Psilogramma wannanensis Meng, 1990, Entomotaxonomia 12: 139. Type locality: China: Anhui, Xuancheng.
Note. Psilogramma wannanensis is distinguished from Psilogramma menephron by its smaller size, lack of a dorsal line on the thorax and in the truncate tip to the apical 'fishtail' process of the phallus. It is also characterized by a greyish-white ground colour to the forewing upperside and the white underside to the abdomen. These are essentially the features by which Psilogramma increta can be distinguished from Psilogramma discistriga. The only unusual feature is the shape of the phallus process; however, given the individual variation seen in the shape of this structure in Psilogramma increta, this could be interpreted as simply individual variation, albeit somewhat extreme. Thus Psilogramma wannanensis may just be an unusual form of Psilogramma increta. This requires further study.
