Invreiella cardinalis species-group

(Map 4)

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

1. Antennal scrobe carina position: inner tip separated from 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: weakly tuberculate to tuberculate.

4. Clypeus: concave, with transverse arcuate carina broadly interrupted medially, area merely punctate, resulting in bilateral carinate processes each with enlarged tubercle ventrad to process.

5. Genal process: triangular to spinose, posterior genal carina convex to sinuate.

6. Pronotal carina: present, glabrous, weakly crenulate, visible both dorsally and laterally.

7. Lateral face of pronotum sculpture: with moderate punctures, somewhat striate-rugose.

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

9. Mesopleuron, metapleuron, and lateral face of propodeum sculpture, where present: microgranulate with micropuntures and moderate punctures, rugose-granulate to rugose-striate in some areas.

Species included: I. acuminata Waldren, sp. nov., I. cardinalis (Gerstaecker, 1874), and I. cuernavaca Waldren, sp. nov.
