Description of Sphaleroptera orientana meridionalis subs. n. (Lepidoptera: Tortricidae: Cnephasiini) from the Pale di San Martino Mountain plateau (Dolomites, NE Italy).

On the base of newly collected material, a new subspecies of the alpine endemic moth Sphaleroptera orientana Whitebread, 2006 (Lepidoptera: Tortricidae) from the Pale di San Martino Group (Dolomites, Northern Italy) is described. Morphological characters of the adults and DNA barcode suggests the presence of allopatric populations of S. orientana in the South-eastern Alps, attributable to two distinct subspecies: S. o. suborientana Whitebread, 2006 in the Catinaccio, the Sella, and the Fanes group, and Julian Alps, and S. o. meridionalis subs. nov. known from the Pale of San Martino group. The main biogeographic barrier is constituted by the complex of the Fiemme valleys-Val di Fassa-by the Pordoi Pass and by the Val Cordevole which from west to north to east separate the distribution area of S. o. suorientana from S.o. meridionalis.

Sattleria enrosadira sp. nov., a new cryptic, high alpine species from Northern Italy revealed by DNA barcodes and morphology (Lepidoptera, Gelechiidae).

Sattleria karsholti Huemer Hebert, 2011 is re-examined based on recently collected material, museum vouchers, and DNA barcodes. Adult and male genitalia morphology and molecular data of the COI barcode region support the existence of two allopatric species, S. karsholti, from the type locality of Pizo Arera in the Orobian Alps (Bergamo Province, Italy), and S. enrosadira sp. nov. from Monte Baldo, Adamello and the Brenta group (Trento and Verona Provinces, Italy). Adults and male genitalia of both species are figured; the females of both species are unknown.

Megacraspedus laseni sp. nov. (Lepidoptera: Gelechiidae) from the Dolomites of north-eastern Italy.

Megacraspedus laseni sp. nov. is described from Dolomiti Bellunesi (Veneto Region, Prov. Belluno, Italy). The habitus of the adult and male genitalia are described and illustrated whereas the female sex remains unknown. The new species belongs to the Megacraspedus pentheres species group and is closely related to the southern alpine M. eburnellus Huemer Karsholt, 2001 from which it differs in morphological characters and in DNA barcode sequence. Megacraspedus carolustertius Gastón Vives, 2020 is synonymized with M. quadristictus Lhomme, 1946, syn. nov.

Description of the female of Sattleria sophiae Timossi, 2014 (Lepidoptera: Gelechiidae).

The female of Sattleria sophiae Timossi, 2014 is identified on the basis of DNA barcoding, described, illustrated and its habitat is discussed.

Sattleria revisited: unexpected cryptic diversity on the Balkan Peninsula and in the south-eastern Alps (Lepidoptera: Gelechiidae).

The taxonomy of Sattleria Povolný from the high mountain systems on the Balkan Peninsula and the adjacent parts of the Alps (south-eastern Alps, Dinaric Alps, Rila Mountains) is revised based on recently collected material and re-examined museum vouchers. Adult morphology and molecular data of the COI barcode region support the existence of six strictly allopatric species in this area, including four new species: Sattleria sophiae Timossi, sp. nov. (Parco Paneveggio-Pale di San Martino, Dolomites, Prov. Trento, Italy), Sattleria dolomitica Huemer, sp. nov. (Eastern Dolomites, Prov. South Tyrol, Italy), Sattleria dinarica Huemer, sp. nov. (Durmitor NP, Dinaric Alps, Montenegro) and Sattleria haemusi Huemer, sp. nov. (Rila Mts., Bulgaria; Sar Planina, Macedonia).
