Abstract: "The Pamphagidae (Orthoptera, grasshopper) from East Algeria and description of a new species"      
 
Through a 3-year survey of 9 stations in North East of Algeria, we recorded 16 species of grasshopper belonging to the family Pamphagidae. The National Park of Belezma, near Batna city, appears to be the richest region for this family, with 10 species. Notably, Paracinipe sulphuripes, only known from Djelfa, is present at Belezma, showing unexpected relationship between these two areas, separated by 280 km. Within the Pamphagus djelfensis complex, a new species is described, P. batnensis Benkenana & Petit, easily distinguishable by its epiphallic characters. Taking into account several studies dealing with other Algerian stations, we provide certain climatic constraints of most species, as illustrated by bioclimagrams. We show that the semi-arid stage with fresh winter and sub-humid stage with cold winter correspond to the most suitable conditions for this family.
