Two new species of feather mites (Acarina: Psoroptidia) from the Huet's fulvetta, Alcippe hueti (Passeriformes: Leiothrichidae), in China

Two new feather mite species collected from the Huet's fulvetta, Alcippe hueti (Passeriformes, Leiothrichidae), in China are described: Proterothrix dinghushani sp. n. (Proctophyllodidae) and Trouessartia pauciseta sp. n. (Trouessartiidae). Males of P. dinghushani have a pair of lateral hysteronotal sclerites and a closed pentagonal sclerotized frame in the postero-median part of propodosoma. Females of this species have the sternum 1/4 of the total length of epimerites, and the terminal cleft exceeds half of the length of the lobar shield. Both sexes of T. pauciseta have a distinctive character, the absence of 3 pairs of hysteronotal setae (d1, d2, and e2), that clearly differs this species from all previously known species of the genus.

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 feather mites of the subfamily Pterodectinae (Analgoidea: Proctophyllodidae) from Indonesia

Two new pterodectine feather mite species collected in Indonesia (Kalimantan) are described: Montesauria indonesiana sp. n. from the Asian glossy starling Aplonis panayensis (Scopoli, 1786) (Passeriformes, Sturnidae), and Proterothrix murariui sp. n. from the White-rumped woodpecker Meiglyptes tristis (Horsfield, 1821) (Piciformes, Picidae). Males of M. indonesiana have adanal and opisthoventral circular shields, surrounding the base of setae g and ps3, respectively, and females have the anterior and lobar parts of hysteronotal shields well delimited from each other by a transverse groove. The new species of Proterothrix described here is the first species of this genus discovered on a host of the family Picidae. This species has unique character states and cannot be included in any of the species groups defined so far within the genus. In both sexes, dorsal hysterosomal setae c1 are absent and hysterosomal setae cp are spiculiform. Males of P. murariui have a pregenital sclerite (epiandrum), the aedeagus is band-shaped, thickened in the anterior half and narrowed in the posterior half, the terminal lobes have two pairs of trapezoidal membranous extensions, coxal fields I are almost closed, and coxal fields III are open. Females have a narrow terminal cleft, parallel-sided in the anterior 2/3, large and with oblique margins in the posterior 1/3.

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.

A new species of feather mite: Timalinyssus Mironov, 2001 (Astigmata: Pteronyssidae) from Garrulax canorus canorus (Linnaeus) (Passeriformes: Timaliidae) in China

Many regard the Pteronyssidae as a subfamily of Avenzoariidae Oudemans, 1905, but Mironov (2001) recently recognized the group as a family, based on the unique character of a ventral membrane on tarsi I, and other distinguishing features of the Pteronyssinae Oudemans, 1941 (vide: Gaud & Atyeo 1996) and the specificity their host associations. To date, 140 species in 23 genera are described (Mironov 2001, 2005). The genus Timalinyssus was established by Mironov (2001) to accommodate two species collected from babblers (Passeriformes: Timaliidae). It is closely related to Mouchetia Gaud but differs in the following characters: prodorsal shield is fused with the scapular shields, c2 setiform and short in both sexes; tarsi III are cone-like with acute apex in male; opisthosomal lobes are long and separated by narrow terminal cleft in female (Gaud & Atyeo 1996; Mironov 2001).
