Key to species of Nsesa (males)

1 Pygofer dorsal appendage branched ( Fig. 21e ); aedeagus with shaft evenly curved dorsad, processes small or absent ( Fig. 21i ) ................................................................................................... 2

- Pygofer dorsal appendage unbranched (may have small apical teeth); aedeagus with shaft straight or slightly sinuate through most of length, with long processes....................................................................... 3

2 Aedeagus without processes ( Figs 21i, j ); branches of pygofer appendage nearly equal in length ( Fig. 21e ).................................................................................... N. cameroonica Cao & Zhang sp. nov.

- Aedeagus with small spinelike preapical processes; dorsal branch of pygofer appendage much shorter than ventral branch.................................................................................. N. mpanza Dworakowska

3 Aedeagus with two long distal processes arising at or very near apex, subequal in length and extended distad............ 4

- Aedeagus with three distal processes...................................................................... 5

4 Pygofer dorsal appendage evenly tapered to acute point, extended to apex of lobe.............. N. matteba Dworakowska

- Pygofer dorsal appendage with apex bearing small toothlike projections, not reaching apex of lobe..................................................................................................... N. napmza Dworakowska

5 Aedeagus with distal processes extended basad, one long and single, other two shorter and arising from common stem; pygofer appendage short with blunt apex....................................................... N. rajskii Dworakowska
