Abstract
A new species of the freshwater crab genus Potamonautes MacLeay, 1838, is described from Gorongosa National Park in Sofala Province, Mozambique, southern Africa. Potamonautes gorongosa, new species, is morphologically and phylogenetically distinct from the other species of Potamonautes found in Mozambique and nearby countries, and is most closely related to Potamonautes mutareensis Phiri and Daniels, 2013, from eastern Zimbabwe. The new species differs from this species and its other congeners by a unique combination of morphological characters of the first gonopod, the anterior sternum, third maxilliped, and the major cheliped. Illustrations of P. gorongosa new species are provided, and differences with other species found in Mozambique and southeastern Africa are discussed.

Illustrations of P. gorongosa new species are provided, and differences with other species found in Mozambique and southeastern Africa are discussed
The freshwater crab fauna of several countries in southern Africa is poorly known despite a number of recent contributions (Reed and Cumberlidge, 2004; Cumberlidge and Tavares, 2006; Cumberlidge and Daniels, 2007; 2009; Daniels and Bayliss, 2012; Phiri and Daniels, 2013; Daniels et al, 2014; 2015) and some countries, such as Mozambique, have been overlooked until recently when it comes to biological inventories
The specimens reported on here from the Gorongosa National Park have a number of important characters that do not conform to the descriptions of any known African species (Chace, 1953; Bott, 1955; Cumberlidge, 1999; Reed and Cumberlidge 2004, 2006), and proved to belong to a new species of Potamonautes MacLeay, 1838 in the exclusively African freshwater crab family Potamonautidae Bott, 1970
