It can be recognised by the following characters: head (Figs 1a-4a , 5 ) with erect piliform scales, transfrontal suture inverted V-shaped; antennae 0.7 x length of forewing, scape without pecten, flagellomeres with single annulus or two annuli of contrasting-coloured scales; labial palpus spatulate, bearing lateral bristles; forewing often brightly coloured, with venation (Fig. 6 ) complete, CuP weak; hind-wing with M3 or CuA1 absent; female with single frenulum bristle; segment VIII reduced and highly modified, usually asymmetrical in male; male genitalia (Figs 7 - 10 ) strongly asymmetrical, incorporating part of sternum VII and sternum VIII; aedeagus fused with right valva; gnathos absent; uncus lobes usually fused; female (Fig. 11 ) oviscapt reduced, posterior apophyses short, anterior apophyses rudimentary or absent, sternum VIII hardly developed. Distribution. Worldwide; the distribution of each species is given in Table 2 . Table 2. World checklist of the genus Dryadaula Meyrick, 1893.
