Diagnosis. Ancylosis xylinella is a large species distinguishable by the forewing having a broad pale yellow costal band (about 1/4 width of the forewing) with a downward angle at distal 1/3. Antemedial line is same to forewing ground color, indistinct, edged with dark brown on outer side, postmedial line is pale yellow, edged with dark brown on inner side, discal cell is pale yellow mixed with brown and dark brown. The male genitalia of A. xylinella can be distinguished by the uncus with rounded apex, the gnathos with inflated apex and the valva gradually narrowing after the sacculus. The female genitalia of A. xylinella can be distinguished by the short ductus bursae (about 1/6 length of corpus bursae) and the elongate large corpus bursae with cone-shaped spines arranged in several longitudinal rows along the length of corpus bursae.

Distribution. China ( Ningxia, Shaanxi, Xinjiang), Afghanistan, Algeria, Saudi Arabia, Egypt, Iran, Iraq, Lebanon, Mongolia, Morocco, Palestine, Russia (South of the European part, southern Siberia, Far East), Spain, Tunisia.
