Key to concinna -group males

1. Genital capsule with gonocoxae presenting a strong longitudinal ridge along their inner margins, the apex of this ridge forming a rounded 60 o –80 o angle (Figures 19F; H; 20E–F)........................................................... 2

- Genital capsule with gonocoxae presenting a smooth internal margin, without any sign of a longitudinal ridge or carina (Figures 21C–D) ............................................................................................ 4

2. Penis valves bulbous, grossly expanded and filling almost the entire space between the gonostyli (Figure 21E). Restricted to Greece (island of Samos) and a small part of western Turkey on the Aegean coast only (around Kuşadası).................................................................................................. heinrichi Grünwaldt

- Penis valves not greatly expanded laterally, not occupying almost the entire space between the gonostyli (Figures 20F; 21F). Species more widespread.............................................................................. 3

3. In profile view, penis valves relatively long, two times longer than broad (Figures 20E; 21H). In dorsal view, surface of penis valves flattened and somewhat “leathery”, with pattern of latitudinal striations, surface dull (Figure 20F). Southern Balkans across Turkey to Armenia ................................................................. crecca Warncke

- In profile view, penis valves relatively short, clearly less than two times longer than wide (Figure 21G). In dorsal view, surface of penis valves more or less domed, shining with only narrow longitudinal dull strip (Figure 21F). Turkey (predominantly eastern Turkey), the Caucasus, and northern Iran ............................................ tecta Radoszkowski

4. In profile view, penis valves relatively small (Figure 21A). In dorsal view, penis valves apically with the two halves presenting a deep “V-shaped” emargination (Figure 21C). Mediterranean Albania and Greece .................... concinna Smith

- In profile view, penis valves relatively large (Figure 21B). In dorsal view, penis valves apically with the two halves presenting a relatively small and rounded emargination (Figure 21D). Southern Turkey, Syria, Israel ............... paradoxa Friese
