Syringophilid mites (Acari: Syringophilidae) associated with the rails (Aves: Rallidae) and a key to the species of the genus Rafapicobia Skoracki, 2011.

The fauna of quill mites of the family Syringophilidae Lavoipierre, 1953 (Acari: Prostigmata Cheyletoidea) parasitising birds of the family Rallidae Vigors (Gruiformes) is updated. A new species, Rafapicobia melzeri n. sp. (subfamily Picobiinae), is described from four host species: Rallus aquaticus Linnaeus (type-host) from Germany, Pardirallus sanguinolentus (Swainson) from Chile, Porzana porzana (Linnaeus) from France and P. parva (Scopoli) from Kirghizia. The new species is most similar to R. lepidocolaptesi Skoracki & Solarczyk, 2012 but differs in the absence of agenital plates and the length ratios of setae ag2:g1 and vi:ve:si in females and in the punctate ornament on the hysteronotal and the pygidial shields in males. A key to the species of the genus Rafapicobia is proposed. This is the first record of a representative of the subfamily Picobiinae on gruiform birds. Additionally, new rallid hosts are reported for Charadriphilus ralli Skoracki & Bochkov, 2010 (subfamily Syringophilinae): Gallinula melanops (Vieillot) from Chile, Laterallus melanophaius (Vieillot) from Paraguay, and P. parva (Scopoli) from Kirghizia.

Enigmatic host-mite relationships: Unraveling the distribution of quill mites on Birds-of-Paradise.

Mites of the family Syringophilidae (Acariformes: Prostigmata: Cheyletoidea) are permanent and obligatory parasites of birds. This study presents an analysis of mite material collected from 22 avian species belonging to the family Paradisaeidae (Passeriformes), revealing the presence of four mite species belonging to four genera: Syringophiloidus attenboroughi n. sp., Peristerophila regiusi n. comb., Picobia frankei, and Gunabopicobia garylarsoni. In the present work, the genus Neoperisterophila is synonymized with the genus Peristerophila. While the genera Syringophiloidus and Picobia were expectedly found on paradisaeid birds, given their prevalence in passerines, the presence of Peristerophila and Gunabopicobia was intriguing, suggesting potential host-switching events. The specificity of these mites varies, with some showing occurrence on hosts of closely related genera and others infesting phylogenetically distant hosts. Notably, the distribution of specific mite species on the Birds-of-Paradise appears to be influenced by both long coevolutionary histories and incidental contacts between often unrelated or intergeneric hybrid species of paradisaeid birds. Furthermore, our research of 104 specimens from 22 Birds-of-Paradise species shows generally low infestation rates across the studied species, suggesting a nuanced interaction between these mites and their avian hosts. Additionally, our network analysis provides a deeper understanding of these host-parasite interactions, revealing a high level of specialization and complexity in these ecological relationships.

A new genus of quill mites of the family Syringophilidae (Acari: Cheyletoidea) associated with mousebirds (Aves: Coliiformes).

A new monotypic genus Colisyringophilus n. g. is established for C. tanzanicus n. sp., quill mites parasitising two mouse bird species from Tanzania, Colius striatus Gmelin and Urocolius macrourus (Linnaeus). This new genus is closely related to Neoaulobia Fain, Bochkov & Mironov, 2000, but differs from it by the following features: the stylophore is rounded posteriorly, the propodonotal shield is reduced to triangular sclerite bearing bases of setae vi and ve, the hysteronotal shield is absent, legs I are longer than legs II, and apodemes I are distinctly elongated. This is the first record of syringophilid mites from hosts of the order Coliiformes.

Three new quill mite species of the genus Neoaulonastus Skoracki (Acari: Syringophilidae) parasitizing passerines in Tanzania.

Three new species of the genus Neoaulonastus Skoracki, 2004 found inside the quills of the body feathers are described: N. tanzanicus sp.nov. from Euplectes axillaris (Smith) (Passeriformes: Ploceidae), N. quelea sp.nov. from Quelea quelea Linnaeus (Ploceidae) and N. granatina sp. nov. from Granatina ianthinogaster Reichenow (Estrildidae). All avian hosts were captured in Tanzania. Key to Neoaulonastus species is proposed.

Species Composition of Parasitic Mites of the Subfamily Picobiinae (Acariformes: Syringophilidae) Associated with African Barbets (Piciformes: Lybiidae).

In this study, we conducted a parasitological investigation of the quill mite fauna of the subfamily Picobiinae (Acariformes: Prostigmata: Syringophilidae) associated with African barbets (Aves: Piciformes: Lybiidae). We examined twenty-seven host species, representing 57% of the forty-seven known host species in the family Lybiidae, belonging to seven genera (70% of the ten genera in the family). Our research revealed that ten host species were infested by three species of picobiine mites belonging to the genus Tanopicobia: (1) Tanopicobia hallae Sikora and Skoracki, sp. n., from three species of the genus Lybius and two species of the genus Tricholaema, (2) Tanopicobia stactolaema Sikora and Skoracki, sp. n., from two species of the genus Stactolaema, and (3) Tanopicobia trachyphoni Skoracki et al., 2020, collected from three host species of the genus Trachyphonus. Our findings demonstrate that birds belonging to the family Lybiidae have a specific parasite fauna consisting exclusively of mites of the genus Tanopicobia; this mite genus is apparently restricted to African barbets.

First Records of Picobiine Mites Associated with Birds-of-Paradise: Can Interspecific Sexual Behaviour of Hosts Play a Role in the Distribution of Quill Mite Parasites?

While birds-of-paradise (Passeriformes: Paradisaeidae) are a well-known group of birds, our understanding of their parasites is still limited. This study reports on parasitic quill mites of the subfamily Picobiinae (Acariformes: Syringophilidae), which have never before been recorded on this group of birds. The mite specimens presented in this paper were collected from birds-of-paradise that had been captured in Papua New Guinea and Indonesia in the years 1910-1911 and are now deposited in the Bavarian State Collection of Zoology, Munich, Germany. Two syringophilid species are described as new to science: (i) Picobia frankei sp. n. from the magnificent riflebird Lophorina magnifica, the glossy-mantled manucode Manucodia ater, and the crinkle-collared manucode Manucodia chalybatus, and (ii) Gunabopicobia garylarsoni sp. n. from the twelve-wired bird-of-paradise Seleucidis melanoleucus and the lesser bird-of-paradise Paradisaea minor. We hypothesise that the presence of both picobiine species on phylogenetically unrelated paradisaeids may be caused by the sexual behaviour of these birds, where interspecific copulations may play a role in the switching of parasites between non-closely related host species.

Three new quill mite species of the genus Neoaulonastus Skoracki (Acari: Syringophilidae) parasitizing passerines in Tanzania.

Three new species of the genus Neoaulonastus Skoracki, 2004 found inside the quills of the body feathers are described: N. tanzanicus sp. nov. from Euplectes axillaris (Smith) (Passeriformes: Ploceidae), N. quelea sp. nov. from Quelea quelea Linnaeus (Ploceidae) and N. granatina sp. nov. from Granatina ianthinogaster Reichenow (Estrildidae). All avian hosts were captured in Tanzania. Key to Neoaulonastus species is proposed.

Peristerophila falcophila sp. nov., a new species and first record of quill mites (Acariformes: Syringophilidae) parasitizing birds of the order Falconiformes.

Parasitic Quill Mites of the Family Syringophilidae (Acariformes: Prostigmata) Associated With Sub-Saharan Sunbirds (Passeriformes: Nectariniidae): Species Composition and Host-Parasite Relationships.

We investigated the quill mite fauna of the family Syringophilidae (Acariformes: Prostigmata) associated with Sunbirds (Passeriformes: Nectariniidae) in the Sub-Saharan region. Six hundred eleven host individuals belonging to 52 species were examined. Syringophilid parasitization prevalence (44 hosts of 15 species) ranged from 1.4 to 75% in particular host species. In the collected material, we have found seven quill mite species and among them four are new for science: 1) Aulobia afroanthreptes Skoracki & Zmudzinski sp. nov. from Anthreptes neglectus Neumann, 1922 and Anthreptes longuemarei (Lesson, 1831), both from Tanzania; 2) Syringophiloidus nectariniae Skoracki & Zmudzinski sp. nov. from Hedydipna collaris (Vieillot, 1819) from Tanzania; 3) Aulonastus nectariniphilus Skoracki & Zmudzinski sp. nov. from Anthreptes reichenowi Gunning, 1909 from Tanzania and Nectarinia tacazze (Stanley, 1814) from Ethiopia; and 4) Picobia hedydipna Skoracki & Zmudzinski sp. nov. from Hedydipna collaris from Kenya. Representatives of the genera Aulonastus Kethley, 1970 and Syringophiloidus Kethley, 1970 are recorded on Sunbirds for the first time. The following new host species are given: Cinnyris mariquensis Smith, 1836, C. shelleyi Alexander, 1899 and C. regius Reichenov, 1893, all from Tanzania for Aulobia nectariniae Skoracki & Glowska, 2008; A. neglectus and A. longuemarei, both from Tanzania for Neoaulonastus cinnyris Klimovicova et al., 2014; Cyanomitra verreauxii (Smith, 1832) from Tanzania and Cinnyris chalybeus (Linnaeus, 1766) from South Africa for Picobia oritis Skoracki et al., 2009. Additionally, host-parasite relationships are discussed.
