The genus Cicynethus Simon, 1910 is revised. Apart from the type species C. peringueyi Simon, 1893, only known from a juvenile, it contains five species, all of which are here described or redescribed based on adults: C. acer sp. nov. (♂♀), C. decoratus (Lawrence, 1952) comb. nov (♂), C. floriumfontis Jocqué, 1991 (♂♀), C. mossambicus sp. nov. (♂♀) and C. subtropicalis (Lawrence, 1952) comb. nov. (♂♀). The species are characterized by the genitalia, but also by the colour pattern. The distribution of the genus is extended to northern Mozambique. Cicynethus hongfuchui is transferred to Storenomorpha hongfuchui (Barrion, Barrion-Dupo & Heong, 2013) comb. nov. Cicynethus acanthopus Simon, 1910 is considered a species incertae sedis. A key to the species is provided.
