Samenvatting

Nieuwe waarnemingen van Donkere tanglibel (Onychogomphus assimilis) en Rode Korenbout (Libellula

pontica)I in Armenië

De Donkere tanglibel (Onychogomphus assimilis) en de Rode korenbout (Libellula pontica) behoren tot de

zeldzaamste en minst gekende Libellen van Armenië. Kennis over de verspreiding van beide soorten in dit land

die ondertussen al was beperkttot eenpaar vindplaatsen dateren vaneenhalve eeuwgeleden.In dit artikel geven

we een overzicht van de verschillende nieuwe vindplaatsen van beide soorten enbespreken we de problemen in

verband met hun bescherming in Armenië.
