Among these, three Pamphaginae Burmeister, 1840, viz. Paracinipe exarata (Bolivar, 1936) , Glauvarovia mendizabali Morales Agacino, 1945 and Glauia saharae Morales Agacino & Descamps, 1968 , were found to be the southernmost of the 83 species of Pamphaginae known from North Africa ( Morales Agacino & Descamps 1968 ; Descamps 1970 ; Chobanov & Massa 2022 ). All the four genera of Dericorythidae known from North Africa are present in the studied area, including one genus represented by a single endemic species, Bolivaremia domenechi Morales Agacino, 1949 . In contrast to the many species originating from the Mediterranean border of Sahara, only three taxa, Anacridium melanorhodon melanorhodon (Walker, 1829) , Poekilocerus bufonius hieroglyphicus (Klug, 1829) and Sphingonotus canariensis Saussure, 1884 , are Sahelian species that extend occasionally to Rio de Oro. Morales Agacino (1945a) collected eight nymphs of Poekilocerus bufonius hieroglyphicus , 1 ♂ and 1 ♀ nymphs (15. IV.1943) at Leglat = Derramán and 6 larvae (14.XII.1941) close to Zug. One of us (AG) observed also one larva at Derramán, west of Aousserd (22°36’N, 14°28’W; 360 m, 19-20. XII.2017). Such breeding, in localities where the obligatory host plant, i.e., Calotropis procera Aïton, 1811 , has not been found, is unlikely to result in fertile population ( Popov & McE Kevan 1979 ). We detailed below some of the questions that the inventories of Morales Agacino could help reanalysing, namely the synonymy between Pamphagulus mateui Morales Agacino, 1949 and Pamphagulus vicinus Ramme, 1931 (Dericorythidae) ; the type locality of Bolivaremia domenechi Morales Agacino, 1949 ; the location of Aserifa, a paratype locality of Bolivaremia domenechi laevigata Morales Agacino, 1949 ; and the extension of the distributions of pamphagid grasshoppers in the Atlantic Sahara as documented by Morales Agacino collections.
