Diagnosis. Forewing length is 12.5–13 mm in males (12.5 mm in the holotype) and 14–14.5 mm in females. Barsine euryphaessa sp. n. is a closest relative of B. karenkensis . Externally, the new species differs from B. karenkensis by its slightly smaller size, broader, more diffuse pattern elements, longer antemedial spots, medial line being situated closer to the antemedial line, and shorter strokes in the submarginal area of hindwing. The male genitalia of B. euryphaessa sp. n. differ from those of B. karenkensis by their basally broader medial costal process, shorter distal costal process, narrower and more rounded membranous lobe of valva, distal saccular process being hooklike curved dorsally (that is straight in B. karenkensis ), globular and membranous subbasal ventral diverticulum (in B. euryphaessa sp. n., that is longer and narrower than in the new species and has a small cluster of small cornuti basally and granulation apically), much larger medial ventral diverticulum, and much broader lateral band-like cluster of cornuti. The female genitalia of B. euryphaessa sp. n. differ from those of B. karenkensis by their slightly narrower antrum being more weakly sclerotized and having a small anterior protrusion (in B. karenkensis , that is more broadly rounded anteriorly, more heavily sclerotized and has no anterior protrusion), and slightly narrower appendix bursae.

Distribution. North Vietnam.

Etymology. In Greek mythology, Euryphaessa is a Titaness, a mother of Helios (the Sun), Selene (the Moon) and Eos (the Dawn).
