title: Allopsoroptoides galli n. g., n. sp., a new genus and species of feather mites (Acari: Analgoidea: Psoroptoididae) causing mange in commercially raised domestic chicken in Brazil.
abstract: A new feather mite, Allopsoroptoides galli n. g., n. sp. (Psoroptoididae: Pandalurinae), is described from the domestic chicken, Gallus gallus (Linnaeus) (Galliformes: Phasianidae), from Brazil. This is the first record of a representative of the feather mite family Psoroptoididae from an avian host of the order Galliformes. The new genus is closely related to the genus Cygnocoptes Fain & Bochkov, 2003 but clearly differs from the latter and all other genera of the family by the loss of four median pairs of hysteronotal setae (c1, d1, e1, and h1) in both sexes and by the unique shape of the male opisthosoma. Instead of the bilobate opisthosoma, the male opisthosoma in this genus has a narrow and long median projection, ending with a pair of semi-ovate terminal lamellae. These mites were first detected during a mange outbreak in several commercial poultry facilities in the state of São Paulo, Brazil.
