Key to species of Thopha

The key to Thopha species provided by Moulds (2001) and updated in Moulds (2008) is here presented

in full with T. sessiliba clamoris incorporated (see also Fig. 5 ).

1 Head and thorax with bold, jet-black markings ........................................................................ 4

—— Head and thorax lacking bold, jet-black markings .................................................................... 2

2 Mesonotum with thoracic sigilla ill-defined ............................................ T. hutchinsoni Moulds

—— Mesonotum with thoracic sigilla boldly marked reddish brown ............................................... 3

3 Pronotum with midline always boldly marked reddish brown and colour of pronotal collar similar to remainder of pronotum ..................................................................................................... T. sessiliba clamoris subsp. n.

—— Pronotum rarely with midline boldly marked reddish brown, if so then colour of pronotal collar obviously paler than remainder of pronotum ........................................................................................ T. sessiliba sessiliba Distant

4 Postclypeus orange or muddy yellow in dorsal view ................................................................ 5

—— Postclypeus black in dorsal and ventral view ........................................... T. saccata (Fabricius)

5 Mesonotum with submedian sigilla marked party or entirely jet black .............................................................................................................. T. colorata Distant

—— Mesonotum with submedian sigilla not black but yellowish brown, similar in colour to mesonotum ........................................................ T. emmotti Moulds
