    Abstract

    Several field surveys between 2007 and 2014 were undertaken in Morocco. Altogether
    54 species were observed during our studies, representing 86 % of the odonate fauna of
    the country. Orthetrum sabina is new for Morocco, increasing the number of species to 63. The
    species was found at Oued Ez-Zahar near Akhfenir, about 1 700 km off its nearest known locality
    at Ouargla in Algeria. Two small populations of Erythromma viridulum were found for the
    first time in the Rif, bridging the gap between populations in the Middle Atlas and the Iberian
    Peninsula. The third observation of Sympetrum sinaiticum for Morocco was recorded and we
    were able to significantly increase the known number of localities of the threatened Moroccan
    endemic Cordulegaster princeps. We further can show that several species (e.g., Boyeria irene, Pyrrhosoma nymphula) are more widely distributed than believed and occur also at low altitudes in the country. On the other hand, Calopteryx exul, Calopteryx virgo meridionalis, Lestes dryas, Coenagrion mercuriale, Aeshna isoceles and Libellula quadrimaculata are very rare in Morocco and their populations should be monitored to assess their potential decline. Finally, for
    all Moroccan dragonfly species the first and last observation dates are listed. For 17 of them we provide the earliest observation date and for seven species we prolong the observation period
