Key to species of Etheophanus

1. Semi-lamellate process present on procoxa ( Figs. 2A & 5G )............................................ E. kuscheli

- Semi-lamellate process absent ( Fig. 2B ).................................................................... 2

2. Dorsal surfaces apunctate, alveolate microsculputure present and distinct, primary setae adpressed ( Figs. 1B & 1C )....... 3

- Dorsal surfaces rugose or puncate, microsculpture less distinct or absent, primary setae decumbent ( Figs. 1 D & 1E )...... 4

3. Aedeagus with median lobe in dorsal view narrowing to subrounded and slightly blunted, apex in lateral view strongly curved ventrally ( Fig. 5B )............................................................................ E. nitidellus

- Aedeagus with median lobe in dorsal view not narrowing to apex and rounded apically, apex not strongly curved ventrally ( Fig. 5C )................................................................................... E. optandus

4. Pronotal vibrissae present ( Figs. 3A & 2B ), dorsal surfaces weakly punctate and rugose, median lobe with serrate edges. North Island, generally distributed north of Taupo.......................................................... E. pinguis

- Pronotal vibrissae usually absent ( Fig. 2E ), dorsal surfaces strongly punctate, median lobe with simple edges. North and South Islands, generally distributed south of Taupo, and in the South Island...................................... E. striatus
