Psilogramma hainanensis Eitschberger, 2001 [Invalid]

Synonymized with Psilogramma discistriga discistriga by Kitching and Rougerie et al., 2018, Biodivers. Data J. 6: e22236. Psilogramma hainanensis was distinguished from Psilogramma hauensteini [= Psilogramma discistriga discistriga] by the shapes of the vinculum and the apical "fishtail" process of the phallus, shorter "colliculum" [= antrum] and the larger corpus bursae. However, all these features are highly variable within species of Psilogramma, and are not indicative of species status. Furthermore, DNA barcode data place the allotype of Psilogramma hainanensis deep within a large cluster formed of numerous samples of Psilogramma discistriga discistriga (BIN AAA2713). Consequently, Psilogramma hainanensis is here considered to be a junior synonym of Psilogramma discistriga discistriga.
