Since its original description with illustration (Figs. 1, 2) the species was not mentioned in Hampson’s catalogue (1903–1913), nor illustrated in Seitz (1912 –1938). The holotype of thoracica was illustrated by Krusek & Behounek (1996).The species has been placed in Donda by Poole (1989) and by Holloway (2009) and in Belciana by Krusek & Behounek (1996).
