Key to species of Glenoleon

1 Forewing costal area uniareolate basally ( Fig. 85c )........................................................... 2 - Forewing costal area biareolate basally ( Fig. 79c ).................................................... G. froggatti

2 (1) Hind wing without transverse bands in distal half of wing ( Fig. 85c )............................................. 3

- Hind wing with two transverse dark bands in distal half of wing ( Fig. 88c ).............................. G. pulchellus

3 (2) Tibial spurs long (reaching T1 apex); forewing radial crossveins simple ( Fig. 85c ); forewing membrane mostly hyaline (if with brown marks, marks not rounded)........................................................................ 4

- Tibial spurs short (about half T1 length); forewing radial crossveins irregularly cross linked ( Fig. 81b ), forewing membrane with numerous large, dark, rounded spots........................................................ G. maculatus
