The Hermonassa pallidula species group

The Hermonassa pallidula species group is close to the Hermonassa dictyota group. Externally it differs from most other Hermonassa spp. by relatively large size (wingspan 38-40 mm), rather broad forewing shape and pale yellowish brown colour of forewing with weak main elements of the Noctuinae pattern and contrast black or dark brown orbicular and reniform stigmata. The male genitalia of the species of Hermonassa pallidula group are similar to those of the Hermonassa dictyota species group. The Hermonassa pallidula species group comprises following taxa: H. pallidula , H. hoenei , H. ellenae (with the subspecies H. e. ellenae , H. e. tapaishana , and H. e. robusta ), and H. albimacula sp. nov.
