Taxonomic notes. Bolivar (1914) extended the original distribution of A. abjecta Cyrillo, 1787 to North Africa after including a population of Morocco and describing it as the subspecies A. a. africana. In 1931 Uvarov described A. maroccana as a separate species using a female holotype with rounded eyes different from the conical ones typical of A. abjecta; however, Morales Agacino (1948) considered it as a subspecies of A. abjecta, renaming it as Ameles abjecta maroccana and he described the male allotype. He described it with long wings (20 mm, 4.4 times longer than pronotum), however he did not report other measurements of other type specimens which, as we observed, show much shorter flight organs compared to the allotype. This species however exhibits different eye (the main character cited by both Uvarov and Morales Agacino to separate it from A. abjecta) and pronotum shape, which lead Badih & Ruiz (1998) to support the validity of Ameles maroccana as a separate species, citing three males as macropterous in opposition to the brachypterous females. Summarizing, Ameles maroccana is here confirmed as valid and distinct because of the characters outlined above and its marked tendency for wing reduction.

Diagnosis. Similar to A. spallanzania but wings are shorter, not reaching the terminalia, and rounded eyes lacking an apical tubercle (present in A. spallanzania). Similar to A. s. obscura but with hyaline hind wings and sinuous pseudophallus (Fig. 5), as opposed to the infumated hind wings and straight pseudophallus of A. s. obscura.

Remarks. Most of the specimens we measured are from the type series and from the collection of the MNCN, already studied and cited by Morales Agacino (1948). The variability of forewings when related to the pronotum length is here remarkable (26% between min-max in the TL/PL ratio) especially if compared with the other species of Ameles and presents both the short-winged morph with forewings not reaching the terminalia (Fig. 6) and the long winged one covering them. The length of the forewings and their ratio with the pronotum remain however well distinct from the higher values of A. spallanzania (Table 1). On the contrary, we did not notice any evident variability in ocelli size, which remain always very small when compared with other fully-winged species.
