Molecular data of S. sibirica. BIN: BOLD:AAW5788. The intraspecific average distance of the barcode region is 0.72% (n=6). The minimum distance to the nearest neighbour, S. ochrogera (BIN: BOLD:ACA7833), is 2.72%.
Molecular data of S. occulta. BIN: BOLD:ADR5477. The intraspecific average distance of the barcode region is unknown (n=1). The minimum distance to the nearest neighbour, unidentified Scrobipalpa from Pakistan (BIN: BOLD:AEA2484), is 3.18% (p-dist).
Molecular data. The maximum distance within four avalaible specimens of S. sibirica (NMPC-LEP-0399, TLMF Lep 22282, TLMF Lep 21804, BIDZ-00172) is 0.77 % (the mean distance 0.42 %). The mean distance between S. sibirica and S. occulta from S Ural (TLMF Lep 25657) is 3.74 % (p-dist) (Fig. 8).
Diagnosis. The species is characterized by the greyish black forewing with ochreous irroration in fold, under costal 1/2 and along veins in apical 1/ 3 in combination with pair of black spots edged with ochreous in the middle of the wing and in cell corner. Scrobipalpa smithi Povolný & Bradley, 1965 and S. occulta (Fig. 59) are very similar but usually paler with a more extensive ochreous pattern. The extremely broadened vincular process (twice as broad as sacculus) is the most characteristic diagnostic feature in the male genitalia. Similar species S. occulta has a narrower vincular process (1.5 times as broad as sacculus) (Fig. 160). The broad lobes of the ventromedial depression (broader than subgenital plates) are characteristic of the female genitalia of S. sibirica. Scrobipalpa occulta is similar, but has the lobes of the ventromedial depression as broad as the subgenital plates (Fig. 160). The vincular process of S. ochrogera (Fig. 119) is broader than in S. occulta but narrower than in S. sibirica.
Distribution. Russia: Altai, Tuva (new record), South of Krasnoyarskiy krai (Bidzilya 2009: 9); Kyrgyzstan (new record).
Remarks. Scrobipalpa occulta was described based on a single female (Fig. 59) collected near Istanbul, Turkey. Later, additional specimens including males were discovered in the southern Ural Mountains of Russia (Huemer & Karsholt 2010: 80–81). Scrobipalpa sibirica was described from a series of specimens collected in the vicinity of Beltir village, Altai Republic of Russia (holotype), other localities in the Kosh-Agatch district of Altai and one male from Krasnoyarskiy krai of Russia. All the studied females of S. sibirica differ both from the holotype of S. occulta and additional specimens of that species in the broader lobes of the ventromedial depression. We also found constant differences in the male genitalia (see above under Diagnosis) between S. occulta and S. sibirica. The morphological differences between these taxa are supported by molecular study: the mean distance between the S. sibirica and S. occulta from S Ural (Barcode TLMF Lep 25657) is 3.74 %. Hence, we reject the synonymy proposed by Huemer & Karsholt (2010: 80–81) and consider S. sibirica to be a separate species.
Scrobipalpa ochrogera was described based on five males collected in the Dzhambul region of Kazakhstan (Bishkek 70 km NNE) and one male collected 30 km E Naryn (Kyrgyzstan) (Fig. 60). The species is undoubtedly related to both S. sibirica and S. occulta but 3 % barcodes divergent justifies a separate species. We expect further taxonomic changes in this complex after variations in the female genitalia and males of S. occulta from the type locality have been studied. The molecular study seems very promising in this respect too.
