Inproceedings Reference Biodiversity of the freshwater crabs of Benin (Potamonautidae): a genetic approach
Introduction: Published reports on freshwater crabs in Benin (West Africa) are very scarce and mention only two accepted taxa: Sudanonautes aubryi and S. monodi (the latter with no precise locality). The inventory of these species (described using specimens from Gabon and Cameroon, respectively) is still poorly known. Methods: Here, we explore the diversity of freshwater crabs in Benin using a selection of 18 specimens collected in 2022 and 2023 in a range of aquatic biotopes and throughout the country, except for the far north. The specimens were examined morphologically and sequenced for fragments of the COI, 16S and H3 genes. Results: Despite a general variability in color, shape, size and in the DNA sequences (proportion of substitution per site up to ca. 8% for COI, 3% for 16S and 0.3% for H3), our results suggest that all the Beninese crabs belong to a single species of the Sudanonautes genus. They also show that they are neither S. aubryi nor S. floweri, with which they show consistent morphological differences and larger proportions of substitution per site at COI (>10%), 16S (>6%) and H3 (>0.6%). Conclusions: The Beninese crabs may belong to an undescribed species. However, they are more likely conspecific with S. pelii, a species described from the coastal plain of Ghana, previously considered to be a junior synonym of S. aubryi, and whose lectotype’s photographs show no obvious morphological differences with the Sudanonautes crabs from Benin. It is therefore likely that S. pelii will have to be revalidated for certain populations of Sudanonautes crabs from Ghana, Benin and probably adjacent countries.

Inproceedings Reference Bioerosional marks in the shells of two extinct sea turtle taxa from the Eocene of Belgium
Bioerosional marks are frequently recognized as indicators of the dynamic interactions between the organisms and their surrounding environments. In the fossil record, these structures are frequently manifest in the skeletal remains of vertebrates, being commonly associated to predation activity, scavenging, or post-mortem degradation processes. In the case of the turtles, their shells offer a distinctive substrate, exposed for the development of bioerosional processes throughout the organism life, unlike other vertebrate osseous structures. These bioerosions can indicate the type of habitat in which the turtles live, their behavioral patterns, and even their state of health. Sea turtles, as other marine vertebrates, have been extensively studied in the realms of the biology, evolution, and conservation. However, relatively scarce information is available regarding the pathologies and infectious diseases affecting their shells, especially when extinct taxa are analyzed. The aim of this study is to analyze the diverse types of bioerosional marks on the shells of two sea turtle individuals, attributable to taxa, from the Lutetian (middle Eocene) of Belgium. One of them corresponds to the shell of the holotype of Eochelone brabantica (IRSNB R 0001). Its carapace exhibits multiple erosive anomalies on several costal plates. The second specimen is a carapace of Puppigerus camperi (IRSNB R 0004). It displays different typologies of shell deviations, also of erosive character. The analyses of these specimens have been performed through both the detailed macroscopic examination and the study of the cross-sectional images provided by CT scanning in the case of Eochelone brabantica, and a 3D model obtained through a surface scanner for Puppigerus camperi. As a result, insights into the shell modifications of these two turtle individuals induced by various external agents have been provided, enhancing our understanding of the physical stressors affecting these organisms in ancient marine environments and the organisms responsible for these changes.
