Distribution: The range of Rotundopotamonautes centres on Uganda, Kenya and Ethiopia, with the border between Kenya and Tanzania serving as the south-eastern boundary line and Sudan and Egypt the northern boundary (Fig. 10E). The distribution also includes the central and northern parts of the Rift Valley around Lakes Tanganyika, Kivu and Victoria and their drainages [D.R. Congo (Nord-Kivu and Ituri provinces), Rwanda, Burundi, Tanzania (Kagoro Province)] and South Sudan (Chace, 1942; Corace et al., 2001; Cumberlidge, 2004, 2009b; Cumberlidge & Dobson 2008; Cumberlidge & Clark, 2010a, b, 2012, 2016, 2017, 2018; Cumberlidge & Meyer, 2010, 2011).
Remarks: The subgenus Rotundopotamonautes of Bott (1955) is raised here to genus rank. This genus is established to accommodate 36 species of Potamonautes from the Nile River Basin, Lake Kivu, Uganda, Kenya, Ethiopia, South Sudan, Sudan and Egypt. Bott (1955) established Po. (Rotundopotamonautes) for seven taxa: Po. loveni (as Po. granviki), Po. infravallatus, Po. semilunaris, Po. emini, Po. loashiensis, Po. berardi and Po. ignestii. Six of these (including Po. berardi) are assigned to this revised genus, with the exception of Po. infravallatus, which is here transferred to Arcopotamonautes. The name Rotundopotamonautes is retained because it includes the type species of the subgenus Po. (Rotundopotamonautes), Thelphusa berardi Audouin, 1826. One of the species included here in Rotundopotamonautes is Potamon (Potamonautes) aloysiisabaudiae Nobili, 1906, from Uganda, the type species of Potamonautes (Lobopotamonautes) Bott, 1955. This latter subgenus is treated here as a junior synonym of Rotundopotamonautes under the rule of priority because Potamon (Potamonautes) lirrangensis Rathbun, 1904, is the senior name. DNA data are available for only six of these species: R. kundudo, R. loveni, R. rukwanzi, R. alluaudi, R. odhneri and R. subukia. The molecular phylogenies group these species together in a well-supported clade within the larger clade for Potamonautes s.s. (Fig. 1B 3; Daniels et al., 2015: fig. 1; Daniels & Klaus, 2018: fig 1; Wood et al., 2019: fig. 1).The other 29 species are included here based on shared morphological characters that conform to the genus diagnosis. For example, all of the species in this distinctive genus have a faint, incomplete postfrontal crest that does not traverse the carapace, reduced or absent exorbital and epibranchial teeth, and a smooth anterolateral margin of the carapace behind the epibranchial tooth.
