Distribution of Stenasellidae in Africa and description of a new species of Metastenasellus from Cameroonian groundwaters

During recent investigations of the groundwater fauna of Cameroon, specimens of a new species of the stygobitic genus Metastenasellus, M. boutini sp. nov. were collected in wells of the city of Douala. The new species can be easily distinguished from the other species of the genus by its relatively...
