Diagnosis. Eleven pairs of phyllobranchiate or intermediate gills. Shield about as broad as long; dorsal surface often with irregularly-shaped, weakly calcified areas medially. Cornea weakly to moderately dilated. Fourth segment of antennal peduncle armed with dorsodistal spine. Epistomial spine straight, or absent. Right chela usually with well delimited dorsomesial and dorsolateral margins; often operculate. Left cheliped well calcified, or sometimes weakly calcified on merus and carpus. Ambulatory legs with dactyls curved. Fourth pereopod with propodal rasp consisting of 1 or more rows of ovate corneous scales. Second abdominal somite with left pleuron terminating in small subtriangular lobe. Males usually with weakly to moderately developed paired 1st and 2nd gonopods; 1st gonopods sometimes absent; rarely with 2nd unpaired left pleopod.
Species. Included in this new genus are three taxa previously considered subspecies by De Saint Laurent (1972) that are herein elevated to specific rank, Sympagurus acutus acutus (De Saint Laurent, 1972) , S. a. bicarinatus (De Saint Laurent, 1972) , and S. a. hirsutus (De Saint Laurent, 1972) ; and also S. boletifer (De Saint Laurent, 1972) , S. bougainvillei Lemaitre, 1994 , S. curvispina (De Saint Laurent, 1974), S. diogenes Whitelegge, 1900 , S. hobbiti ( Macpherson, 1983) , S. macrocerus ( Forest, 1955), S. pacificus Edmondson, 1925, S. pilimanus (A. Milne Edwards, 1880), S. rugosus (De Saint Laurent, 1972), S. ruticheles (A. Milne Edwards, 1891) , S. spinimanus ( Balss, 1911), S. tuberculosus (De Saint Laurent, 1972), and S. wallisi Lemaitre, 1994 .
Type species. Sympagurus diogenes Whitelegge, 1900 . Gender: masculine.
Etymology. From the Greek parageios, pertammg to shallow water, and pagourus, crab. The name is in reference to the depth distribution of the type species of the genus, the shallowest so far known of all parapagurids.
