Diagnosis. The adults of the new subspecies are separable from the Taiwanese ssp. pali Hreblay & Ronkay, 1998 by their regularly darker forewings, brown coloured and faint violet–shaded submarginal area, without or with only weak ochreous suffusion, conspicuously shorter reniform stigmata and by the darker, more extensive brown suffusion of the marginal area of the hindwings; the other elements of the wing pattern show no remarkable differences. The new subspecies (Figs 14–16) is somewhat larger in size than the insular ssp. pali (wingspan 30–35 mm, length of forewing 16–18 mm, versus 28–32 mm and 14–16 mm, respectively) (Fig. 13). Nevertheless, the proper separation is strongly supported by the geographical distribution, since the nominotypical subspecies is endemic in Taiwan while the new subspecies occurs in continental China.

The male genitalia of the two subspecies, ssp. pali and ssp. continentalis, are almost identical. Euplexia pali continentalis ssp. n. (Figs 25, 26) can be separated from the Taiwanese nominotypical subspecies (Fig. 24) by its larger cucullus, somewhat ventrally crooked lateral process of the harpe, finely hooked aedeagus and the stronger longitudinal sclerotization of vesica.

The female genitalia of the new subspecies (Fig. 34) are also similar to those of the nominotypical subspecies (Fig. 33), but the sclerotized plate of the antrum is trapezoidal, the distal section of ductus bursae is more sclerotized-wrinkled than in the insular ssp. pali, having two (a small and a larger, rather mushroom–shaped) strongly sclerotized plates, and the appendix bursae is somewhat smaller. In the ssp. pali, the antrum is almost evenly broad, the sclerotised plates of the distal section of ductus bursae are remarkably smaller, and the appendix bursae is larger than in the ssp. continentalis .

Biology and distribution. The new subspecies of E. pali is known from continental China, from the provinces Shaanxi, Hubei and Sichuan. It occurs in medium–high altitude woodlands; the specimens of the type–series were collected between 1150–1820 m elevations.

Etymology. The name refers to the occurrence of the new taxon in the continental China.
