First Detection of in Namibian Bird Ectoparasites (Acariformes: Syringophilidae) with a Description of New Quill Mite Species.

is a common intracellular bacterial genus that infects numerous arthropods and filarial nematodes. In arthropods, it typically acts as a reproductive parasite, leading to various phenotypic effects such as cytoplasmic incompatibility, parthenogenesis, feminization, or male-killing. Quill mites (Acariformes: Syringophilidae) are a group of bird parasites that have recently attracted increasing interest due to the detection of unique phylogenetic lineages of endosymbiotic bacteria and potentially pathogenic taxa.

Evaluation of Genetic Diversity in Quill Mites of the Genus Kethley, 1970 (Prostigmata: Syringophilidae) with Six New-to-Science Species.

Quill mites (Acariformes: Syringophilidae) are poorly explored bird parasites. Kethley, 1970, is the most specious and widespread genus in this family. It is believed to contain mono-, steno- and poly-xenous parasites and thus seems to be an exemplary for studies on biodiversity and host associations.

A new quill mite Torotrogla emberizae sp. nov. (Acariformes: Syringophilidae) from the Chestnut-eared Bunting (Passeriformes: Emberizidae) in Japan (morphology and DNA barcode data).

A new quill mite Torotrogla emberizae sp. nov. (Acariformes: Syringophilidae) parasitizing the Chestnut-eared Bunting Emberiza fucata Pallas, 1776 (Passeriformes: Emberizidae) in Japan is described based on the external morphology and DNA barcode data (mitochondrial cytochrome c oxidase subunit I sequences, COI).

Two new picobiin mite species (Acari: Cheyletoidea: Syringophilidae) parasitizing passerine birds in Guyana.

Two new picobiin mite species (Cheyletoidea: Syringophilidae) are described from passeriform birds in Guyana, Rafapicobia automoli sp. nov. parasitizing two furnariid species Automolus ochrolaemus (Tschudi) (type host) and Automolus rufipileatus (Pelzeln) (Passeriformes: Furnariidae) and Neopicobia herbicolae sp.

A new quill mite species Neopicobia hepburni sp. nov. (Cheyletoidea: Syringophilidae) parasitizing picid birds (Piciformes: Picidae) in Peru.

A new quill mite species Neopicobia hepburni sp. nov. is described from the Ecuadorian Piculet Picumnus sclateri Taczanowski (type host) and the Olivaceous Piculet Picumnus olivaceus Lafresnaye (Piciformes: Picidae) from Peru.

Two new quill mite species (Prostigmata: Syringophilidae) parasitizing Australian birds.

Two new quill mite species (Prostigmata: Cheyletoidea: Syringophilidae), Syringophilopsis philemonis sp. nov. from Philemon citreogularis (Gould) (Passeriformes: Meliphagidae) and Megasyringophilus cacatua sp.

On the arboreal acarofauna of Hungary: some new and rare species of prostigmatic mites (Acari: Prostigmata: Tydeidae, Iolinidae and Stigmaeidae).

Eleven arboreal prostigmatic mites from the families Tydeidae, Iolinidae and Stigmaeidae (Prostigmata) are recorded from Hungary. Among them, 8 species are new for science: Tydeus narolicatus Kazmierski and Ripka sp. nov.

A new quill mite species Syringophilopsis davidi sp. nov. (Prostigmata, Syringophilidae) parasitizing Greater Short-toed Lark Calandrella brachydactyla (Leisler) (Passeriformes, Alaudidae) in Egypt is described.
