The freshwater crabs obtained from the Lanjak-Entimau area in Sarawak, East Malaysia, Borneo, are reported upon. One new genus (Ibanum) and two new species of Potamidae (Ibanum aethes and Isolapotamon stuebingi) and a new species of Grapsidae (Geosesarma katibas) are described. The identity of Potamon (Geothelphusa) bicristatum De Man, 1899, orginally described from the upper Kapuas in Kalimantan is also clarified, and is here assigned to the new genus, Ibanum.
