Pronematinae (Trombidiformes: Iolinidae) from Brazil, with original and complementary descriptions of taxa as well as with a reappraisal of the subfamily and of Parapronematus

Pronematinae was originally proposed as a subfamily of Tydeidae Kramer, 1877 and later transferred to Iolinidae Pritchard, 1956. Although apparently omnivorous, some species of this group have been reported as predators of mites. New collection records of Pronematinae from Brazil are presented. The original descriptions of Peridasilcoferla paraensis De Vis and Ueckermann n. gen. n. sp. and Parapronematus connarus De Vis and Ueckermann n. sp. are presented. Complementary descriptions of Parapronematus geminus Meyer and Rodrigues, 1966 and Naudea richinda Meyer and Rodrigues, 1966 are also presented, based on the examination of type specimens. A reappraisal of the subfamily and of Parapronematus Baker, 1965, is made based on the specimens collected and on literature information. Updated keys to the world genera of Pronematinae and to the world species of Parapronematus as well as suggestions of new generic characteristics to be considered in descriptions of new Pronematinae taxa are presented.
