Based on the collections made in crop fields in Mostaganem (Algeria), an updated list of the Hybotidae species of Algeria is performed. The species Platypalpus verbekei Grootaert & Chvala, 1992 is here cited for the first time in North Africa. This species has a chromatic variation and a certain clypeus variation respect the European populations which are here detailed. In order to facilitate the recognition of this species it is included in this study a diagnosis (in Catalan) and a redescription (in English) based on the specimens collected from the Algerian population, showing the phenotypic variability of the species present in the two shores of the Mediterranean. In total 27 species distributed in 5 genera are known so far in Algeria, of which 4 are cited only in Algeria. Two species are excluded from the catalogue of the Algerian species giving the reasons for that decision
