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 ).
