|Abstract||A worldwide systematic review of the genus Anapagurus is presented. In addition to the rediagnoses of the genus and all known species, five new species, A. alboranensis, A. adriaticus, A. vossi, A. atlantidii, and A. congolensis, are described. All 18 species are illustrated and a key to the species is given. Several new diagnostic characters found in the right chelipeds (1- the shape and relative size of the mesial and lateral lobes that flank the dorsoproximal margin of the palm; 2- the shape and relative size of the median sinus of the ventroproximal palmar margin; 3- the shape, armature and relative size of the dorsomesial distal carpal angle; and 4- the shape and extension of both ventrodistal and ventroproximal carpal margins, which determine the relative ventral length); the relative length and setation of the ultimate antennular segment; and the relative length between the right uropodal endopod and the distal protopodal lobe have been used. A number of systematic problems are clarified. Anapagurus pusillus Henderson, 1888 is reinstated. Anapagurus brevicarpus A. Milne Edwards & Bouvier, 1892 is found to be a junior synonym of A. chiroacanthus (Lilljeborg, 1856). Anapagurus acutus and A. marginatus described by A. Milne Edwards & Bouvier, 1893, are excluded from Anapagurus and considered species incertae sedis. Anapagurus drachi Forest, 1966, is removed from Anapagurus, and placed in a new genus, Forestopagurus.|
