Diagnosis. A greyish brown species with three ochreous-brown spots in cell and contrasting ochreous-brown veins. Scrobipalpa buryatica sp. nov. and S. spumata have a similar wing pattern but usually predominantly light brown rather than greyish brown, and spots in cell are absent. Some specimens of the rather variable S. salinella and S. salicorniae are also very similar to S. ochronerva sp. nov., but differ in the more distinct and larger spots in the cell. Distinctly narrowed apically uncus, comparatively broad tegumen in combination with the broad sacculus and short and broad vincular process separate S. ochronerva sp. nov. from species of the S. salinella-instabilella complex. In this complex, S. salicorniae has the most similar male genitalia, but the uncus is twice as long as broad (1.5 times longer in S. ochronerva sp. nov.), the hump on the inner margin of the sacculus is absent and the posteromedial emargination of vinculum is narrower.

Description. Adult ( Fig. 67 View Figures 61–70 ).Wingspan 15.4 mm. Scales on head, thorax and tegulae grey, brown in distal part and tipped with grey, frons grey, labial palpus upcurved, uniformly greysh brown except off-white basal patch on inner surface of palpomere 2, scape greyish brown, antennal palpomeres greyish brown with indistinct whitish rings. Forewing greyish brown, three ochreous-brown spots in cell, veins distinctly mottled with ochreous-brown, cilia grey brown-tipped. Hindwing grey with dark veins, cilia light grey.

Male genitalia ( Fig. 128 View Figures 126–129 ). Uncus tongue-shaped, gradually narrowed posteriorly, 1.5 times longer than broad at base; gnathos hook moderately long, weakly curved; culcitula distinct, elongate; tegumen slightly longer than broad, anteromedial emargination extending to 1/3 of its length, transition to uncus indistinct; cucullus slender, gradually curved, of even width except slightly broadened at apex, extending to 3/4 length of uncus; sacculus 1/5– 1/4 length and 1.5–2 times width of cucullus, nearly parallel-sided, inner margin with short hump before pointed inwardly curved tip; vinculum twice as broad than long, posteromedial emargination broad, V-shaped, vincular process subtriangular, with outwardly curved pointed tip, distinctly shorter and as broad at base as sacculus; saccus broad at base, evenly tapered apically, slightly extending beyond top of pedunculus; phallus stout, caecum weakly inflated, strongly sclerotised along ventral margin, apical cornutus straight, distinct.

Female. Unknown.

Biology. The adult was collected in late June in a salt marsh biotope at an altitude of 600 m.

Molecular data. BIN: BOLD:AEC7268. The intraspecific average distance is unknown (n=1). The minimum distance to the nearest neighbour, S. salicorniae (BIN: BOLD:AAF1193), is 3.21% (p-dist); the minimum distance of BOLD:AAF1193 to the nearest neighbour, an unidentified Scrobipalpa from Spain and Italy belonging to the halophilous S. salinella group (BIN: BOLD:AAF1193), is 3.53% (p-dist) ( Fig. 10 View FIGURE 10 ).

Distribution. Russia: Buryatia.

Etymology. The specific name reflects the ochreous veins that are distinctive for the new species
