Key to species of Philanthinus View in CoL View at ENA and Philanthus recorded from Egypt.

1. Inner eye margins simple, slightly concave and greatly bowed away from each other ( Fig. 3C View FIGURE 3 ); pronotal collar distinctly reduced, depressed and appressed to mesoscutum ( Fig. 3A View FIGURE 3 ) (genus Philanthinus View in CoL )....... Philanthinus integer de Beaumont View in CoL

- Inner eye margins distinctly emarginate (as in Fig. 4B); pronotal collar well-developed (Fig. 4D) (genus Philanthus View in CoL )...... 2

2. Dorsal surface of propodeum entirely, densely punctate ( Fig. 18D View FIGURE 18 ); apical margin of clypeus with two median teeth in female, and three in male................................................. Philanthus triangulum abdelcader Lepeletier View in CoL

- Dorsal surface of propodeum at least partly smooth and shiny; apical margin of clypeus without teeth.................. 3

3. Propodeal dorsum with broad median rugose sulcus, lateral side of sulcus shiny, with some points; head and thorax with long whitish pilosity masking some parts ( Fig. 14C View FIGURE 14 ); mesopleuron less shiny ( Fig. 14C View FIGURE 14 ); male clypeal moustache dense, nearly meeting medially ( Fig. 14B View FIGURE 14 ); thorax entirely black ( Fig. 14C View FIGURE 14 ).............................. Philanthus rutilus Spinola View in CoL

- Propodeal dorsum smooth and shiny, with or without shagreened median sulcus; head and thorax without long pilosity; mesopleuron shiny; male clypeal moustache either meeting or not meeting medially; thorax with some yellow........... 4

4. Malar space conspicuously long ( Fig. 8D View FIGURE 8 ), as long as 2/3 F 1 in male and half length of F 1 in female; body predominantly yellow ( Fig. 7A, B View FIGURE 7 ); gaster with superficial, dense punctures ( Fig. 8E View FIGURE 8 )........................ Philanthus genalis Kohl View in CoL

- Malar space inconspicuous; gaster clearly punctate, punctures sometimes spaced; body colour variable................ 5

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

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

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

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

7. Gastral T 3 yellow or with a continuous or medially interrupted broad yellowish to whitish band like those of T 2 and T 4; T 1 or T 1-3 with ferruginous; T 3 finely punctate................................................................... 8

- Gastral T 3 black, or with very reduced yellow markings ( Fig. 5A, C View FIGURE 5 ), 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 View in CoL

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

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

- Lower face punctate, either sparsely or densely; T 3 differs in colour and sculpture................................. 10

10. Lower face densely punctate (Fig. 4B), interspaces equal to puncture diameter........ Philanthus ammochrysus W. Schulz View in CoL

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

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