Key to species of Sigmoleia in New Zealand (males)

1 M1 sinuous ................................................................................................................................................................... 2

- M1 straight ................................................................................................................................................................... 3

2 M1 strongly sinuous, its basal portion running almost parallel to M2 ( Fig. 14 ) .......................... melanoxantha Edw.

- M1 moderately sinuous, its basal portion diverging from M2 ( Fig. 15 ) .................................................. similis sp. n.

3 Ventrolateral processes much longer than basal portion of gonocoxites, process apices curved mesally and thus approaching each other ( Fig. 65 ) .......................................................................................................... separata sp. n.

- Ventrolateral processes as long as basal portion of gonocoxites, along their entire lengths curved mesally and thus strongly approaching each other ( Fig. 69 ) ......................................................................................... peterjohnsi sp. n.
