5. Upper mesopleuron densely punctate like lower one (Fig. 19C); male clypeal moustache not meeting medially (Fig. 20C).. 6

- Upper mesopleuron smooth and shiny, unlike punctate lower area (Fig. 6B); male clypeal moustache meeting medially (Fig. 5D)................................................................................................ 7

6. Mesoscutum shiny ferruginous (Fig. 6B) (rest of thorax yellow except black median sulcus), nearly smooth (impunctate), densely punctate at junction with scutellum; gastral T 2 sparsely punctate (Fig. 19E)......... Philanthus variegatus Spinola

- Mesoscutum shiny black, scutellum and postscutellum ferruginous, propodeum black with two lateral yellow patches (Fig. 21B); mesoscutum sparsely punctate, punctures dense posteriorly (Fig. 21B); gastral T 2 with more or less dense punctures (Fig. 21C)............................................................... Philanthus variegatus ecoronatus Dufour

- Gastral T 3 black, or with very reduced yellow markings (Fig. 5A, C), unlike those of T 2 and T 4; T 1 sometimes with ferruginous; T 3 finely shagreened, with very fine widely spaced punctures.......................... Philanthus coarctatus Spinola

8. Pronotal collar distinctly emarginate antero-medially (Fig. 9C); mesopleuron and propodeum mostly black; propodeal dorsum with rugose middle sulcus extending to base as triangle (Fig. 10A)............................ Philanthus minor Kohl

- Pronotal collar indistinctly emarginate antero-medially; yellow colour more developed; propodeal dorsum not as above... 9

9. Face between antennal bases and clypeus and along inner eye margin below emargination smooth and shiny, impunctate (Fig. 22A); gastral T 3 with broad whitish yellow band interrupted medially, densely coarsely punctate, each half of fascia containing round black spot (Fig. 22D)......................................................

- Lower face sparsely punctate, interspaces distinctly larger than puncture diameter................................. 11

11. Body entirely yellow (Fig. 11A,C), with thin black streak along upper part of inner eye margin that does not reach emargination (Fig. 11B, D, E); hind femoral venter with short setae; propodeal enclosure smooth, with inconspicuously rugose median sulcus (Fig. 11A, C)..................................................................... Philanthus pallidus Klug

- Black more extensive than above, especially on head and thorax (Fig. 17A); hind femoral venter with long, fine setae; propodeal enclosure with coarsely rugose broad median sulcus, that extends to propodeal foremargin as inverted triangle (similar to that of P. minor) (Fig. 16B)..........................................................
