2. Head with ocellar region reticulate ( Fig. 20 )............................................................... 3

-. Head with ocellar region lacking distinct reticulation......................................................... 4

3. Fore wing largely pale with three weak transverse darker markings.......................................... glynn

-. Fore wing extensively dark but with basal fifth sharply pale............................................. williamsi

4. Fore wing clavus uniformly brown ( Fig. 8 )................................................................. 5

-. Fore wing clavus mainly pale, with either base or apex brown.................................................. 6

5. Antennal segment III almost as pale as IV and V; pronotal reticles delimited by pale, flange-like ridges (cf. Fig. 18 )..................................................................................................... diaspora

-. Antennal segment III dark brown, in contrast to yellow IV and V; pronotal reticles delimited by bold sculpture lines ( Fig. 5 )........................................................................................... julatteni sp.n.
