Bonjour Prinobius, j'arrive après la bagarre. Merci pour les pdf signalés
A propos des Sténoptères..... , j'ai eu un échange par mail la dessus avec le spécialiste G. Sama il y a quelques temps , et je te fais profiter de la clé qu'il me donnait:
"Cher collègue,
...
Pour
S. adlbaueri, je me permet de douter de la presence de cette espèce en
Syrie; cette espèce est seulement connue de l'extrème partie sud orientale
de la Turquie; votre
adlbaueri est vraisemblablement (?) le vrai
S.
flavicornis qui, repandu jusqu'en Bulgarie, inconnue de la Turquie,
réapparait en Syrie, Jordanie et Israel.
S. adlbaueri a une large bande
basale noire aux
élytres. Je vous repète ci dessous le nouvelles clés, comprenant
S. adlbaueri.
Cordialement.
G.Sama
