Pronotum ( Fig. 1 View FIGURE 1 G) with posterior margin straight. Forewings ( Fig. 1 View FIGURE 1 G) mostly opaque; membrane extending only over first apical cell; most of corium with plexus of veins, this absent on apical and brachial cells; clavus with crossveins between claval veins and between inner claval and claval margin. Hindlegs with femoral setal formula 2:1:1; first tarsomeres with length approximately equal to combined length of posterior ones. Other external characters as in generic description ( Young 1977: 285).
