Synegiodes histrionaria Swinhoe, 1892 , Trans. ent. Soc. Lond. 1892 (1): 12. Syntypes Ƌ, India: Khasi Hills (BMNH).

Diagnosis. A reliable external distinguishing character of S. histrionaria compared to S. sanguinaria , except those mentioned already under sanguinaria , is the straight medial line of hindwing, composed of short costal and anal streaks, with the large discal spot in the middle. S. sanguinaria has a round anal spot, a distinctly smaller discal spot with less white in the centre, and no costal spot or streak. Further comparisons on external characters and genitalia see under S. sanguinaria . S. ornata (Bastelberger) , has for long been treated as a subspecies of S. histrionaria , but is raised to species-rank again. For differences of these similar and closely related species see below, under S. ornata .
