Two new feather mites of the genus Trouessartia Canestrini, 1899 (Acariformes: Trouessartiidae) from tyrant flycatchers (Passeriformes: Tyrannidae) in Argentina

Two new species of the feather mite genus Trouessartia (Analgoidea: Trouessartiidae) are described from tyrant flycatchers (Tyrannidae) in Argentina: Trouessartia salvadori sp. nov. from the White-crested Tyrannulet Serpophaga subcristata (Vieillot) and T. gonzalezacunai sp. nov. from the Vermilion Flycatcher Pyrocephalus rubinus (Boddaert). Trouessartia salvadori sp. nov. is close to T. longiducta Hernandes et Valim, 2015 and most clearly differs from the latter in having, in males, the genital apparatus with wedge-shaped hyaline extensions and the anterior genital papillae situated more distant from the midline than posterior ones, and in females, setae h1 not extending beyond the margin of the interlobar membrane, and the posterior part of the hysteronotal shield bearing well outlined ovate lacunae except in the narrow median area. Trouessartia gonzalezacunai sp. nov. is similar to T. savanae Hernandes, 2014, but is distinguished from that species in having, in males, the terminal lamellae shaped as a fishtail, the epiandrum shaped as a goblet, the apophyses of adanal apodemes represented by thick spine-like tubercles, and in females, setae h1 minute spiculiform about 10 long, and the external copulatory tube shaped as a small rounded tubercle near the margin of interlobar membrane.

TWO NEW SPECIES OF THE FEATHER MITE GENUS TROUESSARTIA (ACARIFORMES: TROUESSARTIIDAE) FROM ROBINS AND CHATS (PASSERIFORMES: MUSCICAPIDAE) IN THE RUSSIAN FAR EAST

Two new species of the feather mite genus Trouessartia (Analgoidea: Trouessartiidae) are described from passerine birds in Primorsky Krai (Russian Far East): Trouessartia calliope sp. n. from the Siberian Rubythroat Calliope calliope (Linnaeus) and T. larvivorae sp. n. from the Rufous-tailed Robin Larvivora sibilans (Swinhoe) (Passeriformes: Muscicapidae: Saxicolinae). Both new species are close to T. swidwiensis Jablonska, 1968 associated with nightingales of the genus Luscinia (Linnaeus) (Muscicapidae) in having the prohysteronotal and lobar parts of the hysteronotal shield not separated in males and in having setae h1 situated on large ovate non-sclerotized areas and in the absence of the external copulatory tube in females.

A NEW SPECIES OF THE FEATHER MITE GENUS TROUESSARTIA (ACARIFORMES: TROUESSARTIIDAE) FROM THE TRISTRAM’S BUNTING EMBERIZA TRISTRAMI (PASSERIFORMES: EMBERIZIDAE) IN THE RUSSIAN FAR EAST

A new feather mite species, Trouessartia emberizae sp. n., is described from the Tristram’s Bunting, Emberiza tristrami Swinhoe (Passeriformes: Emberizidae) in the Primorye Territory (Russian Far East). The new species is close to T. jedliczkai (Zimmermann) and T. motacillae Dubinin, associated with wagtails (Motacillidae: Motacilla) and most clearly differs from them in the following features: in males, the hysteronotal shield is entire and the genital apparatus is narrow, parallel-sided and strongly convex dorsally; in females, the external copulatory tube is stylet-like and extends beyond the level of setae h3, and the head of the spermatheca has a short smooth collar. This is the first description of a Trouessartia species from a host of the family of buntings (Emberizidae).

TWO NEW FEATHER MITES OF THE GENUS PROCTOPHYLLODES ROBIN (ACARIFORMES: PROCTOPHYLLODIDAE) ASSOCIATED WITH PASSERINES (AVES: PASSERIFORMES) IN THE RUSSIAN FAR EAST

Two new species of the feather mite genus Proctophyllodes (Proctophyllodidae: Proctophyllodinae) are described from passerines in the Primorye Territory, Russia: Proctophyllodes bochkovi sp. n. from the blue-and-white flycatcher Cyanoptila cyanomelana (Temminck) (Muscicapidae) and P. cyanopicae sp. n. from the azure-winged magpie Cyanopica cyanus (Pallas) (Corvidae). Proctophyllodes bochkovi belongs to the caulifer species group. It differs from the most similar species, P. cotyledon Trouessart, 1899, in having the genital arch not extending to the level of epimerites IIIa, the terminal lamellae symmetrical with pennate venation and by the absence of the paragenital apodemes in males, and in having a longer lobar region (78–88 μm) in females. Proctophyllodes cyanopicae belongs to the musicus group and is readily distinguished from the most similar species, P. picae (Koch, 1841), in having the hysteronotal shield with well pronounced circular lacunae, and setae g situated closer to the level of setae ps3 than to the genital arch tips in males, and in having the terminal cleft shaped as a longitudinal rectangle 50–55 μm long in females.

Two new species of the feather mite genus Pteroherpus Gaud, 1981 (Analgoidea, Pteronyssidae) from China

Two new pteronyssid feather mite species are described from passeriform birds in China: Pteroherpus pomatorhinae sp. nov. from the Streak-breasted Scimitar-babbler Pomatorhinus ruficollis Hodgson (Passeriformes, Timaliidae), and Pteroherpus chinensis sp. nov. from the Collared Finchbill Spizixos semitorques Swinhoe (Passeriformes, Pycnonotidae). Pteroherpus pomatorhinae sp. nov. belongs to the diploplax species group. The males of Pteroherpus pomatorhinae sp. nov. have the prodorsal shield elongated, the opisthosoma narrowed to posterior end, the opisthosomal lobes slightly elongated, and two pairs of small additional sclerites (one dorsally, between prodorsal and hysteronotal shield, and one ventrally posterior to genital apparatus). The females of Pteroherpus pomatorhinae sp. nov. have a pair of anterior hysteronotal sclerites, a central sclerite, a pair of lateral opisthosomal sclerites partially split into lateral and inner fragments and a pair of pygidial sclerites. The central sclerite has almost parallel lateral margins and concave posterior margin, and the posterior ends of the fragments of opisthosomal shields are connected by a thick bridge. Pteroherpus chinensis sp. nov. belongs to the hoplophorus species group. The males of Pteroherpus chinensis sp. nov. have prodorsal shield slightly longer than wide, the opisthosoma moderately narrowed to posterior end, the opisthosomal lobes wide and short and the adanal shield with irregular form. The females of Pteroherpus chinensis sp. nov. have the anterior hysteronotal sclerite fused with the prodorsal shield into a complex shield, a central sclerite, a pair of lateral opisthosomal sclerites and a pair of pygidial sclerites. The central sclerite is well delimited, and shaped as a longitudinal plate, slightly narrower posteriorly, with slightly convex anterior margin, concave lateral margins, and strongly convex posterior end.

Two new feather mite species of the genus Montesauria Oudemans (Analgoidea: Proctophyllodidae) from thrushes (Passeriformes: Turdidae) in the Indian Subcontinent

Two new feather mite species of the genus Montesauria Oudemans, 1905, collected from thrushes (Turdidae) in India, are described: Montesauria hernandesi sp. n. from Turdus dissimilis Blyth, 1847 and M. caerulea sp. n. from Myophonus caeruleus (Scopoli, 1786). Both species belong to the merulae species group, being morphologically closest to other two species of the genus, previously described from birds of the family Turdidae in Asia (Japan): M. sibirica Kuroki, Nagahori and Mironov, 2006 and M. aurea Kuroki, Nagahori and Mironov, 2006, respectively. The new species most clearly differ from those described in Japan by the dorsal shield ornamentation. In both sexes of M. hernandesi sp. n., the ornamentation of the prodorsal and hysteronotal shields is represented by round and ovate lacunae, and the ornamentation of the lobar shield of females has few ovate lacunae. In both sexes of M. caerulea sp. n., the ornamentation of the hysteronotal shield is very particular, with large and almost round lacunae in the anterior half and small ovate lacunae in the posterior half.

A new feather mite species of the genus Trouessartia Canestrini, 1899 (Acarina, Trouessartiidae) – an integrative description (morphology and DNA barcoding data)

A new species of the feather mite genusTrouessartia(Trouessartiidae) is described from the Large NiltavaNiltavagrandis(Blyth) (Passeriformes, Muscicapidae) in Northeast India (Meghalaya, Jaintia Hills, Shnongrim village).TrouessartianiltavaeConstantinescu,sp. n.is morphologically closely related (no phylogenetic meaning) toT.bulligeraGaud, 1968 fromClytorhynchushamlini(Mayr) (Passeriformes: Monarchidae), sharing in males a unique character within the genus, by having setaeeon legs IV hemispheroid, with spine-shaped apex. Males of the new species have the prodorsal shield without ornamentation, the prohysteronotal shield and lobar shield connected, and the terminal cleft parallel sided. Females have the posterior half of the hysteronotal shield ornamented with large ovate lacunae in central area and small elliptical lacunae marginally. To the morphological description of this new feather mite species we added sequence data on the mitochondrial cytochrome c oxidase subunit I gene fragment (COI). The phylogenetic relationships betweenTrouessartiaspecies are briefly discussed.

Two new feather mite species of the family Analgidae (Acariformes: Analgoidea) from the Rufous-collared Sparrow Zonotrichia capensis (Müller, 1776 (Passeriformes: Passerellidae)

Two new feather mite species of the family Analgidae are described from the Rufous-collared Sparrow, Zonotrichia capensis (Müller, 1776) (Passeriformes: Passerellidae), from Brazil: Analges ticotico sp. nov. (Analginae) and Strelkoviacarus brasiliensis sp. nov. (Anomalginae). Analges ticotico sp. nov. is characterized by the heteromorphic males having three short and rounded spines on the inner margin of femur III, the anterior margin of adanal shield convex, the hysteronotal shield with the anterior margin sinuous, and the terminal lamella rectangular. Strelkoviacarus brasiliensis sp. nov. is characterized by the anterior ends of the adanal shields being convergent and encompassing the bases of setae ps3 in males, and by the strongly convex median extension of the prodorsal shield and short dorsal setae vi, c2, d2 and e2 in females. These species represent the first records of corresponding feather mite genera in Brazil.

Two new species of feather mites (Acarina: Psoroptidia) from the Oriental Magpie-Robin, Copsychus saularis (Passeriformes: Muscicapidae)

Two new feather mite species from the bird host Copsychus saularis (Linnaeus) collected in Indonesia (Kalimantan) are described: Dolichodectes latilobus n. sp. (Proctophyllodidae, Pterodectinae), and Trouessartia saularis n. sp. (Trouessartiidae). The new species, Dolichodectes latilobus, has the following distinctive characters: in males, the opisthosomal lobes are widened in the posterior half; the opisthoventral shields are fused, forming a single shield that covers ventrally the posterior quarter of the body; legs I have longitudinal crest-like processes ; and setae ra on these legs are spiculiform. In females of D. latilobus, the posterior margin of the hysteronotal shield has a deep median invagination, and epimerites II extend to the level of the anterior margin of epigynum. The males of T. saularis have the adanal apodemes with two narrow lateral membranes, and the females have the terminal cleft width smaller than the opisthosomal lobe width, and the collar of the spermatheca cover 1/2 from the length of secondary spermaduct.
