In male genitalia tegumen broad; peniculus well developed, flattened, ear-like; uncus long, slightly twisted, falciform; valva long, with parallel costal and ventral margins; costa narrow, base of costa strongly projected dorsally at right angle to the dorsal margin of valva, in some cases costa with large extension in distal third; sacculus large; harpe missing; cucullus sclerotised; juxta large and strongly narrowed posteriorly; aedeagus moderate, coecum large well expressed, cornuti absent.

In the present treatment the genus includes seven species with confirmed generic association. Three of them are widely distributed in Palaearctic, one is distributed in the Far Eastern countries, two are known only from
China
and one (
Deltote bellicula
) is Nearctic. A number of taxa placed in “
Lithacodia
” and “
Erastria
” (

) waiting for the revision.
