Notes. (1) This taxon was synonymised with Th. signata by Hampson (1900) and was subsequently considered as its synonym ( Strand 1922; Fang 2000; Volynkin & Dubatolov 2017) or subspecies ( Daniel 1954). (2) The species was described from two females ( Leech 1899), which are syntypes. In order to stabilise the nomenclature, the syntype labelled as “Type” is hereby designated as the lectotype.

Diagnosis. The forewing length is 17.5–18.0 mm in males and 18.5–19.0 mm in females. Thysanoplisna directa is morphologically similar to Th. tenebrosa sp. nov. and the detailed comparison is provided below in the diagnosis of the latter.

Distribution. Central China (Shaanxi and Hubei Provinces) ( Leech 1899; Daniel 1954 (partim., as ‘ Lithosia signata ssp. brevimaculata [sic.])).
