Diagnosis.
The species can be recognised externally by the greyish black forewing with a distinct light brown pattern along the veins and small black markings.
Scrobopapla inferna
is very similar, but has more distinct black markings;
S. mongolica
Povolný, 1969
differs in a less distinct light brown suffusion in the dorsal half of the forewing.An elongate apically rounded uncus in combination with a short broad sacculus with pointed and posteriorly directed tip, narrow vincular process and deep posteromedial emargination of the vinculum are characteristic of the male genitalia. In
S. mongolica
the saccus is broader, and the sacculus is narrowed at the base and extends to 1/3 length of cucullus (not narrowed at base and extends to 1/5 length of cucullus in the new species). The female genitalia are characterised by the slender, deeply divided lobes of the ventromedial depression, subgenital plates distinctly covered with foamy sculpture, broad ductus bursae with indistinct transition to short corpus bursae and sigmoid signum with small basal plate.
Scrobipalpa grisea
Povolný, 1969
,
S. frugifera
and some other species have a somewhat similar sternum VIII but the broad ductus bursae, small narrow corpus bursae and sigmoid signum are characteristic of
S. altubura
sp. nov.
Description. Adult
(
Figs 42, 43
). Wingspan 14.0–
14.7 mm
. Head, thorax and tegulae covered with grey, brown-tipped scales, frons paler, light grey to off-white, labial palpus upcurved, palpomere 2 grey densely mottled with brown, inner and upper surface white, palpomere 3 white with broad brown basal and medial rings, scape brown mixed with pale especially distally, flagellomeres brown ringed with light grey. Forewing greyish brown, distinctly mottled with black along margins and in subapical 1/4, diffuse oblique black pattern at base and in medial 1/3 between subapical vein and fold, two black spots in fold, pair of black spots in middle and in cell corner, black longitudinal streak at 3/
4 in
middle of wing, subapical vein and fold light brown, brown pattern along dorsal margin, in distal portion of cell and along veins in subapical area, diffuse light grey transverse fascia at 3/4; cilia greyish brown, black tipped. Hindwing and cilia light grey.
Variation. The specimens look darker, greyish brown or paler, light brown depending on the extent of the brown or grey scales.
Male genitalia
(
Figs 101, 102
). Uncus twice as long as broad, posterior margin rounded; gnathos hook very short, weakly curved, culcitula well developed; tegumen distinctly elongate, anteromedial emargination extending to 1/3 length; cucullus about of even width, weakly broadened at base and in apical portion, apex weakly pointed, slightly extending beyond top of uncus; sacculus as broad or slightly broader than cucullus at base, about 1/5 length of cucullus, parallel-sided to 2/3 length, then narrowed towards pointed and posteriorly directed tip; vinculum twice as broad as long, posteromedial emargination broad, in shape of lyre, vincular process narrow, slightly shorter than sacculus, with outwardly curved pointed tip; saccus gradually narrowed apically, extending beyond top of pedunculus; distal portion of phallus moderately broad, weakly narrowed towards rounded or pointed apex, apical arm narrow, down-curved, caecum 1/3–1/2 length of phallic tube, weakly inflated.
Female genitalia
(
Fig. 146
). Papillae anales slender, elongate, sparsely covered with short setae; apophyses posteriores 5 times as long as apophyses anteriores; segment VIII as long as broad at base, gradually narrowed posteriorly, sternum VIII with triangular posteromedial emargination, subgenital plates subrectangular, about 1/3 width of sternum VIII, densely covered with fine microtrichia, with digitate subovate patch of foamy sculpture extending from base of apophyses anteriores to half length of sternum VIII along its anterior margin, lobes of ventromedial depression slender, digitate, weakly covered with foamy sculpture anteriorly, divided by deep triangular incision anteriorly, extending anteriorly to 3/4 length of sternum VIII; apophyses anteriores slightly shorter than segment VIII, straight; colliculum narrow, ring-shaped; ductus bursae gradually broadened to 1/3 length, then of equal width, with indistinct transition to corpus bursae, corpus bursae ovate, slightly broader than ductus bursae, basal plate of signum very small, distal hook sigmoid, narrowing distally, directed posteriorly, placed at right side near entrance of ductus bursae.
Biology.
Adults have been collected in steppe biotopes from late May to late July up to
1250 m
in mountains.
Molecular data.
BIN: BOLD:ADR6355. The intraspecific average distance of the barcode region is 0.11 (n=8). The minimum distance to the nearest neighbour,
S. reiprichi
(BIN: BOLD:ACY6331), is 4.85 % (p-dist) (Fig. 5).

Etymology.
The specific name is combined from words “al” “tu” “bur”—the first words of the administrative regions (
Altai
,
Tuva
,
Buryatia
) where the new species occurs.
