Invreiella australis species-group

(Map 3)

Members of this female-based species-group are recognized by the following combination of character states:

1. Antennal scrobe carina position: inner tip close to antennal rim.

2. Frons and antennal rim position: frons not transversely recessed and concave below antennal scrobe carina, antennal rim consequently not recessed and is visible when head viewed laterally.

3. Antennal rim: tuberculate and protruding.

4. Clypeus: concave, with transverse arcuate carina complete, with small lateral tubercle ventrad to carina.

5. Genal process: denticulate to triangular, posterior genal carina sinuate to straight.

6. Pronotal carina: present, glabrous, crenulate due to overlapping lateral punctures, visible both dorsally and laterally.

7. Lateral face of pronotum sculpture: little to mostly punctate throughout with moderate punctures.

8. Vertical column of punctures of mesopleuron: puncture edges weakly tuberculate, not forming anterior or posterior carinae.

9. Mesopleuron, metapleuron, and lateral face of propodeum sculpture, where present: microgranulate with moderate punctures and micropunctures.
