Description. Adult ( Fig. 11 ): Wingspan 10.0–10.7 mm. Head cream, frons light, off-white. Labial palpus strongly upcurved, far protruded over head; segment 2 cream with randomly spread brown scales, inner surface cream; segment 3 light brown except black at base and apex, acute. Thorax and tegula light brown. Forewing ochreous-brown mottled black; black scales concentrated mainly along costal margin and in subapical area; two small black dots at base and two others at corner of cell; straight cream subapical fascia at three-quarters; diffused black patch at base; diffused black fascia obliquely from one-quarter of costal margin to middle width of wing; cilia light grey, brown-tipped. Hindwing light grey.

Male genitalia ( Figs. 29, 30 ): Uncus long, rectangular, about twice long as broad. Gnathos small, weakly curved. Tegumen basally broad, distally narrow. Valva gradually curved, slightly exceeding top of uncus. Sacculus about one-third length of valva, narrow, outer margin weakly curved, inner margin straight or weakly curved; apex small, pointed, curved inwards. Paired processes on posterior margin of vinculum narrow, curved outward apically, slightly shorter than sacculus; medial excision deep and narrow. Paired processes of vinculum slightly shorter and broader in some paratypes. Saccus very short, narrow, pointed apically. Aedeagus distinctly flattened basally; distal portion straight, with weakly curved apical cornutus.

Female genitalia ( Figs. 48, 49 ): Papilla analis sub-oval, sparsely covered with short setae. Segment VIII sub-rectangular, distinctly longer than broad. Vaginal plates broad, with paired delicate foamy sculptured patches at base of Apophysis anterioris. Apophysis anterioris straight, shorter than segment VIII. Postvaginal plates relatively broad, rounded apically, extending to or slightly exceeding proximal margin of sternite VIII. Ductus bursae of moderate width; colliculum present. Corpus bursae sub-oval or rounded; signum thin, curved near base, straight distally.

Diagnosis. Scrobipalpa flavidinigra sp. n. resembles externally S. filia Povolný, 1969 , but its forewing is brighter, contrasted with more pronounced black patterns. The male genitalia resemble those of S. turcica Povolný, 2002 and S. strictella sp. n., but differ from the first species in the longer valva, shorter saccus, narrower sacculus and the differently shaped vinculum processes; it differs from S. strictella sp. n. in the narrower uncus, narrower sacculus, broader paired processes of vinculum and distinctly shorter saccus. The female genitalia resemble those of S. filia Povolný and S. nana Povolný, 1973 .

Biology. Host-plant unknown. Adults were collected in July and August at 1400 m altitude. Distribution. China (Inner Mongolia, Ningxia).

Etymology. The specific name is derived from the Latin flavidus – yellowish, niger – black, referring to the wing pattern.
