Feather mites of the genus Lopharalichus Gaud & Atyeo, 1996 (Pterolichidae: Pterolichinae), formerly containing three described species, are associated with New World parrots (Psittaciformes: Psittacidae) of the subfamily Arinae. Three new species of this genus are described: Lopharalichus tuimsp. nov. from Forpus xanthopterygius (Spix, 1824), L. spinosussp. nov. from Ara ararauna (Linnaeus, 1758), and L. chiririsp. nov. from Brotogeris chiriri (Vieillot, 1818). Type specimens of the previously described Lopharalichus species were examined, and a key to the known species is provided.
... The Nycteridocaulus generic group (Proctophyllodinae) is one of two major and early derivative phylogenetic lineages of the subfamily, whose representatives are mainly associated with suboscine passerines in the New World (Tyrannides) (Klimov et al., 2017;Mironov & Bermúdez, 2020). To date, this generic group has included 32 species in eight genera: Anisophyllodes Atyeo, 1967, Armophyllodes Mironov & Bermúdez, 2018, Atrichophyllodes Hernandes et al., 2007, Dendrocolaptobius Mironov & Bermúdez, 2020, Diproctophyllodes Atyeo, 1966, Hemipterodectes Berla, 1959, Nycteridocaulus Atyeo, 1966, and Rupicolacarus Atyeo, 1972 (Atyeo, 1966(Atyeo, , 1967(Atyeo, , 1969(Atyeo, , 1972Atyeo & Gaud, 1968;Berla, 1959;De Alzuet & Brandetti, 1986;Hernandes, 2014;Hernandes & Valim, 2014;Hernandes et al., 2007;Mironov & Bermúdez, 2018, 2020Mironov & González-Acuña, 2009;.

Three new feather mite species of the Nycteridocaulus generic group (Proctophyllodidae: Proctophyllodinae) are described from passerines in Panama: Atrichophyllodes myrmotherulaesp. n. from the Slaty Antwren, Myrmotherula schisticolor (Lawrence) (Thamnophilidae), Nycteridocaulus apanaskevichi sp. n. from the Grey-breasted Wood Wren, Henicorhina leucophrys (Tschudi) (Troglodytidae), and N. empidonicussp. n. from the Yellowish Flycatcher Empidonax flavescens Lawrence (Tyrannidae). Nycteridocaulus apanaskevichi, presenting the second record of the genus from a host of oscine passerines, differs from N. guaratubensis Hernandes, 2014 in having the anterolateral extensions of the prodorsal shield rounded and the hysteronotal shield lacking any ornamentation. Males of N. empidonicus differ from N. myiobius Mironov, 2017 in having the supranal concavity open posteriorly and tarsus IV with rounded apical process; and females are distinguished by macrosetae h2 having long filiform apices. Males of A. myrmotherulae most clearly differ from A. mentalis Hernandes et al. 2007 in having the terminal lamellae rectangular and tarsus IV with triangular ventral process, and females are distinguished in having a noticeably longer idiosoma, 400–430 μm long. Comments on systematics and host associations of the genera Atrichophyllodes and Nycteridocaulus are provided.
... In heteromorph males, legs IV are also noticeably thicker than legs III, while in homeomorphs, legs III and IV are subequal in size. Females are practically indiscernible from most proctophyllodine genera having the same features in both sexes and the hysteronotal shield completely split into anterior and lobar parts in females (Diproctophyllodes Atyeo, 1966, Hadrophyllodes Atyeo, 1971, Hemipterodectes Berla, 1959, and Nycteridocaulus Atyeo, 1966; only strongly pronounced ovate lacunae on the hysteronotal shield could be more or less suitable as genus-level diagnostic characters in the case when males are not found. ...
... Genus Tanyphyllodes Atyeo, 1966 The genus Tanyphyllodes previously included a sole species Tanyphyllodes scelorchilae Atyeo, 1966 described from Scelorchilus rubecula (Kittlitz, 1830) (Rhinocryptidae) from Chile (Atyeo 1966). This genus most clearly differs from other known proctophyllodine genera by the following characters in males: the opisthosoma is strongly elongated (over 1/3 of total length of idiosoma), with strong lateral ledges bearing setae ps2; the distal part of opisthosoma (posterior to these ledges) is much narrower than anterior one and forms opisthosomal lobes continuing in large lanceolate or tongue-like terminal lamellae with pinnate pattern. ...

The generic rev1s1on of the Pterodectinae, new subfamily of the Proctophyllodidae, is based on 88 named and over 160 new species. Included are morphology, host-parasite relationships, diagnoses of four named and eight new genera, and illustrations of each type species. The named genera are: Anisodiscus Gaud and Mouchet, 1957; Montesauria Oudemans, 1905; Proterothrix Gaud, 1968; Pterodectes Robin, 1877. The new genera and their type species are: Dolichodectes, Proctophyllodes (Pterocolus) edwardsi Trouessart, 1885; Megalodectes, Proctophyllodes (Pterodectes) major Trouessart, 1885; Neodectes, Proctophyl/odes (Pterodectes) securiclatus Trouessart and Neumann, 1888; Pedanodectes, Pterodectes hologaster Gaud, 1953; Syntomodectes, Proctophyllodes (Pterodectes) selenurus Trouessart, 1885; Toxerodectes, Pterodectes gladiger hastifolia Trouessart, 1899; Trochilodectes, Proctophyllodes (Pterodectes) trochilidarum Trouessart, 1885; Xynonodectes, Proctophyllodes (Pterodectes) gracilior Trouessart, 1885. The subgenus Pterodectes (Proterothrix) Gaud, 1968, is elevated to genus. Eighty-eight species are assigned to the appropriate genera, six species are unassigned, Pterodectes rotifer (Trouessart and Neumann), 1888, is re-assigned to the genus Trouessartia, and Pterodectes armatus Banks, 1909, is assigned to the genus Proctophyllodes. New synonymy: Montesauria cylindrica (Robin), 1877 = Pterodectes corvincola Oudemans, 1905.

Two new feather mite species, Nycteridocaulus sulcatus sp. n. and Tyranniphyllodes empidonicus sp. n. (Astigmata: Proctophyllodidae), are described from the Yellow-bellied Flycatcher, Empidonax flaviventris (Passeriformes: Tyrannidae), in Canada. The clearest distinguishing characteristic of N. sulcatus is the structure of the supranal concavity in males, which is parallel-sided, heavily sclerotized and opened posteriorly. Tyranniphyllodes empidonicus readily differs from the only previously known species, T. pitangi Hernandes et al. 2007, by the absence of setae d1 in both sexes and in having strongly elongated epimerites IVa and the genital sheath in males not extending to the tip of the aedeagus, and long anterolateral extensions of the prodorsal shield in females. This is the first record of the genus Tyranniphyllodes in North America.
... In their generic revision of the Pterodectinae, Park & Atyeo (1971a) provided uniform diagnoses for all genera including eight newly established ones, and revised their species content. Other taxonomic works led by W.T. Atyeo and J. Gaud dedicated to proctophyllodids focused mainly on the two fields: pterodectines living on hummingbirds (Trochilidae, e.g. Park & Atyeo 1971b, 1972a, 1972b, 1973a, 1973b, 1974a, 1974b, 1975 and proctophyllodines associated with birds of tropical regions, mainly with suboscine passerines (Gaud & Berla 1963;Atyeo 1966aAtyeo , 1966bAtyeo , 1967aAtyeo , 1967bAtyeo , 1969Atyeo , 1971aAtyeo , 1971bAtyeo , 1971cAtyeo , 1972, 1970a, 1970b1971a, 1971bGaud & Fain 1990).

... The earliest purposeful investigations of proctophyllodines of the New World were undertaken in Brazil by Berla ( , 1959bBerla ( , 1959c. Then, Atyeo and Gaud published a series of works on proctophyllodines associated with the suboscines in various countries of South and Central America (Gaud & Berla 1963;Atyeo 1966aAtyeo , 1966bAtyeo , 1967aAtyeo , 1967bAtyeo , 1971aAtyeo , 1971bAtyeo , 1971c, 1970a, 1970b, 1971a, 1971b. Significant contribution to the knowledge on proctophyllodines of the New World was made by the revision of the genus Proctophyllodes (Atyeo & Braasch 1966), mainly for the USA and Mexico, and by the review of mites associated with woodcreepers (Furnariidae: Dendrocolaptinae) in South and Central America (Kudon 1982e). ...

A total of 25 proctophyllodine species of six genera have been recorded, of which 19 new species are described: Anisophyllodes cuneiformis sp. n. from Sittasomus griseicapillus (Vieillot) (Furnariidae), Atrichophyllodes latilobus sp. n. from Hylophylax naevioides (Lafresnaye) (Thamnophilidae), Nycteridocaulus attila sp. n. from Attila spadiceus (Gmelin, JF) (Tyrannidae), N. hylophylax sp. n. from Hylophylax naevioides (Lafresnaye) (Thamnophilidae), N. ketourus sp. n. from Thryophilus rufalbus (Lafresnaye) (Troglodytidae), N. leptopogoni sp. n. from Leptopogon superciliaris Tschudi (Tyrannidae), N. myiobius sp. n. from Myiobius sulphureipygius (Sclater, PL) (Tyrannidae), N. myioborus sp. n. from Myioborus miniatus (Swainson) (Parulidae), N. platyrinchi sp. n. from Platyrinchus cancrominus Sclater, PL and Salvin (Tyrannidae), Platyacarus caulifer sp. n. from Glyphorynchus spirurus (Vieillot) (Furnariidae), Pl. dendrocinclae sp. n. from Dendrocincla homochroa (Scalter, PL) (Furnariidae), Pl. dendrocolapti sp. n. and Pl. picumnus sp. n. from Dendrocolaptes picumnus Lichtenstein, MHK (Furnariidae), Pl. sclerurus sp. n. from Sclerurus mexicanus Sclater, PL (Furnariidae), Proctophyllodes arremoni sp. n. from Arremon brunneinucha (Lafresnaye) (Emberizidae), Pr. euphoniae sp. n. from Euphonia hirundinacea Bonaparte (Fringillidae), Pr. vesicularis sp. n. from E. anneae Cassin (Fringillidae), Pr. parkesiae sp. n. from Parkesia motacilla (Vieillot) (Parulidae), and Pr. strictophyllus sp. n. from Coereba flaveola (Linnaeus) (Thraupidae). The female of Anisophyllodes pipromorphae Atyeo, 1967, previously known from two forms of males only, is described for the first time. Five new host associations are recorded for the following mites: Anisophyllodes pipromorphae from Mionectes olivaceus Lawrence (Tyrannidae), Diproctophyllodes dielytra (Trouessart, 1885) from Chiroxiphia linearis (Bonaparte) and Corapipo altera Hellmayr (Pipridae), Nycteridocaulus pectinatus Atyeo, 1966 from Tolmomyias sulphurescens (von Spix) (Tyrannidae), and Proctophyllodes thraupis Atyeo and Braasch, 1966 from Tangara icterocephala (Bonaparte) (Thraupidae). Two species, Proctophyllodes habiae Atyeo and Braasch, 1966 from Habia rubica (Vieillot) (Cardinalidae) and Platyacarus sittasomi Hernandes et al., 2007 from Sittasomus griseicapillus (Vieillot) (Furnariidae), are recorded in Costa Rica for the first time. New diagnoses and keys to all currently known species are provided for the genera Anisophyllodes Atyeo, 1967, Atrichophyllodes Hernandes et al., 2007, Nycteridocaulus Atyeo, 1966, and Platyacarus Kudon, 1982. Two new species groups, caulifer and minor, are established within the genus Platyacarus. The history of taxonomic investigations of proctophyllodine feather mites is briefly presented. We summarize host associations with passerine birds of the New World for these proctophyllodine genera and species, excluding the genus Proctophyllodes.

Background The common waxbill, Estrilda astrild (L., 1758) (Passeriformes: Estrildidae) is a small passerine bird native to Sub-Saharan Africa that has been introduced into several regions of the world. Results In the present paper, eight mite species (Acariformes) are reported from this host from Brazil, including three species new to science: Montesauria caravela n. sp., M. conquistador n. sp. (Proctophyllodidae), Trouessartia transatlantica n. sp., T. minuscula Gaud & Mouchet, 1958, T. estrildae Gaud & Mouchet, 1958 (Trouessartiidae), Onychalges pachyspathus Gaud, 1968 (Pyroglyphidae), Paddacoptes paddae (Fain, 1964) (Dermationidae) and Neocheyletiella megaphallos (Lawrence, 1959) (Cheyletidae). Comparative material from Africa was also studied. Conclusions These mites represent at least three morpho-ecological groups regarding their microhabitats occupied on the bird: (i) vane mites (Montesauria and Trouessartia on the large wing and tail feathers); (ii) down mites (Onychalges); and (iii) skin mites (Paddacoptes and Neocheyletiella). On one bird individual we found representatives of all eight mite species. Although the common waxbill was introduced to the Neotropical region almost two centuries ago, we demonstrate that it still retains its Old World acarofauna and has not yet acquired any representatives of typical Neotropical mite taxa.

The present study reports associations between feather mites (Astigmata) and birds in an Atlantic Forest fragment in Rio Grande do Norte state, in Brazil. In the laboratory, mites were collected through visual examination of freshly killed birds. Overall, 172 individuals from 38 bird species were examined, between October 2011 and July 2012. The prevalence of feather mites was 80.8%, corresponding to 139 infested individuals distributed into 30 species and 15 families of hosts. Fifteen feather mite taxa could be identified to the species level, sixteen to the genus level and three to the subfamily level, distributed into the families Analgidae, Proctophyllodidae, Psoroptoididae, Pteronyssidae, Xolalgidae, Trouessartiidae, Falculiferidae and Gabuciniidae. Hitherto unknown associations between feather mites and birds were recorded for eleven taxa identified to the species level, and nine taxa were recorded for the first time in Brazil. The number of new geographic records, as well as the hitherto unknown mite-host associations, supports the high estimates of diversity for feather mites of Brazil and show the need for research to increase knowledge of plumicole mites in the Neotropical region.
... The material was cleared and mounted on slides according to the procedure of Flechtmann (1975); the missing setae from a holotype were figured from paratypes. The idiosomal and leg chaetotaxy follow Griffiths et al. (1990) and Gaud (1966), respectively. Measurements are given in micrometers (µm), including scale-bars of the drawings. ...
... Although the species treated herein had been described by Berla quite superficially and incompletely , the classification of these species as members of the genus Pterodectes has been retained in the subfamilial revision made by Park and Atyeo (1971). In the 1950s, there was no well-defined nomenclature for chaetotaxy and other morphological structures of feather mites (Atyeo and Gaud 1966; Griffiths et al. 1990). As a result, many pterodectine species were described as members of the genus Pterodectes (e. g., Gaud and Mouchet 1957). ...

Here, we describe Euroglyphus perico sp. nov. from a nest of a mammal, probably Peromyscus sp. (Rodentia: Cricetidae), from Durango, Mexico. As this new species combines features of the genera Euroglyphus and Gymnoglyphus, Gymnoglyphus is proposed as a junior subjective synonym of Euroglyphus. An updated diagnosis of the genus Euroglyphus and a key to species of the World are provided.

Background The Asian elephant (Elephas maximus), which is an endangered species, harbors several parasites. Among the ectoparasites that it harbors, ear mites of the genus Loxanoetus have the potential to cause external otitis, an inflammation that may also be associated with the presence of other microorganisms. We assessed the relationships between ear mites, nematodes, yeast, bacterial rods, and cocci sampled from the ears of captive Asian elephants in Thailand. In addition, we discuss the possibility that dust-bathing behavior may be triggered by ear mite infestation, and that this in turn may lead to contamination of the ears with soil microorganisms. Methods Legally owned captive Asian elephants (n = 64) were sampled. Ear swabs were individually collected from both ears and microscopically examined for the presence of mites, nematodes, yeast, bacterial rods, cocci, and host cells. Mites and nematodes were identified to species level using morphological and molecular methods. Results Loxanoetus lenae mites were present in 43.8% (n = 28/64) of the animals (19 animals with mites in one ear and nine animals with mites in both ears). Nematodes of the genus Panagrolaimus were detected in 23.4% (n = 15/64) of the animals (10 with nematodes in one ear and five with nematodes in both ears). In adult elephants (Fisher’s exact test, P = 0.0278) and female elephants (Fisher’s exact test, P = 0.0107), the presence of nematodes in both ears was significantly associated with the presence of mites. In addition, higher categorical burdens of nematodes were also significantly associated with the presence of mites (Fisher’s exact test, P = 0.0234) and epithelial cells (Fisher’s exact test, P = 0.0108), and marginally significantly associated with bacterial cocci (Fisher’s exact test, P = 0.0499). Conclusions The presence of L. lenae mites in the ear canals of the Asian elephants was significantly associated with the occurrence of other microorganisms, such as soil nematodes, bacteria and yeasts. The presence of mites in their ears may increase the dust-bathing behavior of elephants which, if confirmed, represents a further paradigmatic example of a parasitic infestation affecting animal behavior.

Hyperpedalloptes Dubinin (Analgoidea: Alloptidae) is one of the most amazing feather mite genera due to the strong hypertrophy of legs I in males, displayed asymmetrically in some species. Each of the three known species occurs on a particular ibis species of the genus Threskiornis (Pelecaniformes: Threskiornithidae). Based on examination of type and additionally collected materials, we (re)describe previously known and newly found male morphs of Hyperpedalloptes species and describe for the first time a female of H. petazophorus (Trouessart). We found that H. titanopedes Dubinin has three discrete morphs of males; those with asymmetrically hypertrophied legs I are considered to be heteromorphs, while males with symmetrically hypertrophied legs I and males without leg hypertrophy correspond to mesomorphs and homeomorphs, respectively. The previously known morphs of H. petazophorus and H. corymbophorus (Trouessart & Neumann) with symmetrically hypertrophied legs I are treated here as mesomorphic males.

We used morphological characters to explore the phylogeny of mammal-associated psoroptidian mites. In both maximum parsimony and Bayesian analyses, the clades uniting Psoroptoidea and Analgoidea–Sarcoptoidea (higher Psoroptidia) were strongly supported, and monophyly of most sarcoptoid families was confirmed. However, the relationships among families of the higher Psoroptidia (Analgoidea and Sarcoptoidea) remained poorly resolved. Two most parsimonious trees were obtained after successive weighting. In these trees, higher Psoroptidia split into two main clusters with Sarcoptoidea in the traditional sense shown as diphyletic. Cluster I consists of two superfamilies: Analgoidea, including Dermationidae, and Psoroptoidea, stat. res.: Psoroptoidinae (Turbinoptidae–Paracoroptinae); (Pandalurinae (Pyroglyphidae–Lobalgidae); Paralgopsidae, stat. nov.–Ptyssalgidae (Epidermoptidae–Psoroptidae). Cluster II consists of the superfamily Sarcoptoidea represented by two lineages: Listropsoralgidae, stat. nov. (Myocoptidae (Rhyncoptidae–Sarcoptidae)) and Dromiciocoptidae, stat. nov. ((Listrophoridae–Atopomelidae) (Chirodiscidae (Gastronyssidae (Pneumocoptidae–Lemurnyssidae)))). We hypothesised that mites of the superfamilies Pterolichoidea, Analgoidea and Psoroptoidea have independently colonised birds with subsequent ancestral shifts of the families Lobalgidae and Psoroptidae and subfamily Paracoroptinae from birds to mammals. Mites of the superfamily Sarcoptoidea switched from nidicoly to parasitism on ancestors of therian mammals and evolved exclusively on this host group.

A new feather mite genus Dendrocolaptobius gen. n. belonging to the Nycteridocaulus generic group (Proctophyllodidae: Proctophyllodinae) is described. The genus includes two species associated with woodcreepers (Furnariidae: Dendrocopaptinae): Dendrocolaptobius cuneiformis (Mironov, 2017) comb. n. previously described from Sittasomus griseicapillus (Vieillot) in Costa Rica; and D. lepidocolapti sp. n. described herein from Lepidocolaptes souleyetii (Lafresnaye) in Panama. The new genus Dendrocolaptobius is clearly distinguished from the other genera of the Nycteridocaulus group in having an inverted genital arch and enlarged bow-shaped basal sclerite in males and the copulatory opening situated dorsally on the lobar region in females.

Two new species of feather mites are described from nightjars (Caprimulgiformes: Caprimulgidae) of Brazil: Hartingiella neotropica sp. n. (Xolalgidae) described from Hydropsalis parvula (Gould) and Paragabucinia brasiliensis sp. n. (Gabuciniidae) from H. albicollis (Gmelin). The former differs from the type species by having, in males, the anterior projections on epimerites III towards setae 3b and the adanal shield bearing setae ps3 present; in both sexes, a pair of small sclerites situated posterior to setae se have flat suprategumental processes. Paragabucinia brasiliensis sp. n. differs from P. petitoti (Gaud et Mouchet, 1959) by the smaller size of the incisions in the internal margins of opisthosomal lobes of males. These mites are the first representatives of corresponding genera described from the Neotropical region. The genus Hartingiella Gaud, 1980 was previously known solely from its type species. Keys to males and females of the genus Paragabucinia Gaud et Atyeo, 1975 are presented. In addition, all previous records of feather mites associated with birds of the order Caprimulgiformes of the world are summarised.

Two new feather mites are described from the Turkey Vulture, Cathartes aura (Linnaeus), in Canada: Ancyralges cathartinus sp. nov. (Analgoidea: Analgidae) and Cathartacarus aurae gen. nov., sp. nov. (Pterolichoidea: Gabuciniidae). Both species of feather mites have their closest relatives among ectoparasites of the Falconiformes. No species of feather mites related to those which have been found on Ciconiiformes are known to parasitize Cathartidae.

Four new species of feather mites are described from birds in Canada: Megniniella ratcliffi sp.nov. (Analgidae) and Metanalges holderi sp.nov. (Analgidae) from the Sora, Porzana carolina (Linnaeus) (Gruiformes: Rallidae): Metingrassia pelecani sp.nov. (Xolalgidae) from the American White Pelican, Pelecanus erythrorhynchos Gmelin (Pelecaniformes: Pelecanidae); and Vingrassia cygni sp.nov. (Xolalgidae) from the Tundra Swan, Cygnus columbianus (Ord) (Ànseriformes: Anatidae). The genus Vingrassia is reinstated from its previous synonymy with the genus Ingrassia based on the presence of an enlarged prodorsal shield in both sexes, by the shape of the idiosoma and the interlobar membrane on the lobar apices in the male, and by the shape of the hysteronotal shield and the absence of setae ps2 in the female.
