	This study investigates the biostratigraphic and paleobiogeographic significance of\&nbsp;Hemipneustes africanus\&nbsp;Deshayes, 1848, with a special attention on its temporal extent and geographical distribution during the Late Cretaceous. The overarching scientific question investigated herein tackles the significance of the distribution and stratigraphic position of this taxon in elucidating its faunal provincialism and dispersal limits within the southern Tethys.



	A newly discovered and well-dated occurrence of\&nbsp;H. africanus\&nbsp;is described in a new area of the Aur{\`e}s Basin, within the Beni Fedhala syncline (Maafa{\textendash}Djebel Gueroun, Algeria). This taxon was found associated with the ammonite index species\&nbsp;Nostoceras\&nbsp;(Bostrychoceras)\&nbsp;polyplocum\&nbsp;(Roemer, 1841), within the Total Range Zone of the planktic foraminifer\&nbsp;Globotruncana calcarata\&nbsp;Cushman, 1927, which indicates a Late Campanian age.



	The present record represents one of the earliest chronostratigraphically constrained reports of the genus\&nbsp;Hemipneustes\&nbsp;in the upper Campanian. The limited geographic distribution of the species, restricted to Algeria, Tunisia and Spain, suggests low dispersal ability, further contributing to our general understanding of the regional faunal differentiation within the southern Tethyan region during the Late Cretaceous.
