7. Camponotus horni Kirby  HNS  . Palm Creek, burrow nest under stone.

Kirby says: " The peculiar structure of this species will probably ultimately necessitate its removal to another genus, but the: rufous body and purple abdomen will render it easily recognisable." In this statement he is correct, for the worker is Iridomyrmex detectus Smith  HNS  , the most common and widely distributed ant in Australia. The female appears to be a valid species, and is, here redescribed as Camponotus (Tanaemyrmex) horni Kirby  .
