Key to Australian Syllophopsis species

The following key to Australian Syllophopsis is based on Heterick (2001) with modifications by Brian Heterick and Steve Shattuck.

1

 * Promesonotum distinctly humped, mesopleuron shining with little or no sculpturing => Syllophopsis australica
 * Promesonotum flattened posteriad, mesopleuron and lateral surfaces of propodeum usually microreticulate => 2

2

 * Mesopleuron shining and unsculptured (series from Cannon Vale, Qld) => near Syllophopsis subcoeca
 * Mesopleuron matt and microreticulate => near Syllophopsis sechellensis
