Depressaria sibirella Lvovsky, 1981 ( Figs 190–192 )

Material examined. RUSSIA: ALTAI REPUBLIC: Aktash vill., 50°19′12″N, 87°36′00″E, grassy steppe, rocks, 1400 m, 21.vi.2015, 1 Ƌ (Barcode NMPC-LEP-0167), J. Šumpich leg. ( NMPC).

Molecular data. BIN BOLD: ADM1760 (n = 3, 3 public, 3 from Altai). No intraspecific divergence of the barcode region is presented.

Comments on Depressaria altaica and D. schaidurovi

Depressaria altaica Zeller, 1854 (Figs 193–198)

Type material examined. LECTOTYPE: ³ ( ZMHB), KAZAKHSTAN: labeled “Altai”, [A. Kindermann leg., ex. coll. J. Lederer].

Additional material examined. RUSSIA: ORENBURSKAYA OBLAST: Schibendy valley, 20 km S of Pokrovka, 1.v.2003, 1 Ƌ (gen. prep. DEEUR 4603 P. Buchner), (Barcode KN00082), K. Nupponen leg. ( RCKN); the same locality but 28.ix.2005, 1 Ƌ (gen. prep. DEEUR 6465 P. Buchner), (Barcode TLMF-Lep-26340 [failed]), K. Nupponen leg. ( RCKN).

Molecular data. Only one successfully barcoded specimen of D. altaica is stored in the BOLD (sample ID KN00082) (Figs 195–196) but we do not have access to its complete data or its BIN. However, the owner of this record, Kari Nupponen, has provided us with the sequence for comparison with related taxa, and as a result, 8.9% p-distance between D. altaica and D. schaidurovi can be presented.

Distribution. Kazakhstan (Altai) ( ZELLER 1854, LEDERER 1855), Tajikistan ( LVOVSKY 1981), Russia (South Ural). New species for Russia.

Remark. Philipp Christoph Zeller described D. altaica based on material collected by Albert Kindermann in Western Altai (SE Kazakhstan) during his expedition along the Irtysh River between Ust-Kamenogorsk and Ust-Bukhtarminsk ( LEDERER 1855, cf. also VOLYNKIN & YAKOVLEV 2015). Type series according to the original description contains two males and one female, and Zeller explicitly presents their deposition in the “Mus[eum]. Lederer” ( ZELLER 1854), which means that the type material stayed deposited in Julius Lederer’s collection at that time. At present, Lederer’s collection is part of Microlepidoptera collection in ZMHB, and two types of D. altaica were found there: one male designated as lectotype by J. Hannemann ( HANNEMANN 1953) (Fig. 193) and one female labeled by Hannemann as “allotypoid” ( Figs 199–201 ); the third type is most probably lost. Both types have a locality label only with the name “Altai”, handwritten by Lederer (Fig. 194) (the handwriting was compared with labels below Lederer’s types, cf. also VOLYNKIN & YAKOVLEV 2015). This locality was published by ZELLER (1854), and later incorrectly assigned to the Russian Altai ( LVOVSKY 1981).

The lectotype was dissected by Hannemann and the drawing of its genitalia was published under the number “ Lectotypus Nr. 42“ ( HANNEMANN 1953). The female was found undissected by the first author of this paper; subsequently it was dissected ( Figs 199–201 ) and also barcoded (sample ID MFN-29197-H10). Surprisingly the result did not correspond with genetical data of the male collected in southern Ural (Fig. 195, material cited above) while its genitalia (Figs 196) fully fit the lectotype. Genitalia of the female paralectotype (“Allotypoid 43”) correspond with Depressaria schaidurovi Lvovsky, 1981 according to the characters on female genitalia published by LVOVSKY (2004).

Therefore, the type series of D. altaica consists of two different species, both undescribed before 1854. Hannemann’s designation of the male as the lectotype defined the present concept of D. altaica Zeller, 1854 . It belongs to the D. discipunctella / D. veneficella species group according to the male genitalia and genetical data, female of this species remains unknown. The female paralectotype belongs to D. schaidurovi described by LVOVSKY (1981).
