The Antoine Senglet collection: a major contribution to the knowledge of the odonates of Morocco from the 1960s (Odonata)

Odonata collected by Antoine Senglet in Morocco from 12.vi. to 13.vii.1967 in 28 localities are deposited in the Museum d'histoire naturelle in Geneva (MHNG, Switzerland). The collection includes 453 imagines of 46 species and 326 exuviae of 24 species, corresponding to 73% of the presently known Moroccan Odonata fauna. It is one of the largest collections of Odonata ever made in Morocco and includes the first known evidence for Erythromma viridulum, Orthetrum brunneum, O. cancellatum, Selysiothemis nigra, and Sympetrum sinaiticum for Morocco. Reproduction is proven by the presence of exuviae for all these species except E. viridulum. The collection, which has remained undocumented for more than half a century, is comparable in scope to the contributions presented by the first two syntheses on the dragonflies of Morocco published by LIEFTINCK (1966) and DUMONT (1972). A chronological check-list of the odonate fauna of Morocco details the increase in knowledge from 1850 to the present day.
