A new mange mite species, Macropodicoptes mironovi n. g., n. sp. (Acariformes: Sarcoptidae), is described from Wallabia bicolor (Desmarest) (Diprotodontia: Macropodidae) from the Taronga Western Plains Zoo at Dubbo, NSW, Australia. This is the fourth species and third genus allocated to the sarcoptid subfamily Diabolicoptinae, whose representatives exclusively parasitise marsupials. The new genus differs from Diabolicoptes Fain & Domrow, 1974, in both sexes, by the proportions of the gnathosoma, the shape of many hysterosomal setae and the absence of setae e1, pRII-II, sRIII and solenidion ω3I; and, in males, by the lack of fusion of coxal apodemes I.

A new monobasic genus of parasitic mites, Phalarophilus fulicarius gen. nov., sp. nov. (Acariformes, Syringophilidae) is described from feather quills of Phalaropus fulicarius (Linnaeus) (Charadriiformes, Scolopacidae) from USA. Females of the new genus differs from those of the genus Bochkovia Skoracki et OConnor, by having the rounded posteriorly stylophore, edentate movable cheliceral digits, propodonotal setae arranged 2-1-1-2, thin and smooth dorsal setae of the idiosoma, smooth dorsal setae of legs I and II, and by the presence of setae vsI; males are distinguished by the presence of the propodonotal setae arranged 2-1-1-1-1. Additionally, two new syringophilid species recorded from aquatic birds in North America and three new host associations of these mites are recovered. [ABSTRACT FROM AUTHOR]

Four new syringophilid species of Syringophiloidus Kethley, 1970 are described from North American passerines: S. zonotrichia n. sp. from Zonotrichia albicolis (Gmelin) (Emberizidae) on Texas; S. jackowiaki n. sp. from Poecile carolinensis (Auduborn) (Paridae) in Texas; and S. xanthocephalus n. sp. from Xanthocephalus xanthocephalus (Bonaparte) (Icteridae) and S. agelaius n. sp. from Agelaius phoeniceus Linnaeus (Icteridae), both from Arizona. Spizella breweri (Cassin) (Emberizidae) from California is a new host for Syringophiloidus sialius Skoracki, Flannery & Spicer, 2009; and Melospiza lincolnii (Auduborn) (Emberizidae) from Texas and Vermivora ruficapilla (Wilson) (Parulidae) from California are new hosts for S. seiuri (Ckark, 1964). S. daberti Bochkov, Fain & Skoracki, 2004 from Passerina ciris Linnaeus (Cardinalidae) is recorded in the USA for the first time. A table with the host associations and distribution of all of the North American species of Syringophiloidus is given. [ABSTRACT FROM AUTHOR]

Three new species of parasitic mites of the genus Neharpyrhynchus Fain (Acariformes, Harpirhynchidae) are described from Neotropical birds: N. chlorospingus sp. n. from Chlorospingus pileatus (Passeriformes, Emberizidae) from Costa Rica, N. mironovi sp. n. from Dacnys cayana (Passeriformes, Thraupidae) and N. tangara sp. n. from Tangara cayana (Thraupidae) both from Brazil. Neharpyrhynchus trochilinus (Fain) is recorded from 3 new host species of the family Trochilidae (Apodiformes), Panterpe insignis and Eugenes fulgens from Costa Rica, and Amazilia lactea from Brazil. Emended diagnosis of the genus and a key to species are provided; all records of Neharpyrhynchus species are summarized. [ABSTRACT FROM AUTHOR]

A new species of syringophilid mites, Mironovia lagopus sp. nov. (Acari: Syringophilidae) is described from feather quills of the rock ptarigman Lagopus muta (Montin) (Phasianidae) from Iceland. Females of this new species differ from the closely related Mironovia rouloul Skoracki and Sikora by setae d2, which are subequal or 1.1-1.2 times shorter than setae e2 (vs. d2 1.4-1.5 times longer than e2 in Mironovia rouloul) and by setae ag1, which are 1.3-1.5 times shorter than ag2 (vs. ag1 1.7-1.8 times shorter than ag2). The postembryonic stages of this new species are figured and described in details. In ontogeny of Mironovia spp., the observed pattern of setal appearance is not different from the pattern in other galliform-associated genera such as Syringophilus and Colinophilus, with exception for tarsal setae p'I, II which are absent in protonymphs. The key to all four species of the genus Mironovia is also provided. [ABSTRACT FROM AUTHOR]

The monophyly of the family Lobalgidae comprising the genera Lobalges, Echimytricalges and Coendalges is tested using morphological characters and the maximum parsimony approach. Representatives of all subfamilies of the family Psoroptidae, the families Pyroglyphidae (Paralgopsis) and Psoroptoididae (Psoroptoides), and most families of the superfamily Sarcoptoidea were used as close outgroups, with Ptiloxenus (Ptiloxenidae) and Acarus (Acaridae) selected as distant outgroups. The analysis revealed polyphyly of the family: the two lobalgid genera Lobalges and Echimytricalges appear as sister groups, whereas the genus Coendalges is a member of a clade comprising genera of the psoroptid subfamily Psoralginae. The composition of the family Lobalgidae is here limited to these two genera, and the genus Coendalges is placed in the subfamily Psoralginae (Psoroptidae). A taxonomic revision of the family Lobalgidae is given, including descriptions of two new species, Echimytricalges lonchothrix sp.n. and E. proechimys sp.n. We also validate the species Echimytricalges whitakeri Fain and Ritzi, which had previously been a nomen nudum. [ABSTRACT FROM AUTHOR]

The external morphology of all postembryonic instars of the harpirhynchid mite Harpyrhynchoides rubeculinus (Cerny and Sixl, 1971) (Acari: Prostigmata: Harpirhynchidae) parasitizing the European robin, Erithacus rubecula (L.) (Passeriformes: Muscicapidae), in the Czech Republic is described and figured in detail. [ABSTRACT FROM AUTHOR]

The external morphology of 2 closely related mite families, Cloacaridae and Epimyodicidae (Acari: Prostigmata), comprising highly specialized endoparasites of vertebrates, is analyzed. These mites exhibit strong regression of many structures ancestrally present in other Prostigmata as a consequence of their endoparasitic mode of life. The relationships of these 2 families with other taxa in the infraorder Eleutherengona are still not clear. Our reinterpretation of the chelicerae as unfused precludes inclusion of this lineage in the Cheyletoidea as proposed previously. A new superfamily, Cloacaroidea superfam. nov., incertae sedis, within the infraorder Eleutherengona is established for these 2 families, and their host-parasite relationships are briefly discussed. A new cloacarid species, Caminacarus dawsoni n. sp., from Graptemys pseudogeographica (Testudines: Emydidae) from the United States is also described. [ABSTRACT FROM AUTHOR]

Abstract: A phylogenetic reconstruction of feather mites of the epidermoptid complex (Analgoidea: Epidermoptidae, Dermationidae, and Knemidocoptidae) was carried out by methods of parsimony-based cladistics. The epidermoptid complex splits into two major branches, Epidermoptidae and Dermationidae. The family Dermationidae is monophyletic, while the Epidermoptidae, as previously defined, is paraphyletic. The family Knemidocoptidae is reduced to the subfamilial rank because it arises from the core of the Epidermoptidae. The subfamily Myialginae Trouessart, 1906 stat. resur. is restored within the Epidermoptidae. The aberrant genera Lukoschuscoptes and Apocnemidocoptes are moved from Knemidocoptidae to Epidermoptidae and Dermationidae, respectively. A hypothesis explaining main trends in morphological and ecological adaptations to parasitism on birds within the epidermoptid complex is proposed. New taxonomic diagnoses for higher taxa (families and subfamilies) are provided, and three new genera—Archemyialges gen. n., Hemimyialges gen. n. (Epidermoptidae), and Trochiloptes gen. n. (Dermationidae)—and a new subfamily—Apocnemidocoptinae—are established. [Copyright &y& Elsevier]

Background: The cox1-barcoding approach is currently extensively used for high-throughput species delimitation and discovery. However, this method has several limitations, particularly when organisms have large effective population sizes. Paradoxically, most common, abundant, and widely distributed species may be misclassified by this technique. Results: We conducted species delimitation analyses for two host-specific lineages of scab mites of the genus Caparinia, having small population sizes. Cox1 divergence between these lineages was high (7.4–7.8%) while that of nuclear genes was low (0.06–0.53%). This system was contrasted with the medically important American house dust mite, Dermatophagoides farinae, a globally distributed species with very large population size. This species has two distinct, sympatric cox1 lineages with 4.2% divergence. We tested several species delimitation algorithms PTP, GMYC, ABGD, BPP, STACEY and PHRAPL, which inferred different species boundaries for these entities. Notably, STACEY recovered the Caparinia lineages as two species and D. farinae as a single species. BPP agreed with these results when the prior on ancestral effective population sizes was set to expected values, although delimitation of Caparinia was still equivocal. No other cox1 species delimitation algorithms inferred D. farinae as a single species, despite the fact that the nuclear CPW2 gene shows some evidence for introgression between the cox1 groups. This indicates that the cox1-barcoding approach may result in excessive species splitting. Conclusions: Our research highlights the importance of using nuclear genes and demographic characteristics to infer species boundaries rather than relying on a single-gene barcoding approach, particularly for putative species having large effective population sizes.

We report two host-specific lineages of scab mites of the genus Caparinia, parasitizing European and African hedgehogs. Based on morphology, these mite lineages are closely related sister groups. The morphological differences, however, are subtle and do not provide clear-cut evidence for the existence of separate species. CO1 divergence between these lineages was 7.4-7.8%, well above the CO1 barcoding gaps or thresholds commonly used to separate species, whereas divergence of five nuclear genes was very low, 0.06-0.53%, suggesting that these lineages could belong to a single species with gene flow between them. Thus, there is a conflict between the mitochondrial (CO1) gene and nuclear genes (i.e mito-nuclear discordance). We attribute this conflict to the 'gray zone' where species delimitation is ambiguous due to substantial gene flow. We also report another 'gray zone' species, Psoroptes ovis (a species of veterinary importance), whose within-species CO1 distances reached 6.0%. We provide a detailed morphological description and figures of C. ictonyctis stat. res. from the African hedgehog, using light and SEM microscopy and give morphometric data for this species and its sister species, Caparinia tripilis from Europe. For all known species of Caparinia, we document their host associations and give a key to species of the world based on results of our morphological and molecular analyses and a nearly exhaustive study of museum specimens.

The fur mite genus Dubininetta Fain & Lukoschus, 1978 (Acariformes: Listrophoridae) represented by ectoparasites of moles (Soricomorpha: Talpidae) is revised. An amended diagnosis of this genus is provided. Two new species are described from moles in Vietnam: Dubininetta euroscaptor n. sp. from Euroscaptor parvidens (Miller) and Dubininetta abramovi n. sp. from Euroscaptor subanura Kawada, Son & Can. The insufficiently described D. taiwanensis (Fain & Lukoschus, 1978) from Mogera insularis (Swinhoe) (type-host) is redescribed based on the type-specimens and numerous newly collected in the Russian Far East specimens from Mogera robusta Nehring. The host ranges are considered for all species of Dubininetta. A key to the five species presently known in this genus is provided.

Eleven species of myocoptid mites (Acariformes: Myocoptidae) are recorded from African rodents. Among them, three species are described as new for science: Myocoptes lophuromys sp. nov. from Lophuromys woosnami Thomas, 1906 (Rodentia: Muridae) from Uganda, Trichoecius hylomyscus sp. nov. from Hylomyscus anselli Bishop, 1979 (Rodentia: Muridae) from Tanzania (type host and locality) and Hylomyscus stella (Thomas, 1911) from Gabon, and Trichoecius faini sp. nov. from Hylomyscus arcimontanus Carlton and Stanley, 2005 from Tanzania. Gliricoptes graphiuri Fain, 1970 syn. nov. is synonymized with Gliricoptes vulcanorum Fain, 1970, and the female of Trichoecius angolensis Fain, 1972 is described for the first time. New hosts and localities are provided for four species: Myocoptes grammomys Fain, 1970 from Grammomys dryas (L., 1758) (Rodentia: Muridae) from Burundi and Uganda, Myocoptes spinulatus Fain, 1970 from Dendromus mystacalis (Heuglin, 1863) (Rodentia: Muridae) from Tanzania, Crinicastor congolensis Fain, 1970 from Grammomys macmillani (Wroughton, 1907) (Rodentia: Muridae) from Tanzania, and Trichoecius otomys Fain, 1970 from Otomys typus (Heuglin, 1877) (Rodentia: Muridae) from Uganda.

A new species of parasitic mites, Myocoptes (Comyocoptes) nesokia sp. nov. (Acariformes: Myocoptidae) is described from Nesokia indica (Gray, 1830) (Rodentia: Muridae) from Pakistan. Females of this species differ from the morphologically similar species, Myocoptes (Comyocoptes) striatus Fain, 1970, by the presence of a verrucose pattern in the middle part of the hysteronotum, longer setae cp (120-140 μm vs. 55-60 μm), and by the absence of scales on the opisthosomal cuticle posterior to the level of setal bases ps3.

Mites of the family Myocoptidae (Acariformes: Sarcoptoidea) of the former USSR are revised based on the collection of the Zoological Institute RAS (St. Petersburg, Russia). Seventeen described species are recorded. Four species are described as new for science: Trichoecius dubininae sp. nov. from Lasiopodomys gregalis (Pallas) (Rodentia: Cricetidae) from Russia (Chelyabinsk Prov., type locality), Kazakhstan and Kirghizia, T. lemmus sp. nov. from Lemmus sibiricus (Kerr) (Rodentia: Cricetidae) from Russia (Taymyr peninsula), T. meriones sp. nov. from Meriones meridianus (Pallas) (Rodentia: Muridae) from Turkmenia, and Myocoptes meriones sp. nov. from Meriones tamariscinus (type host) from Kirghizia (type locality) and Meriones libycus (Lichtenstein) from Tajikistan. In addition, the presence of 7 more species in the fauna of the former USSR is considered highly probable. Myocoptids of the former USSR represent all 6 genera currently recognized in the family. Keys to species, their hosts and localities are provided and all data are summarized in tabular format. A new name Apocalyptoides nom. nov. is proposed for the preoccupied generic name Apocalypsis Bochkov, 2010 not Butler (1876).

Host associations of permanent ectoparasitic mite Marsupialges misonnei Fain, 1963 (Acariformes: Psoroptidae: Marsupialginae) are analyzed. This species was first recorded from an ethanol-preserved museum specimen of Caluromys philander (Linnaeus, 1758) (Didelphimorphia: Didelphidae) originating from French Guiana. We discovered specimens of M. misonnei from both species known in the carnivore genus Nasua (Carnivora: Procyonidae): N. narica (Linnaeus, 1766) from Panama (collected in the field) and N. nasua (Linnaeus, 1766) from Brazil (collected from dry museum specimen). Two alternative hypotheses about an initial host of this mite (bare-tailed woody opossum or coatis) are discussed. We argue that M. misonnei was originally parasitic on Nasua spp. and occasionally contaminated C. philander from these hosts in the collecting process.

A new species Crocidurobia faini n. sp. (Acariformes: Myobiidae) recorded on Crocidura denti Dollman (type-host) (Soricomorpha: Soricidae), Crocidura cf. niobe Thomas, Crocidura cf. littoralis Heller, and Crocidura sp. from DR Congo is described. This new species differs in both sexes from all other species of the subgenus Crocidurobia Jameson, 1970 by short setae c2, more than three times shorter than setae se. Females of the new species differ from those of the close species Crocidurobia toroensis Dusbabek, 1983 by setal bases e2 situated slightly anterior to the level of setal bases e1; males of the new species differ by the genital shield bearing five pairs of setae situated anterior to the level of setal bases d1.

The fur-mite genus Soricilichus Fain, 1970 (3 species) (Acariformes: Chirodiscidae) represented by permanent symbionts of the African shrews of the subfamily Crocidurinae (Soricomorpha: Soricidae) is revised. The external morphology of these species was investigated with light and scanning electron microscopy. Based on the type specimens and newly obtained samples, 2 recognized species, S. scutisorex Fain, 1970 from Scutisorex somereni Thomas and S. kivuensis Fain, 1981 from Crocidura sp.-both are from DR of Congo-are redescribed. A new species S. sylvisorex sp. nov. found on shrews of the genera Sylvisorex (S. granti Thomas (type host), S. lunaris Thomas, S. vulcanorum Hutterer and Verheyen) and Crocidura (C. denti Dollman, C. cf. niobe, Crocidura sp.), collected in the DR Congo is also described. An amended generic diagnosis, including description of female immature stages, and a key to species are provided.

Keys to all harpirhynchine genera and all their species occurring in the New World are also given. A list of all harpirhynchine species and their hosts is compiled.

Two new mite species of the subfamily Harpirhynchinae Dubinin, 1957 (Acariformes: Harpirhynchidae) are described from passerine birds (Aves: Passeriformes): Harpirhynchoides artamus n. sp. from Artamus fuscus Vieillot (Artamidae) from an unknown locality in South Asia and Neharpyrhynchus domrowi n. sp. from three host species of the family Meliphagidae, Acanthorhynchus tenuirostris (Latham) (type-host) from Australia (New South Walles), Ptiloprora perstriata (De Vis) and Myzomela rosenbergii Schlegel from Papua New Guinea.

Tachornithoglyphus gen. nov. (Acariformes: Pyroglyphidae) is established for Tachornithoglyphus tachornis (Cruz, Cuervo and Dusbabek, 1984), comb. nov. (transferred from Guatemalichus), collected from nests of the Antillean palm swift, Tachornis phoenicobia (Apodiformes: Apodidae) in Cuba. The new genus differs from the other four genera of the subfamily Guatemalichinae, Guatemalichus Fain and Wharton, 1970, Pottocola Fain, 1971, Fainoglyphus Atyeo and Gaud, 1977, and Capitonocoptes Fain and Gaud, 1984, mainly by having the length of solenidion σ1 of genu I less than one-third that of the segment (vs. solenidion σ1I at least half as long as genu I), by the absence of famulus ε on tarsus I (vs. present), and by coxal apodemes Ia separated from each other and contiguous to the lateral parts of the epigynal arch (vs. posterior tips of apodemes Ia fused to each other and with the median part of the epigynal arch, or separated and contiguous to or fused with the median part of the epigynal arch). A detailed redescription of adults and tritonymphs of T. tachornis is provided.

Carcinopodacarus polymorphus gen. n. et sp. n. (Acariformes: Dermationidae: Dermationinae) is described from the guira cuckoo Guira guira (Gmelin) (Cuculiformes: Cuculidae) in Brazil. The new genus differs from the closest genus, Psittophagoides Fain, 1964, by the following features: in both sexes, the anterior spines of trochanters I and II are absent (vs present in Psittophagoides), setae d2 are distinctly developed (vs only alveoli), and genual setae mGI are absent (vs present); in males, the hysteronotal shield is split transversally at the level of trochanters III (vs hysteronotal shield entire); in females, the platelets situated posterior to the propodonotal shield are absent (vs present), the metapodosomal sclerites are present (vs absent), and the adanal shields are fused anteriorly to each other (vs separated from each other). In this species, andropolymorphism is detected for the first time for the family. It involves various characters but the most impressive feature is the structure of legs III. In hetero- and mesomorphic males, these legs are strongly hypertrophied and have a distinct ventral spur on femora III; in homeomorphic males, legs III are not modified and subequal to legs IV.

A new species of the genus Lemuralges Fain, 1963 (Acariformes: Psoroptidae: Makialginae) is described from the Malagasy lemur Propithecus diadema (Bennett) (Primates: Indriidae) based on all postembryonic instars. This new species differs from the only known species in this genus, Lemuralges intermedius Fain, 1963, by the following features: both sexes of L. propithecus sp. n. show a pair of medioventral projections of the subcapitulum (vs without projections in L. intermedius) and the propodonotal shield is slightly ornamented (vs unornamented); in males the hysteronotal shield is completely covered by longitudinal striae (vs median part without striae), setae c2 are 120-140 µm long (vs 200-210 µm long), and femur III has a short transverse furrow dorsally (vs a longitudinal furrow); in females, setae h2 are, at least, 2 times shorter than h3 (vs slightly longer, or subequal to, h3), tibia IV has a ventro-apical projection (vs without projection). Larvae and protonymphs of the new species show some unique developmental delays. Female and male tritonymphs differ by their external morphology.

Galagocheles Fain, 1979 (Acari: Cheyletidae), comprising permanent parasites of African prosimian primates (Galagonidae), is revised. An amended diagnosis of the genus based on characters of adults and immatures is given. The type-species, G. lemuricola (Lawrence, 1948), from Otolemur garnetti (Ogilby) (type-host) and O. crassicaudatus Geoffroy, is redescribed, and G. lawrencei n. sp. is described from Galago senegalensis Geoffroy (type-host) and G. moholi Smith. The new species differs from G. lemuricola by its smaller body size, the obtuse posterior end of the opisthosoma in males, and by fine, nude setae ps3 in females. The systematics of the cheyletid tribe Niheliini and host-parasite associations of its species are briefly discussed. The tribe Criokerontini is included to the tribe Niheliini. It is suggested that the ancestors of the tribe Niheliini were predaceous cheyletids associated with the nests of arboreal mammals, and the association of Nihelia spp. on mongooses (Herpestidae) is the result of the host-switching from some ancient arboreal mammal.
