We report on the first investigation of feather mites associated with birds living on the Barton Peninsula (King George Island, Antarctica). We found seven feather mite species of the superfamily Analgoidea from four host species. Two new species are described from two charadriiform hosts: Alloptes (Sternalloptes) antarcticussp. nov. (Alloptidae) from Stercorarius maccormicki Saunders (Stercorariidae), and Ingrassia chionissp. nov. (Xolalgidae) from Chionis albus (Gmelin) (Chionidae). Additionally, we provide partial sequences of the mitochondrial cytochrome c oxidase subunit I (COI), which was utilized as a DNA barcode, for all seven feather mite species.

Two new species of feather mites are described from two individuals of the black-tailed godwit, Limosa limosa (Linnaeus, 1758), in Korea: Alloptes (Conuralloptes) neolimosaesp. nov. (Analgoidea, Alloptidae) and Phyllochaeta limosaesp. nov. (Pterolichoidea, Syringobiidae). Males of A. (C.) neolimosaesp. nov. are distinguished from A. (C.) limosae in having the hysteronotal shield with a straight anterior margin, setae h2 enlarged and slightly flattened in the basal half, and the terminal lamella monotonously transparent without sclerotized patches; females differ in having legs IV with ambulacral discs extending to or slightly beyond the level of setae f2. The discovery of P. limosaesp. nov. represents the first record of the feather mite genus Phyllochaeta on godwits of the genus Limosa Brisson, 1760 (Scolopacidae, Limosinae). Males of P. limosaesp. nov. are distinguished from P. secunda in having the terminal cleft semi-ovoid with a length-to-width ratio of 1.7, and the terminal membranes with 15 or 16 finger-shaped denticles; females differ in having the hysteronotal shield bearing faint longitudinal striations in the posterior third and lacking lacunae, and setae c1 situated posterior to the level of setae c2. Additionally, we obtained partial sequences of the mitochondrial cytochrome c oxidase subunit I (COI) gene from A. (C.) neolimosaesp. nov. and estimated genetic distances from 10 other Alloptes species based on comparisons of COI sequences.

Alaudicola eremophila sp. n. is very similar to A. bilobatus (Robin, 1877) from the Eurasian Skylark, Alauda arvensis Linnaeus, in having the opisthosomal lobes short with a truncated or bluntly rounded posterior margin (Gaud & Atyeo 1996; Mironov 1996). Alaudicola eremophila differs from A. bilobatus by the following features: in males, the lateral margins of the terminal cleft are distinctly divergent, the terminal cleft is shaped as an equilateral triangle; in females, the secondary spermaducts are 18–20 long, setae ps3 situated approximately at the level of the anterior one third of the anal slit. In males of A. bilobatus, the lateral margins of the terminal cleft are almost parallel, the whole terminal cleft is nearly U-shaped, and 8–10 wide at midlength; in females, the secondary spermaducts are 25–30 long, and setae ps3 are situated approximately at the midlength of the anal slit or slightly posterior. Etymology. The specific epithet is taken from the generic name of the type host and is a noun in apposition. Remark. The new species described above was previously reported from E. alpestris in Canada (Galloway et al. 2014: 170) under the name A. bilobatus., Published as part of Mironov, Sergey V. & Galloway, Terry D., 2021, Feather mites of the subfamily Pterodectinae (Acariformes: Proctophyllodidae) from passerines and kingfishers in Canada, pp. 1-55 in Zootaxa 5016 (1) on pages 38-42, DOI: 10.11646/zootaxa.5016.1.1, http://zenodo.org/record/5221702, {"references":["Robin, C. & Megnin, P.

Genus Alaudicola Mironov, 1996 Type species: Proctophyllodes (Pterodectes) bilobatus Robin, 1877, by original designation. Diagnosis. Both sexes. Moderately elongated pterodectines. Full set of hysteronosomal setae. Full set of leg setae occurring in pterodectines, or setae sR III can be absent. Setae c2 on humeral shields or on striated tegument. Setae c3 spiculiform. Male. Opisthosomal lobes of moderate length, 1.5–2 times longer than wide at base, rounded, truncated or slightly attenuate apically, apices with or without small membranous denticles. Setae ps3 lateral or posterolateral to adanal suckers. Bases of opisthosomal lobes crossed by opisthoventral shields forming translobar apodemes and bearing setae ps3. Ventral surface of opisthosomal lobes distally without sclerotization. Setae h3 spiculiform. Aedeagus sword-shaped, not extending beyond lobar apices. Genital papillae at level of genital arch base and usually strongly reduced. Female. Setae ps2, ps3 arranged in wide trapezoid, always filiform; setae ps2 can be absent. Macrosetae h2 long whip-shaped, gradually attenuate to filiform apices. Remark. In contrast to the previous three genera, Alaudicola belongs to the Montesauria generic complex (Mironov 2009; Mironov et al. 2010, 2012), representatives of which were previously known from the Old World. To date, the genus Alaudicola has included four species associated with oscine passerines; three of them are specific to larks (Alaudidae) and one is known from the Western Black-eared Wheatear, Oenanthe hispanica (Linnaeus, 1758) (Muscicapidae) (Gaud & Atyeo 1996; Mironov 1996, 2006). Included species: Alaudicola bilobatus (Robin, 1877), A. bureschi (Vassilev, 1958), A. eremophila sp. n., A. rosickyi (Cerny, 1963), and A. holothyra (Gaud, 1952)., Published as part of Mironov, Sergey V. & Galloway, Terry D., 2021, Feather mites of the subfamily Pterodectinae (Acariformes: Proctophyllodidae) from passerines and kingfishers in Canada, pp. 1-55 in Zootaxa 5016 (1) on pages 37-38, DOI: 10.11646/zootaxa.5016.1.1, http://zenodo.org/record/5221702, {"references":["Robin, C. & Megnin, P.

Glesoconomorphus ekaterinaesp. nov. (Coleoptera, Mycteridae), representing the first ever fossil species of Coleoptera from the Volyn Region of Ukraine and the first mycterid from late Eocene Rovno amber, is described and illustrated. A key to species of the fossil mycterid genus Glesoconomorphus Alekseev, Pollock & Bukejs, 2019 is presented. The systematic position of Glesoconomorphus within Eurypinae J. Thomson, 1860 is briefly discussed. The oldest finding of phoretic Winterschmidtiidae Oudemans, 1923 mites, found on the type specimen of the new beetle species, is reported.

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., Acarologia, 60, 878-891

A new species of acarid mite, Naiadacarus sidorchukae sp. n., is described from phoretic deutonymphs collected from a European spruce bark beetle, Ips typographus, pheromone trap in Western Siberia, Russia. Morphologically, the new species is very similar to the North American species, Naiadacarus fashingi , with the only diagnostic character being the shorter tibial solenidion φ II in the former species. Unlike some Naiadacarus species, which are truly aquatic, Naiadacarus sidorchukae probably does not inhabit fully aquatic habitats. This species and other presumably non-aquatic taxa, may represent the ancestral condition in the genus Naiadacarus , and, therefore are critical in studying land to water ecological transitions that have occurred in this mite genus. The monotypic genus Naiacus Nesbitt, 1990 is considered as a junior synonym of Naiadacarus Fashing, 1974 ( syn. n. ), with its type-species, Naiacus muertensis Nesbitt, 1990, recombined as Naiadacarus muertensis (Nesbitt, 1990), comb. n. A key to species of Naiadacarus of the world is provided

[types studied] Diagnosis. Adults are similar to those of the genus Schwiebea Oudemans, 1916, but the leg tarsi are long, longer than 3 times the basal width (less than 3 times as long as wide in Schwiebea); solenidia �� 1 I-II cylindrical, long and thin, not expanded at tip (clearly expanded at tip in Schwiebea); on tarsi I���II, ventral tarsal setae wa are distinctly separated from setae ra and la (closely associated in Schwiebea, except for S. estradai Fain & Ferrando, 1990).

In the original description of this mite, Hirundo rustica was declared as the type host of this species (Gaud 1957). This association is considered questionable and most likely this record was the result of contamination. Trouessartia piscicauda is common to the sand martin, R. riparia, on which it was recorded throughout its range, in Europe, Africa, South East Asia, and North America (Cuba) (Gaud 1957; Čern�� 1967; Santana 1976; Gaud & Atyeo 1986)., Published as part of Mironov, Sergey V. & Galloway, Terry D., 2019, Feather mites of the genus Trouessartia Canestrini (Acariformes: Trouessartiidae) from swallows (Passeriformes: Hirundinidae) in Canada, pp. 1-39 in Zootaxa 4568 (1) on pages 10-11, DOI: 10.11646/zootaxa.4568.1.1, http://zenodo.org/record/2599119, {"references":["Gaud, J.

Trouessartia petrochelidon sp. n. belongs to the minutipes species group and is very similar to T. quarta Gaud and Atyeo, 1987 in having sclerites rEpIIa with acute inner ends and epimerites IVa fused with the base of the genital apparatus in males, and the distal end of the primary spermaduct straight and the external copulatory tube absent in females. Trouessartia petrochelidon differs from T. quarta by the following features: in both sexes, the posterior part of the prodorsal shield bears a faint ornamentation of small lacunae; in males, the terminal lamellae are longer (20–25 µm) and the idiosoma length is 420–475 µm (Figs. 13A, 15E); in females, the proximal part of the primary spermaduct is regularly enlarged toward the head of spermatheca (Fig. 15H). In both sexes of T. quarta, the prodorsal shield lacks any distinct ornamentation; in males, the terminal lamellae are 16–18 µm long, and the idiosomal length is 390–410 µm; in females, the primary spermaduct is enlarged unequally, its part between the head of spermathecal and secondary spermaducts is 2 times wider than the part distal to the secondary spermaducts (Fig. 21D). Etymology. The specific epithet is taken from the generic name of the host and is a noun in apposition.

Trouessartia quarta was originally described from the barn swallow, Hirundo rustica, in South East Asia (Malaise, Thailand) (Gaud & Atyeo 1987). These authors noted that it does not occur on the same host individuals together with T. microcaudata Mironov, 1983, a species of the minutipes group widely distributed on this host in the Old World, from Europe to South East Asia (Mironov 1983, 1996; Gaud & Atyeo 1987). The latter authors suggested that T. quarta is restricted to the Indo-Malayan region and considered a single specimen of this mite found on a museum skin of H. rustica from Cuba as accidental contamination. Our study of samples from Canada and additional museum material shows that T. quarta is also widely distributed on H. rustica in the New World, from Canada to Argentina., Published as part of Mironov, Sergey V. & Galloway, Terry D., 2019, Feather mites of the genus Trouessartia Canestrini (Acariformes: Trouessartiidae) from swallows (Passeriformes: Hirundinidae) in Canada, pp. 1-39 in Zootaxa 4568 (1) on page 31, DOI: 10.11646/zootaxa.4568.1.1, http://zenodo.org/record/2599119, {"references":["Gaud, J. & Atyeo, W.

In both sexes of T. stelgidopteryx and T. bochkovi, the prodorsal shield is free from the scapular shields; in males, seta d of tarsus IV is situated in the proximal half of this segment, the pieces of lobar shield are connected at antero-median angles, and the length of the idiosoma is 380–470 µm; in females, setae h1 are lanceolate, the distal end of the primary spermaduct is straight, the external copulatory tube is short spine-like and situated on the free margin of the interlobar membrane. Etymology. The specific epithet is derived from crypto (L. hidden) and caudus (L. tail) and refers to hidden external copulatory duct in females.

The new species, Trouessartia ampulicaudata sp. n., belongs to the appendiculata species group (Gaud & Atyeo 1986), and is closest to T. appendiculata (Berlese, 1886) in having, in males, setae g situated at level of setae 4a, long setae h3 with a filiform apex, the terminal lamellae with attenuate apices, and in females, narrowly lanceolate setae h1, and a distinctly sclerotized external copulatory tube. Trouessartia ampulicaudata differs from T. appendiculata by the following features: in both sexes, setae c2 are longer (45–55 µm), in males, the bases of setae g are distinctly separated from each other, the rudimentary sclerites rEpIIa are roughly semi-ovate, and in females, the external copulatory tube is ampuliform and relatively short (23–32 µm), the head of the spermatheca has rounded spines and lacks a collar, and the proximal part of the primary spermaduct is enlarged toward the head of the spermatheca. In both sexes of T. appendiculata, setae c2 are 38–42 µm long, in males, the bases of setae g are almost touching, the rudimentary sclerites rEpIIa have an attenuate posterior extension (shaped as an inverted teardrop); in females, the external copulatory tube is finger-shaped, slightly curved, and about 30–40 µm long, the head of the spermatheca has acute spines and a short collar, and the proximal part of the primary spermaduct does not have any enlargements. Etymology. The specific epithet refers to the ampule-shaped external copulatory tube in females.

Material examined: 7 males and 11 females (ZISP 7458–7475) from Hirundo rustica Linnaeus, 1758 (Passeriformes: Hirundinidae), CANADA, Manitoba, Winnipeg, 7 June 1999, coll. T.D. Galloway. Trouessartia appendiculata was originally described from the sand martin, Riparia riparia (Linnaeus) (Berlese 1886). However, this record was probably the result of accidental contamination or incorrect host identification, because this mite species is specific to swallows of the genus Hirundo (Santana 1976; Gaud & Atyeo 1986). At the same time, the appendiculata species group is represented on R. riparia by T. piscicauda Gaud, 1957 (see below), which is unmistakably different from T. appendiculata by the structure of the terminal lamellae in males (Figs. 16A versus D). Trouessartia appendiculata was reported from H. rustica almost worldwide, in Europe, Africa, South East Asia and North America (Canada, Cuba), and also from H. smithi (Leach) in Cameroon (Gaud & Till 1961; Černý 1967; Santana, 1976; Gaud & Atyeo 1986; Galloway et al. 2014). The reports of this mite from Cecropis senegalensis (Linnaeus) and Psalidoprocne pristoptera petiti Sharpe & Bouvier in Cameroon (Gaud 1957; Gaud & Mouchet 1958) were proven to be misidentifications (Gaud & Atyeo 1986); the reports from Pseudhirundo griseopyga (Sundevall) in Zair (Gaud & Atyeo 1986) and Petrochelidon pyrrhonota (Vieillot) in the Wrangel Island, Russia (Dubinin 1952), also are highly probable misidentifications., Published as part of Mironov, Sergey V. & Galloway, Terry D., 2019, Feather mites of the genus Trouessartia Canestrini (Acariformes: Trouessartiidae) from swallows (Passeriformes: Hirundinidae) in Canada, pp. 1-39 in Zootaxa 4568 (1) on page 10, DOI: 10.11646/zootaxa.4568.1.1, http://zenodo.org/record/2599119, {"references":["Canestrini, G.

Material examined: 1 male (ZISP 14014) Hirundo rustica erythrogaster (Boddaert, 1783) (Passeriformes: Hirundinidae), ARGENTINA, Corrientes Province, Estancia Ricón de Luna, 10 November 1961, coll. W.H. Partridge; 1 male, 6 females (ZISP 14 005–14 011), same host species, PANAMA, Coclé Province, Agua Dulce, 12 September 1925, coll. R.R. Benson. Trouessartia crucifera is the only species constituting the crucifera group. This species was originally described from Hirundo rustica Linnaeus in Morocco (Gaud 1957). Further, it was found on this host in Europe, Africa and Central America (Cuba) and also on related hirundinid species, H. dimidiata Sundevall, H. lucida Hartlaub and Cecropis abyssinica (Guérin-Méneville) in Africa and on C. daurica (Laxmann) in Thailand (Černý 1967; Mironov 1996; Gaud & Atyeo 1986). On Hirundo species, this mite was often found together with T. appendiculata and T. microcaudata (Gaud & Atyeo 1986; Mironov 1996). Among Trouessartia species associated with hirundinids, T. crucifera is characterized by the unique structure of the genital apparatus which is flanked laterally by the paragenital apodemes, and the opisthosomal lobes being separated by a long, narrow terminal cleft. Gaud and Atyeo (1986) suggested this species is close to the appendiculata group. In our opinion, the presence of long and distally unfused opisthosomal lobes in males (Fig. 17D) is evidence that this species is more likely related to the stelgidopteryx group. We did not find Trouessartia crucifera infesting swallows from Canada, but considering its wide distribution in the Old World and also the presence of this species on H. r. erythrogaster in South America, it is likely this mite occurs in North America as well., Published as part of Mironov, Sergey V. & Galloway, Terry D., 2019, Feather mites of the genus Trouessartia Canestrini (Acariformes: Trouessartiidae) from swallows (Passeriformes: Hirundinidae) in Canada, pp. 1-39 in Zootaxa 4568 (1) on page 24, DOI: 10.11646/zootaxa.4568.1.1, http://zenodo.org/record/2599119, {"references":["Gaud, J.

In the analyses, key, and descriptions, the idiosomal chaetotaxy follows Griffiths et al. (1990) with modifications of Norton (1998) for coxal setae. The leg chaetotaxy follows Grandjean (1939). All measurements are given in micrometers (��m) and were taken as follows: body length = total length from the anterior extremity of the palps to the posterior border of the body, including the lobar membranes in males; body width = width at the level of setae cp; length of dorsal shields = maximum length, measured along the median line of the shields; length of male opisthosomal lobes = measured from the anterior edge of the opisthosomal cleft to the posterior end of the lobe; length of the posterior legs = length from the most basal point of the trochanter to the apex of the tarsus, excluding pretarsus. Drawings were made with a Leica microscope equipped with differential interference contrast (Nomarski) optics and a camera lucida. Fine mite structures (mites from Atelerix albiventris, ZISP AVB 14-0505-004) were examined with a scanning electron microscope Quanta 250. Mites were put in 96% ethanol for 24 hours, transferred to hexamethyldisilazane for 10 minutes, and then dried and sputtered with platinum. DNA amplification, sequencing, and alignment. We sequenced individual specimens of Caparinia from Atelerix albiventris and Erinaceus europaeus for 6 genes: two nuclear ribosomal RNA genes, 18S and 28S rDNA; three nuclear protein-coding genes: elongation factor 1alpha100E (EF1-��), signal recognition particle protein 54k (SRP54), Hsc70-5 heat shock protein cognate 5 (HSP70); and one mitochondrial protein-coding gene (CO1). CO1 was sequenced from 14 specimens for Caparinia ex Atelerix albiventris (all were identical) and 2 specimens of Caparinia tripilis ex Erinaceus europaeus. Previously published amplification and sequencing protocols were used (Bochkov et al., 2014; Klimov & OConnor, 2008, 2013; Knowles & Klimov, 2011). GenBank accession numbers are as follows: MG766225 - MG766259, MG766261 - MG766269 (Table 1). The sequence of 18S of Caparinia from Erinaceus europaeus (MG766260) was identified as a gregarine (an endoparasitic protozoan) and, therefore, was excluded from further analyses. Domain D4 of 28S rDNA was also excluded because our standard protocol TABLE 1. Collection data and GenBank accession numbers for select taxa of the scab mite family Psoroptidae (id=unique numbers for DNA extraction vouchers; field number = lot-based museum UMMZ accession numbers for vouchers and co-vouchers). *Gregarine sequence amplified, GenBank accession number MG766260. produced superimposed sequences. Sequences of rDNA were aligned in Mesquite ver. 3.31 (Maddison & Maddison, 2016) using a previously established secondary structure model (Klimov & OConnor, 2008); alignment of other loci was unambiguous. Voucher and co-voucher mite specimens are deposited in the University of Michigan Museum of Zoology, Ann Arbor, Michigan under the following accession numbers: BMOC 13-0508-003 (AD1647): Caparinia ictonyctis, ex Atelerix albiventris; BMOC 16-0825-012 (AD2034), BMOC 16-0825-013 (AD2035): Caparinia tripilis, ex Erinaceus europaeus.

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.

Four new species of the feather mite genus Anhemialges (Astigmata: Analgidae) are described from passeriform birds in China: A. lioparus sp. nov. from the Golden–breasted Fulvetta Lioparus chrysotis (Passeriformes, Paradoxornithidae); A. aegithalos sp. nov. from the Black–throated Tit Aegithalos concinnus (Passeriformes, Aegithalidae); A. seicercus sp. nov. from the Golden–spectacled Warbler Seicercus burkii (Passeriformes, Phylloscopidae); and A. zosterops sp. nov. from the Oriental White–eye Zosterops palpebrosus (Passeriformes, Zosteropidae).

The specific epithet is derived from the generic name of the host. Differential diagnosis. The new species is closest to A. mironovi Kolarova, 2010 from Locustella luscinioides (Passeriformes: Locustellidae) in that the males of both species have subtegumental sclerotization on the hysteronotal shield and long subtriangular incisions of the interlobar membrane, extending beyond the midlength of the terminal cleft. The new species differs from A. mironovi by the following features: in males of A. zosterops, the subtegumental sclerotization on the hysteronotal shield is bow-shaped, setae ps1 are about 3 times longer than the distance between them, and the wide adanal membranes stretch from the adanal shield to the level of tibia–tarsus IV articulation. In A. mironovi, the subtegumental sclerotization on the hysteronotal shield is crescent-shaped, setae ps1 are not longer than 1.5 times the distance between them, and the adanal membranes are narrow. Females of A. zosterops and A. mironovi differ in the length of setae e2: in females of the new species, the setae e2 are minute and about quarter length of the distance between them, in A. mironovi the setae e2 slightly longer, about half length of the distance between them. Remark. In males, the membranous enlargement in the medial part of setae h 3 may have become rolled-up, thus affecting the measurement of its width.

The new species is closely related to A. bakeri Dabert et al., 2010 from Phylloscopus collybita (Passeriformes: Phylloscopidae) because the males of both species have macrosetae h3 setiform, without a flattened enlargement in the medial part, and having paired adanal shields and setae ps1 about 1.5 times longer than the distance between them. The new species differs from A. bakeri by the following features: in males of the new species, each of the paragenital apodemes divide into two parts; setae w and s of tarsus III are shaped as thick spines; the adanal shields are separated from the gastral shields; and the incision in the interlobar membrane goes beyond the midlength of the terminal cleft. Males of A. bakeri do not have paragenital apodemes, setae w and s on tarsi III are hair���like, the adanal shields are fused anteriorly with the posterior margin of the corresponding part of the gastral shields, and the incision in the interlobar membrane is at about the midlength of the terminal cleft. Females of A. seicercus and A. bakeri differ in the length of the idiosoma and the existence of setae e1: A. seicercus is 392���398 long and lacking setae e1, A. bakeri is 485���496 long, and has minute setae e1., Published as part of Chang, Hui-Qun, Wang, Zi-Ying & Liu, Huai, 2018, Four new feather mite species of the genus Anhemialges Gaud, 1958 (Astigmata: Analgidae) from China, pp. 251-265 in Zootaxa 4531 (2) on pages 260-263, DOI: 10.11646/zootaxa.4531.2.6, http://zenodo.org/record/2614604, {"references":["Dabert, J., Nattress, B. & Labrzycka, A.

Genus Strelkoviacarus Dubinin, 1953 Type species: Pteronyssus quadratus Haller, 1882, by original designation The genus Strelkoviacarus was originally established in the family Epidermoptidae by Dubinin (1953). Fain (1965) excluded Strelkoviacarus from this family and regarded it as incertae sedis. Gaud & Atyeo (1982) placed this genus in the family Analgidae, subfamily Anomalginae. Females of Strelkoviacarus are the only mites of the family Analgidae detected in phoretic association with louse flies (Diptera: Hippoboscidae) specialized to birds that explains polyxenic host associations and almost cosmopolitan distribution of their species, since hippoboscids can carry these mites to long distances and transfer between phylogenetically distant hosts like Coraciiformes, Piciformes, Galliformes, Strigiformes and Passeriformes (Mironov 1996; Philips 2000; Mironov et al. 2010; Fuentes-Castillo et al. 2016). Up to date, four Strelkoviacarus species have been described: S. critesi Spory, 1965, S. holoaspis Mironov et al., 2010, S. integer (Trouessart & Neumann, 1888) and S. quadratus (Haller, 1882) (Trouessart & Neumann 1888; Spory 1965; Hill et al. 1967; Gaud & Atyeo 1996; Mironov et al. 2010)., Published as part of Pedroso, Luiz Gustavo A. & Hernandes, Fabio Akashi, 2018, Two new feather mite species of the family Analgidae (Acariformes: Analgoidea) from the Rufous-collared Sparrow Zonotrichia capensis (M��ller, 1776) (Passeriformes: Passerellidae), pp. 233-244 in Zootaxa 4461 (2) on pages 238-239, DOI: 10.11646/zootaxa.4461.2.4, http://zenodo.org/record/1459932, {"references":["Dubinin, V.

Genus Analges Nitzsch, 1818 Type species: Acarus passerinus Linnaeus, 1758, by subsequent designation (Von Heyden, 1826). Analges is the oldest feather mite genus with a quite complicate taxonomy. The main reason is that males of this genus exhibit strong polymorphism, especially in the structure of legs III, and only the heteromorphic males can be used for reliable morphological species identification (Gaud 1973; Mironov 1985). To date, approximately 55 species have been described, many of which badly need a redescription (Gaud 1973; Mironov 1985; Sohn 1995; Mironov 1996; Mironov & Kopij 1996; Su et al. 2013). The genus Analges is presently divided into three subgenera, Analges s. str., Analgopsis Trouessart, 1919 and Plesialges Trouessart, 1919. The two latter subgenera were originally established as full genera and curiously declared as new taxa twice, in the works of Trouessart (1919) and Trouessart & Berlese (1919). Gaud (1973) included Analgopsis into the genus Analges as a subgenus but did not outline clear diagnostic features for its subgenera. Mironov (1985) properly indicated differences between them: males of Analges s. str. lack a finger-like process on the inner margin of tarsus III, whereas those of Analgopsis have a prominent finger-like process bearing seta w. The monotypic Plesialges was included into Analges as a subgenus by Gaud & Atyeo (1996) but this taxon still lacks a reliable modern diagnosis that reinforces the appeal to revise the genus.

Primary spermaduct with ampuliform enlargement at spermathecal head, secondary spermaducts short (Fig. 2C). Femur II with small lateral apophysis. Differential diagnosis. Analges (A.) ticotico sp. nov. is most similar to A. (A.) opistostriatus Mironov, 1985, described from the Eurasian reed warbler Acrocephalus scirpaceus (Hermann, 1804) (Acrocephalidae). In addition to their general similarity in having a relatively narrow body shape, heteromorphic males of both species have moderately-sized spines on the posterior margin of the prodorsal shield, the rectangular terminal lamella, and the anterior margin of the adanal shield strongly convex. Heteromorphic males of A. (A.) ticotico differ from those of A. opistostriatus in having the anterior margin of hysteronotal shield straight or slightly sinuous, setae d1 inserted at the level of subhumeral setae c3, the posterior branches of adanal shield reaching the end of opisthosoma; and three small blunt spines on the inner margin of the femur III. In A. (A.) opistostriatus, the anterior margin of the hysteronotal shield is concave; setae d1 are situated at the level of humeral setae cp; the posterior branches of the adanal shield do not reach the end of the opisthosoma; and the femur III has two blunt spines. Heteromorphic males of A. ticotico also resemble generally A. (A.) odontothyrus Gaud, 1973, especially by the legs III lacking large spine-like projections, and by the adanal shield reaching the end of opisthosoma. Analges (A.) ticotico differs from the latter by the convex anterior margin of the adanal shield (vs. concave in A. odontothyrus) and by dorsal setae e1 inserted anterior to the levels of the hysteronotal gland openings gl and cupules im (vs. at the same level or posterior to those glands in A. odontothyrus). Since females of this genus are seldom illustrated, comparing and distinguishing of them is quite difficult at present. Etymology.

The new species, Nycteridocaulus leptopogoni Mironov sp. n., is most similar to N. tyranni Atyeo, 1966 from Contopus pertinax Cabanis and Heine (Tyrannidae) from Mexico in having numerous large circular lacunae on the dorsal shields in both sexes, and short terminal lamellae of rectangular form and thick L-shaped adanal shields in males. Nycteridocaulus leptopogoni differs from the latter species as follows: in males, the pregenital apodemes are absent, setae ps3 are situated on the adanal shields and the terminal cleft extends to the level of setae h2; in females, the terminal cleft is narrow and nearly 5 times longer than wide, and setae h2 are distinctly shorter than terminal appendages. In males of N. tyrrani, the pregenital apodemes are represented by small sclerites of irregular form situated anterior to setae 4a, setae ps3 are situated off the adanal shields, and the terminal cleft barely extends to the level of setae h3; in females, the terminal cleft is 1.5 – 2 times longer than wide at midlength, and macrosetae h2 are nearly 2 times longer than the terminal appendages. Etymology. The specific epithet is derived from the generic name of the type host and is a noun in the genitive case.

The specific epithet is derived from the generic name of the type host and is a noun in the genitive case., Published as part of Mironov, Sergey V., Ehrnsberger, Rainer & Dabert, Jacek, 2017, Feather mites of the genera Dubininia and Cacatualges (Acari: Xolalgidae) associated with parrots (Aves: Psittaciformes) of the Old World, pp. 451-490 in Zootaxa 4272 (4) on pages 477-479, DOI: 10.11646/zootaxa.4272.4.1, http://zenodo.org/record/800966

Proctophyllodes thraupis Atyeo and Braasch, 1966 Proctophyllodes thraupis Atyeo and Braasch 1966: 134, figs. 117, 118. Material examined. 6 males and 9 females (ZISP 6449–6463) from Tangara icterocephala (Bonaparte, 1851) (Thraupidae), COSTA RICA, Tapantí National Park, Sector Tapantí, Cordillera de Talamanca Mts., 09°46'N, 83°47′W, 7 August 2009, collectors I. Literak, O. Sychra and M. Capek; 3 males and 5 females (ZISP 6523–6530), same collection data, except date, 8 August 2009. This species was previously recorded by Atyeo and Braasch (1966) from two species of tanagers (Thraupidae) in Mexico and Belize: Chlorophanes spiza (Linnaeus) from Belize and Mexico and Thraupis abbas (Deppe) (type host) from Mexico. These authors also reported this mite from Chlorospingus flavopectus ophthalmicus (Du Bus de Gisignies) (Emberizidae) from Mexico and from Euphonia affinis (Lesson), E. hirundinacea Bonaparte (mentioned as T. lauta Bangs and Penard), and E. musica (Gmelin, JF) (Fringillidae) from Belize and Mexico. Natural associations of Proctophyllodes thraupis with hosts other than thraupids look questionable. These findings could be the result of accidental contaminations, since Atyeo and Braasch collected most of their materials from dry museum skins. Besides, mite specimens found by these authors on euphonias could potentially represent another species, P. euphoniae or P. vesicularis, described above from Euphonia species., Published as part of Mironov, Sergey V., Literak, Ivan, Sychra, Oldrich & Capek, Miroslav, 2017, Feather mites of the subfamily Proctophyllodinae (Acari: Proctophyllodidae) from passerines (Aves: Passeriformes) in Costa Rica, pp. 1-105 in Zootaxa 4297 (1) on page 94, DOI: 10.11646/zootaxa.4297.1.1, http://zenodo.org/record/840212, {"references":["Atyeo, W.

Platyacarus dendrocolapti differs from P. sittasomi and P. dendrocinclae by the following features: in males, the genital organ is much shorter (14���18 ��m) and does not extend to the level of genital setae g; in females, the median extension on the posterior margin of the prodorsal shield is widely rounded and setae h3 are about 1/4���1/3 the length of the terminal appendages. In males of P. dendrocinclae and P. sittasomi, the genital organ is longer than 35 ��m and extends distinctly beyond the level of setae g; in females, the median extension on the posterior margin of the prodorsal shield is blunt-angular and setae h3 are about 1/5 the length of the terminal appendages. Additionally, males of P. dendrocolapti differ from those P. sittasomi in having the antero-lateral pieces of the adanal shields reniform or ovate (vs. narrow, bow-shaped in P. sittasomi) and the presence of paragenital apodemes (vs. absence); and females are distinguished by the lack of lacunae on the hysteronotal shield (vs. presence).

Homeomorphic males (legs I not enlarged and apodemes I free) not found. Differential diagnosis. Similar to Hughesiella; see key to genera below for the diagnostic characters (couplet 14). Can be distinguished from all pyroglyphids by the presence of flattened, medium-sized dorsocentral setae (si, c 1, d 1, e 1) (i.e., exceeding half the distance between respective paired setae). In other pyroglyphids, these setae are distinctly shorter. Etymology. The new genus is named for Dra. Edna Clara Tucci (Instituto Biol��gico, State of S��o Paulo, Brazil) in recognizing her research on parasitic arthropods attacking Brazilian poultry. The second part of the generic name is derived from glyphus (from the Greek verb �������������to carve, cut out with a knife, engrave), which is commonly used to form compound names for Astigmata. The gender is masculine., Published as part of Horn, Tamara Bianca, Ferla, J��lia Jantsch, K��rbes, J��lia Horn, Granich, Juliana, Oconnor, Barry, Klimov, Pavel & Ferla, Noeli Juarez, 2017, Two new genera of pyroglyphid mites, Tuccioglyphus and Marioglyphus, with a key to genera of the World (Acari: Pyroglyphidae), pp. 301-320 in Zootaxa 4244 (3) on pages 303-304, DOI: 10.11646/zootaxa.4244.3.1, http://zenodo.org/record/426092

Legs III and IV subequal in size; segments without modifications; solenidion �� of tibia IV equal to or slightly longer than �� of tibia III. Hosts: Tyrannidae. Remarks. The genus currently included four species associated with Tyrannidae (Atyeo 1967a, 1969; Hernandes et al. 2007; Mironov & Gonz��lez-Acu��a 2009). Atyeo (1967a) originally erected the genus Anisophyllodes based on a single species, Anisophyllodes pipromorphae Atyeo, 1967, which was described only from males. Establishing the genus, this author erroneously indicated that idiosomal setae e1 are absent in A. pipromorphae, and this feature was included in the diagnosis of the genus. Actually these setae in A. pipromorphae are present but are very close to the strongly sclerotized lateral margins of the hysteronotal shield, and for this reason they were simply missed. In all subsequently described species these setae are clearly visible (Atyeo 1969; Mironov & Gonz��lez-Acu��a 2009). Below we describe one new species, describe for the first time a female of A. pipromorphae and provide a new key to species. Anisophyllodes pipromorphae is a unique species in the genus Anisophyllodes in having two uncommon features. First, this species exhibits male dimorphism (hetero- and homeomorphs), which is quite rare within the subfamily Proctophyllodinae. Second, females of A. pipromorphae are unique among proctophyllodines because they have the epigynum fused with epimerites IIIa, as it is in all representatives of the subfamily Pterodectinae., Published as part of Mironov, Sergey V., Literak, Ivan, Sychra, Oldrich & Capek, Miroslav, 2017, Feather mites of the subfamily Proctophyllodinae (Acari: Proctophyllodidae) from passerines (Aves: Passeriformes) in Costa Rica, pp. 1-105 in Zootaxa 4297 (1) on page 66, DOI: 10.11646/zootaxa.4297.1.1, http://zenodo.org/record/840212, {"references":["Atyeo, W.
