Diagnosis. Forewing length is 14–17 mm in males and 17–18 mm in females. The continental new subspecies (Figs. 21–24) differs externally from the island nominate subspecies (Figs. 17–20) by its slightly larger size, and significantly broader and orange red transverse lines of forewings (while in C. quadripartita quadripartita the forewing transverse lines are much narrower and pale red). The male genitalia of C. quadripartita vieta ssp. nov. (Figs. 35, 36) differ from those of C. quadripartita quadripartita (Fig. 34) in the slightly larger medial posterior diverticulum and the broader and longer medial anterior diverticulum. The female genitalia of the new subspecies (Fig. 44) differ from those of the nominate subspecies (Fig. 43) in the broader and longer antrum, the broader appendix bursae, and the presence of a small, second signum in the corpus bursae.
Distribution (Fig. 46). The subspecies is known from Vietnam (provinces Lao Cai, Vinh Phu, Thua Thien Hue, Kon Tum, Lam Dong).
Etymology. The subspecific epithet refers to the country of the taxon distribution: Vietnam (Vietnamese: Việt Nam).
