Genus Hydredes Volynkin & Matov , gen. n.

Type species: Hydredes yakobsoni Matov & Volynkin , sp. n.

Diagnosis. The new genus differs from Protarchanara by Photedes -like habitus of adults (small moths, with short and wide forewings), absence of abdominal androconial brushes in males and conspicuous structures of the male and female genitalia. In the male genitalia, Hydredes can be distinguished from Protarchanara by the small and poorly separated cucullus, less sclerotised costa, ventral costal edge with a slight depression medially, costal process forming a right angle with costa, smaller penicular lobes; in the female genitalia, the appendix bursae possess a sclerotised plate.

Description. Adult. Relatively small moths. Forewing short, wide, triangular. The wing colouration varies from brown or ochreous brown to pale yellow. Male genitalia. Uncus moderately long, thin, apically pointed; tegumen short, penicular lobes relatively small, rounded. Vinculum short, U-shaped. Valva elongate; clavus smooth; costa poorly sclerotised; costal process long, thin, apically pointed, form an acute angle with costa. Cucullus small, rounded, poorly separated. Corona present. Aedeagus moderately long, slightly curved; vesica with one or two large claw-like cornuti. Female genitalia. Ovipositor weakly sclerotised, pointed. Apophyses anteriores and posteriores thin, long. Antrum broad, with thin sclerotised margin. Ductus bursae short, membranous, its anterior part is sclerotised. Corpus bursae very long, narrow, membranous; its posterior part is sclerotised. Appendix bursae broad, bulbous, strongly sclerotised, ventrally with strongly sclerotised semilunar plate.

Etymology. The genus name is a combination of the generic names Hydraecia Guenée, 1841 and Photedes Lederer, 1857 .
