Type material. Holotype ♂, Russia, Tuva rep., 50°44’N 93°08’E, E. Tannu-Ola mts., Irbitel r.[iver], stony steppe slopes, 13–16.vi.1995 (Jalava & Kullberg) (gen. slide 203/16, OB) (MZH). Paratype: 1 ♂, Russia, Altai Republic, 45 km N of Ulagan vill., Chulyshman valley, 51°01′56″N; 88°00′43″E, grassy steppe, rocks, 600 m, 26–27.vi.2019 (Šumpich) (gen. slide 265/20, OB) (Barcode NMPC-LEP-0608) (NMPC).
Diagnosis. The species is characterised externally by the white head and yellowish brown forewing with a blackish brown pattern and black markings in the cell. Similar species S. pulchra is brighter, and the ochreous brown pattern is more distinct. The elongate uncus, long vincular processes (exceed length of sacculus), and phallus with a cluster of short spines are characteristic of the male genitalia. Scrobipalpa maniaca shares the two first characters, but the uncus is about 1/2 length of tegumen (1/ 3 in S. albiflava sp. nov.), the vincular process with tips more strongly curved outwardly, and the phallus with the caecum more strongly inflated and without the cluster of spines.
Description. Adult (Figs 57, 58). Wingspan 12.0–14.0 mm. Head white, labial palpus white with diffuse light brown basal and medial rings, inner surface of palpomere 2 white, scape white mixed with light brown, flegellomeres white ringed with brown. Thorax and tegulae white slightly shaded with light brown. Forewing yellowish white, mixed with brown along costal margin, in cell and in subapical 1/3, veins mottled with light brown, pair of black spots edged with light brown at 1/3 and 2/ 3 in middle of wing, diffuse black marks at base and in fold, indistinct white transverse fascia at 3/4; cilia white, brown-tipped. Hindwing light grey, cilia lighter, yellowish white.
Male genitalia (Figs 117, 118). Uncus twice as long as broad, nearly parallel-sided, weakly constricted in middle, posterior margin with shallow medial emargination; gnathos short, slender, weakly curved; tegumen gradually narrowed posteriorly, outer margins emarginated at 2/3 length, anteromedial emargination broadly rounded, extending to 1/3 length of tegumen; cucullus gradually curved, weakly narrowed before half, apex rounded, extending to posterior margin of uncus; sacculus about 1/4 length and as broad as cucullus at base, inner margin straight, outer margin weakly constricted in middle and rounded in distal half, with distinct pointed weakly inwardly curved tip; vincular process broader than sacculus at base, slightly narrowed and outwardly turned in distal portion, inner margin strongly edged, far extending beyond top of sacculus, vinculum slightly broader than long, posteromedial emargination deep, V-shaped; saccus slender, slightly narrowed towards rounded apex, slightly extending beyond top of pedunculus; phallus about of equal width, apex rounded with short thorn, apical lobe narrow, down-curved, cluster of spines on right side beyond half, caecum weakly swollen, 1/4–1/3 length of phallic tube.
Female genitalia. Unknown.
Biology. Adults have been collected from mid to late June in rocky steppe biotopes.
Molecular data. BIN: BOLD:AEK6016. The intraspecific average distance of the barcode region is unknown (n=1). The minimum distance to the nearest neighbour, an unidentified species of Scrobipalpa from Kazakhstan (BIN: BOLD:AEC9258), is 4%.
Distribution. Russia: Altai, Tuva.
Etymology. The specific name is derived from the Latin album, meaning white, and the Latin flavum, meaning yellow, referring to the forewing colouration characteristic of this species.
