Key to species of Neaenus

1. Venation evident; tegmina mottled ( Figs 10 E–H); length> 8 mm............................ Neaniscus subg. nov....4

- Venation obscure; tegmina with patches of color, or evenly colored ( Figs 10 A–D); length < 7 mm..... nominate subgenus...2

2. Tegmina usually with pale spots beyond base; aedeagus with paired apical processes...................... varius Fowler

- Tegmina unmarked or with pale base; aedeagus without paired processes......................................... 3

3. Male subgenital plates tapered; style serpentine ( Fig. 46 A)........................................... natrix sp.nov.

- Male subgenital plates with prominent lobe near base; style straight, apically furcate ( Fig. 47 A)........ hystricosus sp.nov.

4. Tegmina striped in brown and yellow ( Fig. 10 E–F); female with base of ovipositor exposed ( Fig. 11 A)........ gilli sp.nov.
