Three new species of the feather mite (Analgoidea: Proctophyllodidae: subfamily Pterodectinae) are described from passerines from Central Africa: Montesauria faini sp. nov. from the African Golden-breasted Bunting, Emberiza flaviventris Stephens, 1815 (Emberizidae), M. pallida sp. nov. from the Red-headed Weaver, Anaplectes rubriceps (Sundevall, 1850) (Ploceidae), andPedanodectes blaszaki sp. nov. from the Copper Sunbird, Cinnyris cupretis (Shaw, 1812), (Nectariniidae).
Three new species of the feather mite genus Pteroherpus Gaud, 1981 are described from the bulbuls (Passeriformes, Pycnonotidae) in Africa: Pteroherpus nicator sp. nov. from Nicator gularis Hartlaub et Finsch, 1870, P. pyrrhuri sp. nov. from Pyrrhurus scandens (Swainson, 1837), and P. trinoton sp. nov. from Phyllastrephus terrestris Swainson, 1837.
Two new feather mite species are described from ground finches of the genus Geospiza (Passeriformes, Emberizidae) collected on Galapagos Islands, Ecuador. Mesalgoides (s. str.) geospizae sp. nov. (Psoroptoididae) is found on Geospiza scandens (type host), G.fortis, G. fuliginosa, and G. conirostris; Xolalgoides palmai sp. nov. (Xolalgidae) is found on G. scandens (type host), G. fortis, and G. fuliginosa.
Three new genera of feather mites of the Protolichus generic group (Pterolichidae, Pterolichinae), restricted to parrots, are established based on re-examination of type series and some previously unidentified mite specimens deposited in the collection of E. Trouessart (Muséum National d’Histoire Naturelle, Paris, France): Loriprotolichus gen. nov. with the type species Loriprotolichus charmosynae sp. nov. from Charmosyna papou (Scopoli, 1786) and Loriprotolichus falculiger (Trouessart, 1884) comb. nov. from Glossopsitta concinna (Shaw, 1791); Calyptolichus gen. nov. with type species Calyptolichus favettei (Trouessart, 1899) comb. nov.; Nestorilichus gen. nov. with the type species Nestorilichus atyeoi sp. nov. from Nestor meridionalis (Gmelin, 1788). Several taxonomic changes were implemented in the course of re-examination of the type series. The holotype of Pterolichus (Protolichus) falculiger Trouessart, 1884 is designated. Re-examination of the full syntype series of P. (Protolichus) favettei Trouessart, 1899 representing samples from different hosts, recovered two distinct pterolichid species of the Protolichus generic group. The sample clearly corresponding to the original description (Trouessart, 1899) is fixed as the lectotype and nomenclatural type of P. (Protolichus) favettei; the second species is described as a new species Nestorilichus atyeoi. Protolichus (Mesolichus) favettei cordifora Favette et Trouessart, 1904 is synonymized with P. (Protolichus) favettei.
Two new species of the feather mite family Gabucinidae (Acari: Astigmata) are described from birds of the family Troglodytidae (Passeriformes) from Central America: Piciformobia cinnycerthiae sp. nov. from Cinnycerthia unirufa (Lafresnaye) in Ecuador, and P. henicorhinae sp. nov. from Henicorhina leucosticte (Cabanis) in Costa Rica. These are the first records of mites of the genus Piciformobia Gaud et Atyeo, 1975 from passerine hosts. A renewed diagnosis of the genus Piciformobia and key to all known species are provided.
Four new species of the feather mite subfamily Pterodectinae (Proctophyllodidae) are described from passerine birds examined in Senegal: Dolichodectes gymnoris sp. nov. from the Russet-browed Bush-sparrow Gymnoris dentata (Sundevall, 1850) (Passeridae), Montesauria plocei sp. nov. from the Village Weaver Ploceus cucullatus (Muller, 1776) (Ploceidae), M. zosteropis sp. nov. from the African Yellow White-eye Zosterops senegalensis Bonaparte, 1850 (Zosteropidae), and Proterothrix terpsiphone sp. nov. from the African Paradise-flycatcher Terpsiphone viridis (Muller, 1776) (Monarchidae). Brief notes on systematics and host associations of the pterodectine genera Dolichodectes Park et Atyeo, 1971, Montesauria Oudemans, 1905, and Proterothrix Gaud, 1968 are also given.
A new feather mites species, Proctophyllodes cetti sp. nov., is described from Cetti's warbler, Cettia cetti (Temminck, 1820) (Sylviidae) from Kazakhstan. The standard morphological description is supplemented by cytochrome subunit oxidase I sequence data (DNA barcode).
A systematic review of pterolichid feather mites of the Psittophagus generic group (Pterolichidae, Pterolichinae) is presented. New feather mite taxa are described: Psittaculobius quadriglobus gen. nov., sp. nov. from the Long-tailed Parakeet Psittacula longicauda (type host) and the Red-breasted Parakeet P. alexandri (Psittacidae, Psittacinae), Psittophagus calyptorhynchi sp. nov. from the Yellow-tailed Black Cockatoo Calyptorhynchus funereus (Cacatuidae, Calyptorhynchinae). A key to all genera and species of the Psittophagus group and taxonomic comments on formerly described species are provided, and host-parasite associations of these mites with the parrots from the Old World are briefly discussed. It is hypothesised that the Psittophagus group originated on the ancestors of Psittaciformes at the same time as other pterolichine groups specific to parrots, but in the process of coevolution with these hosts it has achieved significant success on Cacatuidae only, while on Psittacidae, the representatives of this group have been retained only on few phylogenetic lineages in the Old World.
We present a systematic revision and phylogenetic analysis of feather mites of the closely related genera Apexolichus Gaud et Atyeo, 1996 and Titanolichus Gaud et Atyeo, 1996 (Pterolichidae, Pterolichinae). New diagnoses for Apexolichus and Titanolichus and keys to all known species are provided. We redescribe all species of the genus Protolichus Mégnin et Trouessart, 1884, described by E. Trouessart over a century ago, and which have been transferred to these genera. Two new species are described: Apexolichus psephoti sp. nov. from Psephotus varius Clark A.H., 1910 (type host) and P. haematonotus (Gould, 1838); and Titanolichus triangulifer sp. nov. from Barnardius zonaris (Shaw, 1805) (type host) and Northiella haematogaster (Gould, 1838). New synonymies are proposed: Apexolichus splendens (Favette et Trouessart, 1904) syn. nov. is a junior synonym of A. velifer (Trouessart, 1899); A. distensis (Favette et Trouessart, 1904) syn. nov. is a junior synonym of A. affinis (Mégnin et Trouessart, 1884). Apexolichus platycerci (Mironov, Dabert et Proctor, 2003) comb. nov. is a new combination for this species, which was formerly placed in the genus Titanolichus. Phylogenetic analysis (MP) confirms the monophyly of the genera Apexolichus and Titanolichus. Both of these genera, together with the monotypic genus Sideroferus Gaud et Atyeo, 1996 (being a sister group of Titanolichus), form a clade within the Protolichus generic group and are restricted in their host associations to parrots of the tribe Platycercini (Psittacidae, Psittacinae), members of which occur in the Australia and Indo-Malayan region. Representatives of each genus are restricted to a particular genus or a few genera of Platycercini. Host associations of these genera are briefly discussed.
