No subspecies are recognized. The status of the nominal taxon Trimicra angularis Alexander, 1917 described from the USA, and sometimes regarded as a subspecies of the present species is unclear; I provisionally regard it as a separate species Symplecta angularis. The status of the nominal taxon Mesocyphona testacea Lackschewitz, 1964 from central and north-eastern Asia is unclear as well; it has been considered as a subspecies of the present species, but is currently regarded as a separate species Erioptera testacea.
