A taxonomic revision of the genus Chaquihua is presented confronting new material with the literature descriptions of the genus. The nymph and male imago are described here for the first time and the existing descriptions of other developmental stages are complemented. Association of larvae and winged stages is now confirmed by rearing. The synonymy of the extant species is proposed. Notes on the biology and distribution of the genus are also included.
