Type species Rasa litanga Saldaitis et Yakovlev , sp.n.

DESCRIPTION. Female. Size medium. Antenna bipectinate, length of crest processes (in middle third of antenna) 1,2 times bigger than rod diameter. Length of antenna equal to 0.5 of fore wing length. Tegula and patagium pale brown. Abdomen covered with orange hairs. Fore wing pale brown, with poorly expressed dark brown pattern of transverse strokes and blurred patches and spots. Hind wing pale brown without pattern.

Female genitalia: ovipositor long, papilla analis semicircular, smooth; posterior apophyses thing, 2 times longer than anterior apophyses; posterior apophyses basally thick, apically narrowing; ostium poorly immersed, cup-like, of small diameter; antrum short, thick; ductus short; bursa bag-like, of medium size, without signa, ductus seminalis flows into place of antrum transition into ductus.

Male unknown.

DIAGNOSIS AND TAXONOMIC POSITION. Judging by the external characters and female genital structure, the new genus belongs to the subfamily Cossinae Leach, 1815 (type genus Cossus Fabricius, 1793 ). This is indicated by the long ovipositor, the small cup-like ostium, the specific appearance of the adult. It is necessary to note that females only of fifteen Cossinae genera (among the 69 described valid genera of the world fauna) have bipectinate antenna: Paropta

The most important distinctive features of the new genus are: the specific fore wing pattern and strong basal thickening of the anterior apophyses. Currently, it is impossible to indicate exactly the allied genera.
