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

Quill mites (Acariformes: Syringophilidae) are poorly explored bird parasites. Syringophiloidus 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. In this work, we applied the DNA barcode marker (mitochondrial cytochrome c oxidase subunit I gene fragment, COI) to analyze the species composition and host specificity of representatives of fifteen Syringophiloidus populations parasitizing fifteen bird species. The neighbor joining analyses distinguished thirteen monophyletic lineages, almost completely corresponding to seven previously known species recognized based on morphological features, and six new-to-science species. The only exception is S. amazilia Skoracki, 2017, which is most likely conspecific with Syringophiloidus stawarczyki Skoracki, 2004. The intraspecific distances of all species were not higher than 0.9%, whilst the interspecific diversity ranged from 5.9% to 19.2% and 6.3-22.4%, inferred as the distances p and K2P, respectively. Although all putative species (except S. amazilia) are highly supported, the relationships between them have not been fully resolved and only faintly indicate that both host phylogeny and distributions influence the phylogenetic structure of quill mite taxa.

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). Females of T. emberizae sp. nov. differ from T. volgini Skoracki and Mironov, 2013 by having the short, wide and blunt-ended hypostomal protuberances (vs long, thin and sharp-ended), setae h1 ca. twice shorter than f1 (vs h1 longer than f1), the fan-like setae p' and p" of legs III-IV provided with ca. 10 tines (vs 7-8 tines) and lengths of setae vi 70-105 (vs 55-65), ve 105-135 (vs 85-90) and h1 55-60 (vs 95-120).

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. nov. from Emberizoides herbicola (Vieillot) (Thraupidae). Additionally, Picumnus exilis (Lichtenstein) (Piciformes: Picidae) is recorded as a new host species for Neopicobia hepburni Glowska et Laniecka, 2014.

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. Females of N. hepburni are distinguishable from most similar species N. ea Skoracki et Unsoeld by the propodonotal shield divided into 3 sclerites, the pygidial shield with a vertical furrow and wing-like appendages, the presence of the genital lobes, setae f2 2.7 times longer than f1 and length ratio of ag1:ag2:ag3 equals 2:1:2. In females of N. ea, the propodonotal shield is entire, the pygidial shield is oval, without vertical furrow and appendages, the genital lobes are absent, setae f2 are 4.5-5.5 times longer than f1 and length ratios of ag1:ag2:ag3 are 2.2-2.7:1:3-3.2.

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., T. martae Kazmierski sp. nov., T clavimaculatus Kazmierski sp. nov., Lorryia hungarica Laniecka and Ripka sp. nov., L. sanctikingai Ripka and Laniecka sp. nov., L. bathorii Ripka and Kazmierski sp. nov., Neopronematus solani Laniecka and Kazmierski sp. nov., and Mediolata ronaldi Laniecka sp. nov. Neopronematus lundqvisti Sadeghi et al., 2012 is a new species for fauna of Hungary.

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. nov. from Cacatua galerita (Latham) (Psittaciformes: Psittacidae) are described from Australia.

Syringophilopsis davidi sp. nov. (Prostigmata, Syringophilidae) a new quill mite species parasitizing Calandrella brachydactyla (Passeriformes, Alaudidae) in Egypt.

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. This new species is distinguishable from S. tyranni Bochkov and Galloway by 10-13 chambers of the peritremal lateral branches, setae se located slightly anterior to c1, and by setae ag2 about twice longer than the genital setae. This is the first record of this genus from the hosts of the family Alaudidae and in the Arab Republic of Egypt.
