Description

The previously suggested association of Tonza with Plutellidae is reevaluated. One congener, Tonza citrorrhoa Meyrick, 1905, is newly recorded from Japan. Adult morphologies of T. citrorrhoa are described with photographs and illustrations, and the wing venation and genital structures of Tonza are described for the first time. New diagnostic characters are proposed for Tonza and they include: antennae almost same length of forewing; forewing with only three radial plus radial sector veins; in male genitalia, both uncal processes and socii present; in female genitalia, lamella antevaginalis strongly sclerotized. These generic characters seem to better associate Tonza with Attevidae rather than Plutellidae.
