Key to species of Leofa (Prasutagus) Distant (males)

1. Aedeagal shaft with single spine-like ventral process ( Fig. 4I ) ................................. L. (P.) yangae sp. nov.

- Aedeagal shaft with one or two pairs of lateral processes............................................................................2

2. Aedeagal shaft compressed ( Figs. 3E, F ); pygofer processes bifurcate, wrench-shaped ( Fig. 3 B ). ............. ............................................................................................................................... L. (P.) forcipatus sp. nov.

- Pygofer and aedeagus not as above..............................................................................................................3

3. Apex of aedeagal shaft expanded in lateral view ( Fig.1F )...........................................................................4

- Apex of aedeagal shaft tapered in lateral view ( Fig. 1I ). ....................................................... L. (P.) curtulus

4. Basal triangular flanges of aedeagus wider and larger than the apical. ............................ L. (P.) palearctica

- Basal triangular flanges of aedeagus are nearly the same size as the apical ( Fig.1G ).. ...... L. (P.) pulchellus
