42. Xyrosaris lucae sp. nov. Description of adult (Plate 6). Wingspan: 10–13 mm. Head tufted, whitish, face shining; labial palpus segment 3 of similar length to segment 2, but covered with whitish scales; antenna about ¾ length of wing, scape pale brown, flagellum annulate pale brown and whitish. Thorax and tegula whitish. Forewing ground colour whitish suffused pale brown, paler in dorsal half of wing, three black dots near costa in basal half of wing, a further row of 4–5 dots along fold, a black spot beneath fold at about 1/8, a black line around apex, fringe dark fuscous at apex. Hindwing narrow, pale grey. Abdomen and legs whitish brown. Male genitalia (Plate 16). Uncus square, socius long and curved, valva crescent-shaped, saccus over half length of valva. Aedeagus about twice length of valva, containing a single long cornutus. Female genitalia (Plate 26). Lamella postvaginalis lobes separated by a gently concave space, ostium small, conical, ductus almost as long as abdomen, at first with scobination on one side, a sclerotised scobinate zone immediately before corpus bursae which widens gradually, signum comprised of a stellate plate with spines protruding laterally. Diagnosis. Distinguished from other species by having the dorsal half of the forewing rather paler than the costal half, in the male genitalia by the very distinctive shape of the valva and in the female especially by the signum with its long spines.
