Abstract
The genus Protarchanara Beck, 1999 is revised. The new genus Hydredes gen. n. (type species Hydredes yakobsoni sp. n.) is described. Three new species, Hydredes yakobsoni sp. n., H. shchetkini sp. n. and Protarchanara mythimnoida sp. n. are described from Central Asia. Two species, Arenostola delattini Wiltshire, 1953 and Hydraecia praecipua Hacker & Nekrasov, 2001 are transferred to the genus Hydredes gen. n. Protarchanara brevilinea impudica (Staudinger, 1892) stat. n. is upgraded to subspecific level. Lectotypes for Namangana contumax Püngeler, 1902, Sidemia (Luperina) johni Püngeler, 1914 and Nonagria impudica Staudinger, 1892 are designated. The adults and male and female genitalia are illustrated.
