Diagnosis. This genus is quite similar to Yponomeuta in appearance, but can be easily distinguished from it by the apically dilated gnathal arm and the inverted U-shaped sclerite (Fig. 8 b) on the eighth abdominal segment in male, and by the compactly fused Sc and R1 veins of the hindwing (Fig. 1). Moriuti (1977) described the generic characters in detail.
