proctophyllodinae) from passerines in Brazil

Proctophyllodes Robin (Proctophyllodidae: Proctophyllodinae) is a widely distributed feather mite genus, which most species show high level of specificity to their bird hosts. We describe two new species of this genus from passerines commonly found in urban environments in Brazil: Proctophyllodes molothrus sp. nov. from the Shiny Cowbird Molothrus bonariensis (Gmelin) (Icteridae), and P. carmenmirandae sp. nov. from the Rufous-collared Sparrow Zonotrichia capensis (Statius Müller) (Passerellidae). The former is similar to P. egglestoni Spory and differs from it in having a unique shape of opisthosomal lobes in females; P. carmenmirandae is closer to P. tiaris Atyeo & Braasch and differs in having a relatively longer adeagus in males and setae h1 situated on soft tegument between hysteronotal and lobar shields in females.

Two new species of feather mites (Acarina: Psoroptidia) from the Huet's fulvetta, Alcippe hueti (Passeriformes: Leiothrichidae), in China

Two new feather mite species collected from the Huet's fulvetta, Alcippe hueti (Passeriformes, Leiothrichidae), in China are described: Proterothrix dinghushani sp. n. (Proctophyllodidae) and Trouessartia pauciseta sp. n. (Trouessartiidae). Males of P. dinghushani have a pair of lateral hysteronotal sclerites and a closed pentagonal sclerotized frame in the postero-median part of propodosoma. Females of this species have the sternum 1/4 of the total length of epimerites, and the terminal cleft exceeds half of the length of the lobar shield. Both sexes of T. pauciseta have a distinctive character, the absence of 3 pairs of hysteronotal setae (d1, d2, and e2), that clearly differs this species from all previously known species of the genus.

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

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.

THE FIRST RECORD OF PROMYIALGES PARI FAIN, 1965 (ACARIFORMES: EPIDERMOPTIDAE) FROM THE LOUSE FLY ORNITHOMYA AVICULARIA L., 1758 (DIPTERA: HIPPOBOSCIDAE) IN EUROPEAN RUSSIA

A Promyialges pari Fain, 1965 (Analgoidea: Epidermoptidae) feather mite was found on the louse fly Ornithomya avicularia L., 1758 (Diptera: Hippoboscidae), recovered from Eurasian rook, Corvus frugillegus L., 1758 (Passeriformes: Corvidae), in the south of European Russia. This is the first record of P. pari in Russia and on the aforementioned bird host.
