Two new species of the feather mite genus Trouessartia (Acari: Trouessartiidae) from Asia

Two new feather mite species of the genus Trouessartia Canestrini are described from birds captured in Meghalaya (India): Trouessartia longidenticulata Constantinescu sp. n. from Pycnonotus cafer (Linnaeus) (Passeriformes, Pycnonotidae) and Trouessartia dicruri Constantinescu sp. n. from Dicrurus aeneus (Vieillot) (Passeriformes, Dicruridae). In the genus Trouessartia, males of T. longidenticulata show a unique character state in having the lamellae of the opisthosomal lobes with long and sharp denticles. Both sexes of T. dicruri differ from closely related T. delicatula Gaud, 1952 by smaller body size (T. dicruri males are 420-452 long, females 500-532 long, vs. c. 575 and 595, respectively in T. delicatula); males have the adanal apodemes without apophyses and the terminal lamellae in a shape of a parallelogram (vs. the adanal apodemes have a pair of apophyses and the terminal lamellae are semi-ovate); the opisthosomal lobes do not touch each other at the inner margins (vs. the opisthosomal lobes touch each other at the inner margins, at the level of setae h3); in females, setae h1 are lanceolate (vs. spiculiform).

Two new species of the genus Trouessartia (Acari, Trouessartiidae) from laughingthrushes (Passeriformes, Leiothrichidae)

Abstract Two new feather mite species of the genus Trouessartia Canestrini are described from laughingthrushes (Passeriformes: Leiothrichidae) captured in Meghalaya (India): Trouessartia cyanouropterae sp. n. from Actinodura cyanouroptera (Hodgson) and Trouessartia alcippeae sp. n. from Alcippe nipalensis (Hodgson). It is the first time when species of the genus Trouessartia are described from leiothrichids.

Three new species of feather mite of the genus Proterothrix Gaud, 1968 (Analgoidea: Proctophyllodidae: Pterodectinae) from passerines in Meghalaya, North East India

Three new species of the feather mite subfamily Pterodectinae Park & Atyeo, 1971 are described from passerines of the family Muscicapidae Fleming and Leiothrichidae Swainson in India (Meghalaya, East Jaintia Hills District): Proterothrixdaberti n. sp. from the White-tailed Robin Cinclidium leucurum (Hodgson), P. khahnarensis n. sp. from the Blue Whistling-Thrush Myophonus caeruleus (Scopoli) (Passeriformes: Muscicapidae) and P. indica n. sp. from the Nepal Fulvetta Alcippe nipalensis (Hodgson) (Passeriformes: Leiothrichidae). P. daberti and P. khahnarensis belong to the megacaula species group and differ from one another (and from the third species belonging to the group) in having a distinct ornamentation of dorsal shields in both sexes: with small ovate and circular lacunae in P. daberti and with big ovate lacunae in P. khahnarensis. Proterothrix indica belongs to the paradoxornis species complex (wolffi species group) and differs from the other four species of the complex in having the lateral margins of prodorsal shield with incisions extending to bases of setae se in both sexes. Males of this species have opisthosomal lobes with acute apices.

Two new species of feather mites (Acarina: Psoroptidia) from the blue-throated blue flycatcher, Cyornis rubeculoides (Passeriformes: Muscicapidae)

ABSTRACT The paper describes two new species of feather mites collected from the blue-throated blue flycatcher Cyornis rubeculoides (Vigors) (Passeriformes: Muscicapidae) in India (Meghalaya): Trouessartia kharkhanensis Constantinescu et al. sp. nov. (Trouessartiidae) and Proterothrix cyornissimilis Constantinescu et al. sp. nov. (Proctophyllodidae: Pterodectinae). Both sexes of T. kharkhanensis differ from the closest species, T. rubecula Jablonska, 1968 by having setae si and c2 lanceolate and setae c3 and sRIII with acute apex. In males of the new species, the adanal apodemes have a hook-like retroverse apophysis and the internal margins of terminal lamellae have a shallow invagination at the level of setae h3. Both sexes of P. cyornissimilis differ from the closest species, P. cyornis Mironov and Tolstenkov, 2013, mainly by the ornamentation of the dorsal shields: it is absent on the prodorsal shield and poorly expressed on the hysteronothal shield. In males of the new species, the supranal concavity is triangular and the genital arch has a pair of small ovoid sclerites at its tips. http:/zoobank.org/urn:lsid:zoobank.org:pub:1671D6D4-8895-467B-A124-05EDBB0DF406

Anhemialges suteui n. sp. (Astigmata: Analgidae) from Hylia prasina (Cassin) (Passeriformes, Macrosphenidae) in Ivory Coast.

Anhemialges suteui n. sp. (Astigmata: Analgidae: Analginae) is described from the green hylia Hylia prasina (Cassin) (Passeriformes, Macrosphenidae) in Ivory Coast. The new species differs from the closest species, Anhemialges mironovi Kolarova, 2010, by the following features: in both sexes, solenidion σ on genu II is modified and widened in a form of leaf; dorsal setae c2, d2 and e2 are longer; and sternum and epimerites II are thinner. In males of the new species ambulacral discs of legs IV extend beyond the level of the lobar apices; in females, dorsal setae c2, d2 and e2 are situated on small oval shields and the anterior margin of epigynum exceeds the level of mesal extremities of epimerites II.

Two new species of feather mites (Acarina: Psoroptidia) from the Great Barbet, Psilopogon virens (Piciformes: Megalaimidae)

The paper describes two new species of feather mites collected on Psilopogon virens (Boddaert) (Piciformes: Megalaimidae) in India (Meghalaya): Megalaimobius massarae sp. nov. (Analgoidea: Pteronyssidae) and Picalgoides arbenzi sp. nov. (Psoroptoidea: Psoroptoididae). Males of M. massarae sp. nov. differ from the other three species of the genus by the shape of the transventral sclerite which is much deeper concave. The female of the new species has the external copulatory tub with an acute apex (this structure has a truncated apex in females of other species). Males of Picalgoides arbenzi sp. nov. differ from the closest species P. capitonis Černý, 1974 mainly by the shape of adanal apodemes which are fused into a large arch encircling the anal field. Females of the new species have the hysteronotal shield with acute posterior angles and setae d2 situated on the lateral margins of this shield (in females of P. capitonis the hysteronotal shield has the posterior angles rounded and setae d2 situated at a short distance from the lateral margins of this shield).

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

Abstract A new species of the feather mite genus Trouessartia (Trouessartiidae) is described from the Large NiltavaNiltavagrandis (Blyth) (Passeriformes, Muscicapidae) in Northeast India (Meghalaya, Jaintia Hills, Shnongrim village). Trouessartianiltavae Constantinescu, sp. n. is morphologically closely related (no phylogenetic meaning) to T.bulligera Gaud, 1968 from Clytorhynchushamlini (Mayr) (Passeriformes: Monarchidae), sharing in males a unique character within the genus, by having setae e on 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 between Trouessartia species are briefly discussed.

Descriptions of two new species of feather mites (Acarina: Psoroptidia: Pteronyssidae) from Ivory Coast

Two new feather mite species of the family Pteronyssidae Oudemans, 1941 collected from birds captured in Ivory Coast are described: Pteronyssoides cyanomitrae n. sp. from Cyanomitra obscura (Jardine) (Passeriformes: Nectariniidae) and Conomerus pygmaeus n. sp. from Hylia prasina (Cassin) (Passeriformes: Macrosphenidae). Pteronyssoides cyanomitrae n. sp. belongs to the nectariniae species group and differs from the closest species, P. garioui Gaud & Mouchet, 1959, in having, in males, the adanal shield present and setae f longer than setae d on the tarsus III; females of this species have the hysteronotal shield with two small median incisions on the anterior margin barely extending beyond the level of setae e2. Conomerus pygmaeus n. sp. is the first species of this genus found on a passerine host, and seems to be more similar to C. sclerosternus Gaud, 1990. This new species has the following distinctive characters: in females, the opisthosoma has small lobe-like extensions and the central sclerite is fused posteriorly with the lateral opisthosomal sclerites; in males, coxal fields I–IV lack large sclerotised areas.

A new feather mite species of the genus Proterothrix Gaud, 1968 (Acarina, Proctophyllodidae) from the Large Niltava, Niltava grandis (Passeriformes, Muscicapidae) – an integrative description

Abstract A new species of the feather mite genus Proterothrix (Proctophyllodidae: Pterodectinae) is described from the Large Niltava Niltava grandis (Blyth) (Passeriformes, Muscicapidae) in northeast India (Meghalaya, Jaintia Hills, Shnongrim village). Proterothrix chachulae Constantinescu, sp. n. differs from all known species of the genus by having in males the aedeagus with bilobate tip. The morphological description is supplemented with molecular characterisation of a fragment f near the 5` terminus of the mitochondrial COI gene.
