New synonyms and redescription of two little-known Thiodia species (Lepidoptera, Tortricidae): T. ursulana (Kennel, 1919) comb. nov. and T. klapperichi (Razowski, 1967) comb. nov.

The lectotype of Semasia ursulana Kennel, 1919 is designated. The name of the species is recombined as Thiodia ursulana (Kennel, 1919) comb. nov. and considered as a senior synonym of Thiodia aequilibris Tsvetkov, 2017 syn. nov. The female genitalia of this species are described for the first time. Eucosma buratana Blackstein, 2014 syn. nov. described from Tajikistan is synonymised with Thiodia klapperichi (Razowski, 1967) comb. nov. The latter species was known from the male holotype from Afghanistan. We report T. klapperichi from Turkmenistan for the first time and describe hitherto unknown female of this species. Adults and male genitalia of the type specimens of T. ursulana and T. klapperichi are illustrated. Thiodia glandulosana Walsingham, 1907 is transferred to Epinotia Hbner [1825]: Epinotia glandulosana (Walsingham, 1907) comb. nov. An annotated checklist of 27 species of Thiodia is given. In addition, the holotypes of Thiodia dahurica (Falkovitsh, 1965), Thiodia densistriata (Falkovitsh, 1964) and Thiodia hyrcana Kuznetzov, 1976 are illustrated for the first time.

New records of pyraloid moths (Lepidoptera: Pyraloidea) from different regions of Ukraine.

New records of Cochylini moths (Lepidoptera: Tortricidae) from the Balkans.

In the course of expeditions conducted on the Balkan Peninsula by Ignc Richter in 20042019, altogether 45 species of Cochylini moths were collected. The examination of the collected specimens revealed one new species of the genus Aethes: Aethes larissae sp. nov., from the North Macedonia. Additionally, a new subspecies, Aethes kindermanniana macedonica ssp. nov. is described from the North Macedonia too. Phtheochroa amasiana (Ragonot, 1894) and Cochylimorpha erlebachi Huemer Trematerra, 1997 are recorded from the Balkans for the first time. A male of Aethes eichleri Razowski, 1983 is collected for the first time, and DNA barcoding data of this species was obtained. We established a new synonymy: Aethes eichleri Razowski, 1983 syn. nov. of Aethes francillana (Fabricius, 1794). Illustrations of specimens and photographs of the genitalia of all described taxa are provided.

New records of little known pyraloid moths (Lepidoptera: Pyraloidea) from Ukraine.

A list of seventeen rare and little known species of Crambidae and Pyralidae from Ukraine is given. Hyperlais claralis (Caradja, 1916) stat. rev., comb. nov. is recorded for the first time for Europe. Five species are found in Ukraine for the first time: H. claralis, Titanio ledereri (Staudinger, 1870), Lambaesia pistrinariella (Ragonot, 1887), Gymnancyla gilvella (Ragonot, 1887) and Sciota lucipetella (Jalava, 1978). Two neglected European species-Lambaesia pistrinariella and Ancylosis monella (Roesler, 1973), are confirmed to occur in Europe. The lectotype of L. pistrinariella is designated and the species is recorded for the first time from Russia. The hitherto unknown females of H. claralis and L. pistrinariella are described. The differences between H. claralis and other related Hyperlais-species are briefly discussed. The adults and the genitalia of H. claralis, H. dulcinalis (Treitschke, 1835), Udea institalis (Hübner, 1819), A. monella, L. pistrinariella, Bradyrrhoa confiniella (Zeller, 1848), B. imperialella (Ragonot, 1887) and G. gilvella are illustrated. The biology of Loxostege clathralis (Hübner, 1813), Epischidia fulvostrigella (Eversmann, 1844), B. imperialella and Pempeliella bulgarica Slamka Plant, 2016 is described based on observation by the third author in Crimea. Salicornia perenanns Willd. is recorded as a new host plant for G. gilvella and Halocnemum strobilaceum (Pall.) M. Bieb.-as a new host plant for E. fulvostrigella. Epischidia caesariella (Hampson in Ragonot Hampson, 1901) and Pempeliella sororiella (Zeller, 1839) are removed from the list of Pyralidae of Ukraine due to misidentification.

Description of a new genus, a new species and a new subspecies of snout moths (Lepidoptera: Pyralidae: Phycitinae) from Eastern Europe and Central Asia.

Yelenka gen. nov. is established to accommodate two species initially described in the genus Nephopterix Hübner, [1825] 1816-Yelenka hastiferella (Ragonot, 1887) comb. nov. and Yelenka gengisella (Ragonot, 1893) comb. nov. Additionally, a new species Yelenka calciferella sp. nov. from Ukraine, Russia and Western Kazakhstan, and its mountain subspecies Yelenka calciferella uyghurica ssp. nov. from Eastern Kazakhstan and Mongolia are described. The new genus is placed into the subfamily Phycitinae. Yelenka gengisella (Ragonot, 1893) sp. rev. is taken out from synonymy with Myrlaea orcella (Ragonot, 1887). Yelenka gengisella and Y. hastiferella are redescribed based on type material and additional specimens. According to DNA barcode, Y. gengisella and Y. hastiferella are placed in the same BOLD BIN. However, these species exhibit pronounced morphological characters that clearly distinguish the two taxa on the species level. The lectotype is designated for Nephopteryx [sic] hastiferella Ragonot, 1887. Comparative diagnoses, a key to species, illustrations of external characters, also male and female genitalia are provided for all species.

Notes on taxonomy and distribution of some Palaearctic Ancylosis Zeller, 1839 (Lepidoptera: Pyralidae: Phycitinae).

A review of the genus Ancylosis Zeller, 1839 (Lepidoptera: Pyralidae: Phycitinae) from Ukraine.

Nine species of Ancylosis are recorded from Ukraine. Ancylosis larissae sp. nov. related to A. hellenica (Staudinger, 1870) and A. rhodochrella (Herrich-Schäffer, 1852), is described from Crimea. Ancylosis albicosta (Staudinger, 1870) is reported from Ukraine for the first time. Ancylosis albidella Ragonot, 1888, A. syrtella (Ragonot, 1887), A. rhodochrella, A. harmoniella (Ragonot, 1887) and A. monella Roesler, 1973 are removed from the list of Pyralidae of Ukraine due to misidentifications. The host plants for A. sareptalla (Herrich-Schäffer, 1861) and A. substratellum (Christoph, 1877) comb. nov. are recorded for the first time. New host plant is recorded for A. roscidella (Eversmann, 1844). The diagnoses for all species known from Ukraine are provided. The adults and genitalia of both sexes are illustrated for all Ukrainian species and some closely related species from adjacent territories. A key to the species is given based on external characters and the genitalia of both sexes. The female genitalia of A. deserticola (Staudinger, 1870), A. hellenica (Staudinger, 1870), A. sabulosella (Staudinger, 1879) as well as the male genitalia of A. pallida (Staudinger, 1870) are described and illustrated as they have been dealt incorrectly in literature. The status of A. albidella and the records of this species from Europe are discussed. The new synonymy is proposed: Ancylosoma Roesler, 1973 syn. nov. of Ancylosis Zeller, 1839 and A. sareptalla gulbaharensis Roesler, 1973 syn. nov. of A. sareptalla (Herrich-Schäffer, 1861).
