Three new species of the Cameroonian endemic freshwater crab genus Buea Cumberlidge, Mvogo Ndongo, Clark & Daniels, 2019 are described. The new species were collected from protected areas in the Southwest region of Cameroon, the Korup and Bakossi National Parks and the Mt. Nlonako Ecological Reserve. These species are distinguished from each other and from the type species of the genus, Buea asylos (Cumberlidge, 1993), by a combination of morphological characters (carapace, thoracic sternum, chelipeds, and male first gonopod) and by partial sequences of three mitochondrial DNA genes (COI, 12S rRNA, and 16S rRNA). A phylogenetic analysis that included representatives of all other freshwater crab genera found in Cameroon recovered each of the new species as a well-supported distinct lineage. An identification key is also provided for the four species of Buea and the conservation status of the new species is discussed.

A case study of the coconut crab Birgus latro on Zanzibar highlights global threats and conservation solutions

Summary: The coconut crab, the largest terrestrial decapod, is threatened by habitat destruction and overharvesting due to human activities. Research has shown that larger subpopulations are found in areas with crops and away from human activities, while the largest adult coconut crabs are located on more remote islands and in areas where they are not exploited. Protection and remote locations offer hope for the survival of this species, with opportunities for conservation through community involvement and tourism revenue.

Regional climates shape the biogeographic history of a broadly distributed freshwater crab species complex

Boyang Shi, Da Pan, Yufang Sun, Xiaorui Liu, Xiulin Lv, Neil Cumberlidge, Hongying Sun

Summary: This study explores how past regional climatic differences have influenced the biogeographic history of endemic freshwater crabs in China. By studying the Sinopotamon yangtsekiense species complex, researchers found that divergence of crab lineages across the Qinling Mountains-Huaihe River Line was linked to significant past variations in monsoon intensity and the location of multiple refuges. The phylogeographical isolation observed in these crabs today is a result of different populations being isolated in separate refuges during the Last Glacial Maximum.

A new species of the freshwater crab genus Potamonemus Cumberlidge & Clark, 1992 (Crustacea, Potamonautidae) endemic to the forested highlands of southwestern Cameroon, Central Africa

Pierre A. Mvogo Ndongo, Thomas von Rintelen, Neil Cumberlidge

Summary: A new species of freshwater crab genus Potamonemus was described in this study, with distinguishing characteristics of the carapace and chelipeds. Phylogenetic analysis based on mitochondrial DNA genes confirmed the new species as a distinct lineage. The study also compared the new species to existing species of Potamonemus and discussed the conservation status of the genus.

Summary: Paragonimiasis is a neglected disease caused by zoonotic trematodes of Paragonimus spp., particularly in Africa. Recent transmission was found in Southeast Nigeria, Cote d'Ivoire, and Cameroon, with higher prevalence of P. uterobilateralis than P. africanus. More studies are urgently needed to determine the distribution and diversity of Paragonimus species in Africa.

Summary: The taxonomic status of the freshwater crab Sudanonautes granulatus in West and Central Africa has been revised to reveal that it consists of at least 4 species. Diagnoses, illustrations, and distribution maps are provided for these species and compared with congeners in the region.

Summary: The taxonomic status of the freshwater crab Potamonautes lirrangensis sensu lato has been revised to identify four separate species, based on morphological and molecular evidence. These species include P. lirrangensis s. str., P. kisangani sp. nov., P. amosae sp. nov., and P. orbitospinus, each with diagnostic information, illustrations, distribution maps, and comparisons to similar species in Central and Southern Africa.
