title: A new genus and species of pterygosomatid mite (Acari: Pterygosomatidae) parasitizing Callopistes maculatus (Squamata: Teiidae) from Chile.
abstract: A new genus and species Callopistiella atacamensis gen. nov. and sp. nov. (Acariformes: Pterygosomatidae) are described from Callopistes maculatus (Squamata: Teiidae) in Chile. In this species, both sexes are characterized by the hypostome without a velum, the chelicerae proximally globose and very thin distally, ending in a movable digit curved outward, the fixed cheliceral digit reduced to a membranous and sparsely serrate structure, presence of seta 2c, tarsus I with seta ft nude and 2 times longer than solenidion ω2; larvae have solenidion ω1 on tarsus I and tibia I without solenidion φ and moderate hypertrichy present around the genital area. Some biological aspects of this new species are discussed.
