The north-Sahelian region, from 22 ° N latitude to the Mediterranean
coast, is a remarkable biogeographical entity showing a very diverse
mosaic of ecosystems.Its biodiversity is not only important but also
unique, we are only beginning to take into account the insect fauna of
this biological patrimony (Tarrier & Delacre, 2008).
According acceptances 240-245 species of Orthoptera Acridomorpha are
recorded and mapped for Morocco, Algeria, Tunisia and Western Sahara ;
on the understanding that the limits shown on the cartographical
distribution maps in no way prejudge the status of the territories
The only one family Pamphagidae accounts for 82 species of which 90 %
are endemic of the region. Out of 15 species of the genus Euryparyphes
thirteen occur only in the Atlas and the Rif mountains. Many species are
recorded from a very few localities, or even the type locality only.
Systematics and distribution of these species are therefore far from
being satisfactorily known in North West Africa (Defaut, 1987a ; Song,
The classification of Acridoidea (Acridomorpha group) has been
substantially revised since Dirsh (1961 and 1965) and Jago (1971).
Families and subfamilies generally used to day are those of Orthoptera
(Rowell & Flook, 1998 ; Eades et
2011) The structure of male genitalia and phylogenetic
analysis led Song & Marino-Perez (2013) and Song et
. (2015) to separate the Acridomorpha group into six
monophyletic superfamilies, two of them being present in Northwest
Africa : Pyrgomorphoidea (Pyrgormorphidae) and Acridoidea with four
Families (Pamphagidae, Acrididae, Dericorythidae and Pamphagodidae).
