Sudanonautes is a genus of terrestrial living crabs from the family of Potamonautidae . The ten species of the genus can be found in and on fresh waters in West and Central Africa.
features
An inter- tooth is located on the anterolateral margin between the epibranchial tooth and the exorbital tooth corner . The postfrontal crista protrudes almost horizontally and is complete, so the lateral ends merge into the anterolateral edges.
The side wall is divided into three parts by two furrows. The mandibular palpi are two-part, the final segment consists of a large oval flap, in three species there is a small but clearly recognizable anterior process at the junction between the segments. A long, feathery gill brush is located on the exopodite of the third maxilliped . The third and fourth sternal furrows are only pronounced as two short notches on the sides of the sternum.
The terminal segment of gonopod 1 is very long, at least two-thirds as long as the subterminal segment. Halfway up it bends outward.
Distribution area
The distribution area of the genus extends from southern West Africa ( Ivory Coast , Ghana , Togo , Benin ) to Southwest Africa (northern Angola ), to the east it extends to southwestern Sudan . The species settle there, from rainforests to tree savannahs to Sudan savannahs , always on or in fresh waters.
