Polyrhachis tanami

Polyrhachis tanami is known only from a single locality in the Tanami Desert and nothing is known of its nesting habits.

Identification
Polyrhachis tanami is characterised by its small size and distinctly and rather deeply sculptured body. It is relatively similar to Polyrhachis tenebra, with which it shares rather strongly posteriorly converging margins of the promesonotal dorsum (PMI 176-177 in P. tanami versus 172 in P. tenebra) and virtually identically shaped petiolar spines. However, P. tenebra has the dorsum of the head and mesosoma more finely reticulate-punctate with the sculpture on the anterior pronotum, including the humeri, and most of mesonotum and propodeum partially hidden by relatively long, appressed, pale golden pubescence.
