Diagnosis.

Distinguished from X. strix strix by somewhat narrower dark field on forewings and from X. strix retinax by actual presence of this dark field (Figs 5–10) and fold of ductus bursae (Figs 69–71); from both subspecies by bigger pollex in male genitalia (Figs 42, 43, 45) and genetically, having an average p - distance of 1.89 % from X. strix strix and 1.75 % from X. strix retinax . Average p - distance between X. strix stangelmaieri and X. graminea is 2.28 %, X. strix stangelmaieri and X. chagnoni, 6.77 %, X. strix stangelmaieri and X. indirecta, 8.06 % (Fig. 90). Very local, so far found only on the Adriatic coast near Venice in northern Italy (Figs 91, 92).
