Abstract
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.
Highlights
With over 100 known species, Indonesian archipelago is ranked 11th in the world with respect to recorded feather mite biodiversity (Doña et al 2016)
Studies on feather mites in this area began over 100 years ago, with the first papers realized by early acarologists on the feather mite fauna associated with parrots (Psittaciformes) (Trouessart 1884, 1885; Favette and Trouessart 1904)
Descriptions of feather mite species from other hosts orders in Indonesia are scattered in various taxonomic papers (Bonnet 1924; Atyeo and Braasch 1966; Santana 1976; Peterson and Atyeo 1977; Pérez and Atyeo 1981; Gaud et al 1985; Gaud and Atyeo 1986, 1987; Atyeo and Gaud 1992; Dabert and Ehrnsberger 1996; Mironov et al 2002, Dabert et al 2002; Mironov 2006; Dabert and Labrzycka 2009)
Summary
With over 100 known species, Indonesian archipelago is ranked 11th in the world with respect to recorded feather mite biodiversity (Doña et al 2016). The fauna of parrots in this country, varied and spectacular, with endemic or rare species, has continued to fascinate acarologists over time; so other feather mites species from these hosts have been described or reinvestigated in a series of papers published in the past forty years (Atyeo and Pérez 1982; Atyeo and Gaud 1991; Gaud and Atyeo, 1996; Mironov and Perez 2003; Mironov and Dabert 2010; Mironov et al 2003, 2014). A comprehensive paper, dedicated to feather mites that live on birds from the family Megapodidae (Galliformes), includes 34 species of feather mites from Indonesia (Atyeo 1992). Each is a potential host for several feather mite species, so it is evident that the
