New genus and seven new species of Brazilian eriophyoid mites and redescription of Catachela machaerii Keifer (Acari: Prostigmata: Eriophyoidea)

Abstract

Surveys on several naturally occurring plants in southeast Brazil led to the discovery of a new genus and seven new species of eriophyid mites. Athrix n.g. is described based on the type species Athrix lissoscutum n.sp. collected on Heteropteris aceroides Griseb; Athrix brevitibia n.sp. is described from Heteropteris anoptera Juss.; Aculus bistichos n.sp. is described from Guapira opposita (Vell.) Reitz.; Cenaca exigua n.sp. is described from Chrysophyllum gonocarpum (Mart. & Eichl.) Engl.; Cosella macrothrix n.sp. is described from Ficus pumila L.; Diptilostatus lofegoi n.sp. is described from Myrcia guianensis (Aubl.) DC; Diptilostatus mesae n.sp. is described from Clidemia hirta (L.) DC and Catachela machaerii Keifer is redescribed.
