| Character | Variability (intra- and/or interpopulation) | Intra | Inter |
| color of antenna | from black to brown | + | - |
| length of basoflagellomere | 1.7-2.2 times as long as wide | + | + shorter in Balkans populations (1.7-1.9) |
| position of antennal fossette in male | dorsal to lateral or dorsal and medial (Fig. 3) | + | + Iberian populations with medial fossette |

| color of pile on metafemur in male | all yellowish to whitish or with many black in apical one third | + | + some Iberian populations with only pale pile |
| length of pile on metafemur in male | one third to one fifth of width of metafemur | + | + in eastern populations (southern Russia to Siberia) longer, from one third to one fourth of width of metafemur |
| color of knees, apex of tibiae and tarsi | from black to brown | + | - |
| lateral maculae on tergum 2 | distinct, indistinct, to almost absent | + | - |
| pile on terga 3-4 in male | from all pale yellow to many black | + | + Balkans populations with more black pile |
| microtrichose vittae on frons in female | from narrow unconnected to broad and connected near ocellar triangle | + | - |
| color of pile on frons in female | almost all black to mostly whitish | + | - |
| male genitalia | the shape of surstyle and size of area covered with dense short marginal setulae on anterior surstyle lobe (Figs 1, 6) | + | + in eastern populations (southern Russia to Siberia) basolateral protrusion less distinct (Fig. 6G) |
