    Heliographic signalling in Haploglenius Burmeister, 1839 (Neuroptera Ascalaphidae)

    ABSTRACT
    The males of the ascalaphid genus Haploglenius are equipped with a movable pronotal flap, covering a white thoracic membrane, whose function remains poorly known. Few recent original observations, conducted on undisturbed specimens in their natural environment, suggest that this structure is part of a complex visual communication system based on intermittently showing the bright, reflecting, thoracic white area on a dark background. This behaviour is probably associated with courtship.

    Ascalaphus festivus (Rambur, 1842) in Sardinia, a new genus of Ascalaphidae for Europe (Neuroptera)

    ABSTRACT
    Ascalaphus festivus (Rambur, 1842), a widespread polytypic species in Africa and Middle East, was collected for the first time in southern Sardinia in the 1990s in two independent occasions. Subsequent specific surveys proved the existence of a stable breeding population in at least one coastal locality of Sardinia, thus allowing to fully consider this genus a member of the European fauna.
