Lista angustusa  sp. n. Figs 1, 13, 23


The new species is very similar to Lista haraldusalis  in wing pattern, but the wing color of the new species is darker than the latter. In the male genitalia, it can be distinguished from the latter by the narrower valva, having two lateral spines in the gnathos, and lacking spines in the uncus.


Adult. Forewing length 8.5-11.0 mm (n = 7). Head pale yellow, mixed with brown; labial palpus upturned, third segment pointed; antenna brown, scape extension black, with pale grey scales on inner side, and blackish-brown on outer side. Thorax mixed with pale yellow, blackish-brown and pale grey scales. Forewing covered with brown, yellow and pink scales; base mixed with yellow and black scales; postmedial fascia orange with dark brown edges, outer area covered with fuscous and dark pink scales; cilia brown. Hindwing with same pattern as forewing.

Male genitalia (Fig. 13). Uncus broad, densely suffused with setae, apex truncated. Gnathos incurved apically, with three spines at apex and a long spine laterally located. Valva nearly the same width from base to apex, apex obliquely truncated; costa obviously sclerotized, apex swollen; sacculus expanded at base, with two processes in middle, the inner one larger, with serrated edge, the outer one small thorn-like, a sclerotized plate from sacculus to valva medially located. Juxta constricted and bifurcated, two pointed plates at apex. Phallus cylindrical, curved slightly.

Female genitalia (Fig. 23). Ovipositor nearly round, suffused with setae. Apophysis anterior and apophysis posterior nearly same length. Ductus bursae short, membranous. Corpus bursae elliptic, with two rounded signa.
