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.
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 species of poorly known feather mite genus Neumannella Trouessart, 1916 (Acari, Astigmata) are described from tataupa tinamou Crypturellus tataupa (Temminck, 1815) (Aves, Tinamiformes): Neumannella astacus sp. nov. and N. tataupai sp. nov. The present state of knowledge about this genus is briefly discussed.
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.
A new representative of the subfamily Analginae, Anhemialges mironovi sp. nov., collected from feathers of the Savi’s warbler Locustella luscinoides (Savi, 1824) (Passeriformes, Sylviidae) from the region of South Dobrudzha (Bulgaria), is described. This species is most similar to A. gaudi Mironov, 2009. The new species differs from A. gaudi by the following features in males: the incision in the interlobar membrane is longer, the gastral shield is split into two parts, and the hysteronotal shield bears a crescent-shaped subtegumental sclerotisation.
A new species of the poorly known feather mite genus Anhemialges Gaud, 1958 is described from the Common Chiffchaff Phylloscopus collybita. Anhemialges bakeri sp. nov. differs from all other species of the genus by the shape of setae w and s on tarsi III, which are hair-like and slightly thickened in basal and median parts. In all other described species of Anhemialges, setae w and s on tarsi III are blade-like or shaped as thick spines. The lack of leg III hypertrophy is discussed and interpreted as characteristic feature of the species rather than male homeomorphy. Remarks about the recent and possible species richness of the genus Anhemialges are given.
Neumannella skorackii, a new species of the feather mite family Dermoglyphidae (Acari, Astigmata) is described from the Red-winged Tinamou Rhynchotus rufescens (Temminck, 1815) (Aves, Tinamiformes) from Paraguay and a key to all known species of the genus is provided. The phylogenetic relationships (MP analysis of 25 morphological characters) between Neumannella species along with the evolutionary history of host-parasite associations revealed by Jungle reconciliation method are reconstructed. Relatively low cospeciation contribution to the recent host-parasite associations is discovered.
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.
A new genus and species of feather mite, Hemitriccodectes furcatus gen. nov., sp. nov., is described from passerines of the genus Hemitriccus from Brazil: Hemitriccus furcatus, H. margaritaceiventer and H. striaticollis (Tyrannidae). The new genus belongs to the Pterodectes generic complex and most clearly differs from previously established genera of this complex by the following combination of features: trochanteral setae sRIII are present, and solenidia σ are absent from genua III. The new genus also lacks dorsal hysteroromal setae c1.
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).
Syringoplutarchusia, a new genus of the syringicolous feather mite family Syringobiidae (Pterolichoidea), is described based on a single new species, S. nordmanni sp. nov., collected from the feather quills of a museum specimen of the Black-winged Pratincole Glareola nordmanni Fischer, 1842 (Glareolidae). Absence of adanal discs and complete reduction of setae d and e on tarsi IV in males of the new genus is unique in this family. The highly elongated body shape of both sexes is most similar to the genera Plutarchusia Oudemans, 1904 and Paidoplutarchusia Dabert, 2003 but strong sclerotization of coxal fields and hypertrophied posterior legs with variously shaped apophyses resemble more advanced syringobiid mites, e.g. Syringobia Trouessart et Neumann, 1888. Syringoplutarchusia represents the first syringobiid from this host family. The taxonomic status of the new taxon is discussed.
