Diagnosis. Externally, the species differs from its closest relative, S. inscripta , by the absence of crosslines on forewing and paler hindwing. The male genitalia of S. sanguinea differ from those of S. inscripta by the medially broader uncus, slightly larger medial costal process, longer apical membranous lobe of valva, longer and s-like curved distal saccular process, smaller aedeagus (in comparison with the genital capsule), and presence of three clusters of spines in the vesica (whereas in s. inscripta there are only two clusters). The female genitalia of S. sanguinea differ from those of S. inscripta by the longer apophyses anteriores, broader antevaginal plate, broader ductus bursae, broader appendix bursae, and stronger spines in the posterior section of corpus bursae.

D i s t r i b u t i o n. China (Shanghai, Zhejiang, Yunnan).
