Key to the larval Lucanidae described from Tasmania

1 Frontal suture V-shaped ( Fig. 5 A); reduced dorsal anal pad present ( Fig. 5 K)........................... Lissotes rudis

- Frontal suture U-shaped ( Fig. 2 A); dorsal anal pad absent ( Fig. 2 K)............................................. 2

2 Granular carinae on right plectrum greater than 45 ( Fig. 3 H); raster interrupted toward apex ( Fig. 3 M); lateral anal lobes encir- cled by well-spaced fringe of setae ( Fig. 3 L); right mola ovoid, concave and undivided ( Fig. 3 G)...... Hoplogonus simsoni

- Granular carinae on right plectrum fewer than 45; raster continuous; setae on lateral anal lobes variable; right mola undivided or with two separate cusps............................................................................. 3

3 Right mola ovoid, concave, and undivided ( Fig. 2 G); lateral anal lobes with ventral apex densely setose posterior to septula ( Fig. 2 M); granular carinae on right plectrum 36–39 ( Fig. 2 H).............................. Hoplogonus bornemisszai

- Right mola divided into two separate cusps ( Fig. 4 G); lateral anal lobes encircled by well-spaced fringe of setae ( Fig. 4 L); granular carinae on right plectrum 38–42 ( Fig. 4 H)...................................... Hoplogonus vanderschoori
