Lygodactylus is the most speciose gekkonid group in Africa, with several additional, candidate species already identified from previous studies. However, in mainland Africa, several groups remain only partially resolved, and there are several taxonomic inconsistencies. Lygodactylus gutturalis was described from Guinea-Bissau in the 1870s and since then, the species has been recorded from West to East Africa, and it is widely distributed through different biomes and ecoregions. However, this taxon has never been studied in detail. In this work, we use an integrative approach, including molecular phylogenetic analysis, morphometrics, skull osteology, and biogeography to provide the first systematic revision of the L. gutturalis species complex. The L. gutturalis complex is a subgroup within the L. picturatus group and includes nine well-differentiated species. We elevate Lygodactylus gutturalis dysmicus to full species status, recognize Lygodactylus depressus as the sister species to L. gutturalis , describe five new species (Lygodactylus kibera sp. nov. , Lygodactylus karamoja sp. nov. , Lygodactylus mirabundus sp. nov. , Lygodactylus leopardinus sp. nov. and Lygodactylus gamblei sp. nov.), and propose an additional candidate species that requires further research. Also, in order to shed light on some taxonomic inconsistencies between the L. gutturalis and Lygodactylus angularis groups, we revisit the L. angularis group, within which we elevate Lygodactylus angularis heeneni and Lygodactylus angularis paurospilus to full species status. The L. gutturalis subgroup diversified during the Late Miocene (between 5–15 Mya), probably as a consequence of multiple vicariant events driven by the expansion of the African savannahs and the establishment of climatic refugia.
