Williamia!!!!! You are absolutely right. The pleasant point is: I received once a "W. gussonii" that was a Lepetid. And today, I receive a "Iothia fulva" (from Sicily, pretty range extension) that is a Williamia. I love these crossed jokes. Thank you, gentle fellows! This mystery did not survive a long time. I'll try to do better next time. Olivier ×”× ×§ ×ž×™× ×™×¡ a écrit : > I agree with Paolo.
