All species of the genus are illustrated including the male of S. imperiatus Zolotuhin, 2001 which is described for the first time. 

A taxonomic review of Oberthueria Kirby, 1892 (Lepidoptera, Bombycidae: Oberthuerinae) with description of three new species.

The genus Oberthueria Kirby, 1892 is revised and three new species are described: O. yandu Zolotuhin & Xing Wang, sp. nov. (TL: China, Sichuan, Volong Reserve, Siguliang Shan), O. jiatongae Zolotuhin & Xing Wang, sp. nov. (TL: China, prov. Shaanxi, Taibaishan Mts (S), Tsinling Mts., Foping NT), and O. lunwan Zolotuhin & Xing Wang, sp. nov. (TL: Yunnan prov. (NW), Dali Bai autonom pref, Yulong county).

Another new species of the genus Phyllodesma (Phyllodesma) Hbner, [1820] 1816 from northern China (Lepidoptera: Lasiocampidae).

Phyllodesma permana sp. nov. is described from wastelands of northern China (Ningxia Hui AR). A new species is compared with Phyllodesma sinina (Grum-Grshimailo, 1891), Phyllodesma jurii I. Kostjuk, 1992 and Phyllodesma mongolicum I. Kostjuk Zolotuhin, 1994. Adults and male genitalia of two latter species are illustrated, and the differences among these taxa and Ph. permana sp. nov. are discussed. The holotype will be deposited in the Insect collection, College of Life Sciences, Nankai University (Tianjin, China). A list of the nowadays known from China Phyllodesma is given.

A new species of Typhonoya Prozorov (Lepidoptera, Lasiocampidae, Lasiocampinae, Gastropachini) from the moist broadleaf forest of the Democratic Republic of the Congo.

The second species of the genus Typhonoya Prozorov 2011T. kravchenkoi Prozorov, Mller Zolotuhin sp. n. from the Democratic Republic of the Congo is described. A previously monotypic genus becomes bitypic. One paratype specimen was collected in the buffer zone of the southern part of the Salonga National Park during a one year-long stationary expedition (June 2017June 2018). Spread imagoes, heads, legs, venations and genitalia of both species are figured and compared. Additional notes on the genus description and previously known species are added.

Ypsolopha admirandella sp. n. (Lepidoptera: Ypsolophidae), a new European species from the steppes of Russia.

The holotype of the new species is deposited in the collection of the Samara State University. The new species is associated with Ephedra distachya. The holotype and its genitalia, in addition those of the closely related Y. colleaguella Baraniak, 2007 are illustrated.

Types of Thyatirinae (Lepidoptera: Drepanidae) in the collection of the Zoological Institute of the Russian Academy of Sciences.

The article deals with 14 taxa of the Thyatirinae moths, the types of most of which are kept in the collection of the Zoological Institute of the Russian Academy of Sciences (St. Petersburg). It is shown that the designation of lectotypes/holotypes of Thyatira hedemanni Christoph, 1885, Asphalia nigrofascicula Graeser, 1888, and Cymatophora or var. terrosa Graeser, 1888, by Laszlo al. (2007) on the basis of specimens preserved in the collections of Berlin and London Museums was based on non-syntypic specimens, and that their designation as lectotypes needs to be corrected. Correct lectotypes are designated here for the taxa listed above as well for Gonophora dieckmanni Graeser, 1888, and Thyatira moellendorfi Fixsen, 1887; a lectotype of Cymatophora octogesima var. caucasica Krulikowsky, 1901, is designated from the collection of Kiev University.                The following type localities are thereby fixed: Lagodekhi [Georgia] for Thyatira hedemanni Christoph, 1885, Pung Tung [Central Korea] for Thyatira moellendorfi Fixsen, 1887 and for Thyatira violacea Fixsen, 1887, Nikolaevsk-na-Amure [Far East of Russia] for Cymatophora or var. terrosa Graeser, 1888.

Nomenclature and synonymic remarks on two species of Eupterotidae (Lepidoptera) described by Johan Christian Fabricius, and notes on related species.

Types of two species of monkey moths (Eupterotidae, Lepidoptera) described by Johan Christian Fabricius were located and are here figured for the first time, and lectotypes are designated for both species. The lectotype of Bombyx hibisci Fabricius 1775 is a male from the Hunterian Museum (Glasgow). The lectotype of Bombyx orientalis Fabricius 1793, originally listed from "Dom. Lund" was found in the Zoological Museum-University of Copenhagen (as temporarily loan from the Zoological Museum of Kiel University) with an old incorrect identification label. Both species are members of the genus Eupterote Hübner, 1820 (so-called Brachytera-lineage).                The following new synonymy can thus be established: Eupterote orientalis (Fabricius, 1793), comb. nov. (= Dreata geminata Walker 1855, syn. nov., syn. corr.; = Eupterote geminata var. hebes Grünberg 1914, syn. nov.; = Dreata anada Moore 1860, syn. nov., = Brachytera phalaenaria C. R. Felder, 1874, syn. nov., = Eupterote auriflua Moore, 1884, syn. nov.).          The type locality for orientalis originally given as "India orientali" is likely to be Sri Lanka.          The related taxon, Eupterote gardneri Bryk, 1950, stat. nov. is established as valid species (bona species) with the a new synonym, Eupterote bifasciata Kishida, 1994, syn. nov.          Eupterote primularis Moore, 1884 is considered a distinct species native to Central and Southern India.

A new species of the genus Phyllodesma (Phyllodesma) Hübner, [1820] 1816 from southern China (Lepidoptera: Lasiocampidae).

A new species, Phyllodesma kopetzi sp. nov. (type locality: China, W. Sichuan, Road Daocheng/Litang, 4100 m, N29°36.788', E100°19.825'), is described from the southwestern part of China's Sichuan Province. The holotype is deposited in the World Insect Gallery (Joniskis, Lithuania) collection. It is compared with the poorly known Phyllodesma sinina (Grum-Grshimailo, 1891) described from Sinin-Shan [Qinghai, China].

Five new species of the genus Ernolatia Walker, 1862 (Lepidoptera: Bombycidae) from islands of Malesia.

Five new species of the genus Ernolatia Walker, 1862 are described from the islands of Malesia. They are E. adrasteia sp. nov. (type locality: Philippinen, Negros occ., Mt. Kanlaon, 600-800 m, W-Route via Mambucal), E. invicema sp. nov. (type locality: S. Sulawesi, Puncak, Palopo, 2°55'S, 120°05'E), E. callirhoe sp. nov. (type locality: S. Sulawesi, Mt. Sampuraga, 2°10'S, 120°45'E), E. fumidiflora sp. nov. (type locality: Indonesia, N. Tengg. Timur, Flores, 9 km S Ruteng Golo Luseng) and E. doris sp. nov. (type locality: Indonesia, Sumba (W), Prov. Nusa Tenggara Barat, Gunung (Mt) Areas). The holotypes of all taxa are deposited in the coll. of entomological Museum Witt (which will be attributed to the Zoologische Staatssammlung, Munich). Their habitus, as well as available genitalia, are illustrated.

Review of the Alompra ferruginea Moore, 1872 complex with description of a new species from Taiwan (Lepidoptera, Lasiocampidae).

The present study reviews the Alompra ferruginea Moore, 1872 group. A. ferruginea bidiensis Tams, 1953 (TL: Borneo) and A. ferruginea cerastes Tams, 1953 (TL: Mindanao) are both raised to bona species level. The population of Taiwan is described as a new species, A. yibinfani sp. nov. The lectotype of A. ferruginea is designated from BMNH, the holotype of A. ferruginea cerastes is designated from USNM. A. ferruginea is listed here from Vietnam for the first time.

Revision of Lithosia Fabricius, 1798 and Conilepia Hampson, 1900 (Lepidoptera, Arctiidae).

This paper deals with the revision of the Arctiidae genera Lithosia Fabricius, 1798 and Conilepia Hampson, 1900. Only two species currently are considered to be members of Lithosia, Lithosia quadra Linnaeus, 1758, and Lithosia yuennanensis Daniel, 1952. It is here proposed to consider the Far-Eastern populations of L. quadra as subspecies Lithosia quadra dives Butler, 1877, stat. rev. and the Transcaspian populations of the species are described here as Lithosia quadra ssp. soligena ssp. nov. The lectotype of Phalaena Noctua deplana Linnaeus, 1771, preserved in the Hunterian Museum of London, is designated. Two species, Lithosia subcosteola Druce, 1899 and Lithosia gynaegrapha de Joannis, 1930, are excluded from Lithosia. The rare and local Lithosia quadra sikkima Strand, 1922 is raised to species rank and transferred to Conilepia, comb. et stat. nov. The male of C. sikkima is described for the first time. Three species are considered to belong to the genus Conilepia, among them Conilepia cao sp. nov., which is described from Vietnam. All taxa are described and figured. A scenario for the faunogenesis of the Lithosia-Conilepia complex is proposed using molecular data.
