Invreiella cephalargia species-group

(Map 5)

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

1. Antennal scrobe carina position: inner tip well-separated from antennal rim.

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

3. Antennal rim: rounded to weakly tuberculate.

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

5. Genal process: triangular, posterior genal carina nearly straight.

6. Pronotal carina: weakly present, with cluster of dense, contiguous punctures in its place, edges of punctures tuberculate and crenulate, simulating carina.

7. Lateral face of pronotum sculpture: striate-rugose, with moderate punctures amid the striae.

8. Vertical column of punctures of mesopleuron: puncture edges tuberculate, forming crenulate anterior and posterior carinae.

9. Mesopleuron, metapleuron, and lateral face of propodeum sculpture, where present: conspicuously striaterugose, with moderate punctures amid striae.
