Descriptions of three new species of Ypsolopha Latreille (Lepidoptera: Ypsolophidae) from East Asia, redescription of Y. contractella (Caradja) and a checklist of East Asian Ypsolopha

Three new species of Ypsolopha Latreille are described from East Asia: Y. helva Sohn et Wu, n. sp., Y. sordida Sohn et Wu, n. sp., both from China; Y. pseudoparallela Sohn et Ponomarenko, n. sp. from Japan. Redescription of Y. contractella (Caradja), a poorly known species, is given with the first illustrations of genitalia of both species. The new combination, Ypsolopha diana (Caradja), transferred from Cerostoma, is proposed. Exclusion of Cerostoma xenicopis Meyrick from Ypsolopha is suggested with notes of its lectotype. The following new synonyms are proposed: Ypsolopha hebeiensis Yang, 1977 syn. n. = Y. leuconotella (Snellen, 1884); Ypsolopha affinitella (Staudinger, 1892) syn. n. = Y. dentella (Fabricius, 1775). Eight species are newly reported from China: Ypsolopha acuminata (Butler), Y. cristata Moriuti, Y. dentella (Fabricius), Y. japonica Moriuti, Y. nemorella (Linnaeus), Y. parenthesella (Linnaeus), Y. satellitella (Staudinger) and Y. yasudai Moriutu; two species are new to China and Korea, Y. amoenella (Christoph) and Y. asperella (Linnaeus); Y. contractella (Caradja) is new to Japan, Korea and China. A checklist of 42 species of Ypsolopha recorded from East Asia is provided.

New taxonomic data on the genus Ypsolopha Latreille (Lepidoptera, Ypsolophidae) with descriptions of two new species from the Russian Far East

Abstract Two new species of the genus Ypsolopha Latreille, 1796 are described from Far East of Russia: Ypsolopha melanofuscella sp. n. and Ypsolopha straminella sp. n. Two new synomymies are proposed: Ypsolopha ulingensis Yang, 1977, a new junior synonym of Ypsolopha costibasella (Caradja, 1939); and Cerostoma falculella Erschoff, 1877, a new junior synonym of Ypsolopha asperella Linnaeus, 1761. The species Ypsolopha costibasella Caradja, 1939, Ypsolopha nigrofasciata Yang, 1977 and Ypsolopha nigrimaculata Byun et Park, 2001 are recorded from Far East of Russia for the first time. The male genitalia of Ypsolopha nigrofasciata are described and illustrated for the first time, diagnostic genital characters are given.

A review of the genus Montescardia Amsel (Lepidoptera: Tineidae) from Japan, with reference to the genital morphology

The genus Montescardia Amsel is redescribed. Montescardia tessulatellus (Zeller) and M. kurenzovi (Zagulajev) are recorded and redescribed from Japan, with figures of the male and female genitalia. Functional morphology of the male genitalia in M. tessulatellus, the type species of Montescardia, is studied for the first time. The terminology used in the description is clarified taking into account the features of the skeleto‐muscular apparatus of the male genitalia and homologation of genital structures.

A new species of Anthonympha Moriuti (Lepidoptera: Plutellidae) from Russian Far East, with annotated check list of the genus.

Anthonympha rossica sp. nov., is described and illustrated. A checklist and key to the species of the genus are given. All the species are diagnosed.
