Diagnosis. Gibberifera simplana is closely similar to G. glaciata by sharing the following character: cucullus oblong. However, based on the remarks of Kawabe & Nasu (1994) and Zhang (2021), it can be distinguished by the following characters: vertex white (dark brown in G. glaciata ); inner edge of median fascia of forewing moderately concave (straight in G. glaciata ); uncus Y-shaped (widely bifurcated in G. glaciata ); absence of non-deciduous cornuti in vesica (presence of one or two non-deciduous cornuti in G. glaciata ).
