This article seeks to bring new insights on funerary practices of Ngongo Mbata (17-18th cent. AD), a Kongo Kingdom’s major site. The excavation that took place between 1938 and 1942, has delivered a number of tombs. The skeletal assemblage, curated in the Royal Belgian Institute of Natural Sciences, consists of 38 human skeletons. The bones are badly preserved. With the main aim of conducting the biological profile of Ngongo Mbata’s population (estimation of age, sex and stature). This was completed by a more specific study of dental pathologies and morphological variations to enrich this content. Finally, the studied population was placed in a larger geographical context to shed new light on populations in Central Africa. Despite the bad preservation of skeletons, our study has revealed a high presence of young individuals (less than 30 years old). Besides the dental pathological study has shown, a low frequency of dental carious, dental calculus or periodontal diseases, which seems to indicate a relatively good dental health. Beyond the lifestyles, this research has also revealed different aspects of the funerary practices of Kongo’s society. In the future, isotopic, micro-wear or dental metric variations research, could increase our knowledge and open new perspectives on diet, mobility and geographical origin of this population.

In previous studies, the high degree of similarity of some species of Ilyodromus Sars, 1894 (Herpetocypridinae) to species of another subfamily (Isocypridinae) was noted, calling for a revision of their systematic placement. Here, the systematics of Ilyodromus Sars, 1894 are revised within this context by redescribing four species and comparing these to other genera of Herpetocypridinae and Isocypridinae. Material for the four redescribed species (I. amplicolis De Deckker, 1981, I. dikrus De Deckker, 1981, I. candonites De Deckker, 1981, and I. williamsi (McKenzie, 1966)) was obtained from Museum Victoria and recollected topotypes. It was found that most genera within Isocypridinae share morphological characters that are diagnostic of the subfamily Herpetocypridinae. On these grounds, the transfer of Isocypridinae to the rank of Tribe Isocypridini Rome, 1965 of subfamily Herpetocypridinae Kaufmann, 1900 is proposed here to account for the present understanding of morphological similarity.
