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 1700 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 dry as, 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. Source

Study of rough notes and sketches made by D.C. Geijskes in 1972 and the recently found original drawings by E. de Selys Longchamps done in 1884 from the male syntype of Neoneura bilinearis Selys, 1860, shows the syntype male and female (now lost for several decades) of N. bilinearis refer to the same species later described as Neoneura gaida Rácenis, 1953. Therefore N. gaida is considered a junior synonym of N. bilinearis Selys, 1860. A neotype is chosen for the true N. bilinearis (neotype ♂, Suriname, Kabalebo, 15 viii 1965, in RMNH). N. bilinearis sensu Williamson (1917) is redescribed as Neoneura confundens sp. nov. (holotype ♂, Suriname, Jodensavanna, Koela-kreek, 13 ii 1946, in RMNH). N. confundens has a wide distribution in South America north of the Tropic of Capricorn, but it is lacking from the central and lower Amazon. It occurs in several color morphs and also varies in male appendage, genital ligula, and female pronotum morphology. Copyright © 2013 Magnolia Press. Source
