The discriminating characters of the genera Microeurydemus Pic, 1938, Microsyagrus Pic, 1952 and Afroeurydemus Selman, 1965 are reevaluated with the examination and redescription of the respective type species (Microeurydemus unimaculatus Pic, 1938, Microsyagrus punctaticollis Zoia, 2019, Afroeurydemus nubiensis (Harold, 1877)). The study of the type species highlighted the incorrect correspondence between the generic characters of Microeurydemus and those considered by various authors, starting from Selman (1965). In fact, Microeurydemus currently includes taxa that are not congruent with the characteristics of the genus itself in its original meaning. For these species, Daccordimolpus n. gen. is described, identifiable with Microeurydemus Auct. (nec Pic, 1938), including the following taxa: D. africanus (Jacoby, 1900) n. comb. for Microeurydemus africanus (Jacoby, 1900), D. hartmanni (Harold, 1877) n. comb. for Eurydemus hartmanni Harold, 1877, D. oculatus oculatus (Chapuis, 1879) n. comb. for Microeurydemus oculatus (Chapuis, 1879), D. oculatus wraniki (Lopatin, 1994) n. comb. and n. stat. for Microeurydemus wraniki Lopatin, 1994, D. oculatus sobrinus (Weise, 1903) n. comb. and n. stat. for Eurydemus sobrinus Weise, 1903, D. adrarensis (Pic, 1942) n. comb. for Microeurydemus adrarensis (Pic, 1942). After examination of the type specimens and further material, the following synonymies and a new combination are also formalized: Microeurydemus fasciolatus (Fairmaire, 1893) = Daccordimolpus oculatus oculatus (Chapuis, 1879) n. syn., Microeurydemus semivittatus (Jacoby, 1899) = Daccordimolpus oculatus oculatus (Chapuis, 1879) n. syn., Microeurydemus airensis (Pic, 1950) = Daccordimolpus adrarensis (Pic, 1942) n. syn., Phascus flavescens (Bryant, 1942) n. comb. for Microeurydemus flavescens (Bryant, 1942). Some misidentifications published in works on the fauna of the Arabian Peninsula have also been verified and corrected. A key for the identification of the species of Daccordimolpus n. gen. and an updated version of the key published by Selman (1965, 1972) for the identification of African genera of Typophorini are also provided.
