description: Key to species of Philanthinus and Philanthus recorded from Egypt.
1. Inner eye margins simple, slightly concave and greatly bowed away from each other (Fig. 3C); pronotal collar distinctly reduced, depressed and appressed to mesoscutum (Fig. 3A) (genus Philanthinus)....... Philanthinus integer de Beaumont
- Inner eye margins distinctly emarginate (as in Fig. 4B); pronotal collar well-developed (Fig. 4D) (genus Philanthus)...... 2
2. Dorsal surface of propodeum entirely, densely punctate (Fig. 18D); apical margin of clypeus with two median teeth in female, and three in male................................................. Philanthus triangulum abdelcader Lepeletier
- 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); mesopleuron less shiny (Fig. 14C); male clypeal moustache dense, nearly meeting medially (Fig. 14B); thorax entirely black (Fig. 14C).............................. Philanthus rutilus Spinola
- 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), as long as 2/3 F 1 in male and half length of F 1 in female; body predominantly yellow (Fig. 7A, B); gaster with superficial, dense punctures (Fig. 8E)........................ Philanthus genalis Kohl
- Malar space inconspicuous; gaster clearly punctate, punctures sometimes spaced; body colour variable................ 5
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
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), 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)...................................................... 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
- 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).......................................................... Philanthus schulthessi Maidl
