Diagnosis. The new subspecies differs from the typical D. furiosa specimens by the lighter reddish-ochreous grey colouration, often with some violaceous shade of the forewings and by the more prominent but rather diffuse maculation and crosslines. Forewings apically elongate triangular; antemedial line dark reddish brown, broad, zigzagged; postmedial line more sharply defined, crenulate; intermaculation between orbicular reniform stigmata and subterminal shadow diffuse and only slightly darker than ground colour; hindwings nearly concolorous ochreous-grey with some reddish shade. The females are slightly robuster and larger in expanse than the males (36–39 mm vs. 38–42 mm).

paratypes, Tadjikistan: 60 = Turkestanskiy Mts , slide No.: VZ 11436m; 61 = Zeravshan Mts ,

slide No.: VZ 11487m

The male genitalia ( Figs 60–63 View Figs 59–61 View Figs 62–64 ) are rather similar to those of D. furiosa furiosa , however the small subbasal diverticulum with the small, needle shaped cornutus is slightly more prominent. Valvae broad with nearly straight ventral margin, clasper nearly straight, acute terminally.

The female genitalia ( Fig. 77 View Figs 77–79 ) agree with those of D. furiosa furiosa , the appendix bursae is about 1/3 shorter than corpus bursae and less saccate.

Distribution and bionomics. This subspecies is distributed eastwards of the range of the nominotypical D. furiosa and occurs on a relatively large area in the hilly regions of Kirghisia and Tadjikistan, mostly in low and medium altitudes. The moths show a relatively long flight period from mid-June to mid-July.

Etymology. The name refers to the characteristic colouration of the subspecies.
