Sympagurus   – Lemaitre, 1989: 36 (in part, see Remarks).

Oncopagurus Lemaitre, 1996: 194   View Cited Treatment ; Lemaitre, 2000: 217; Davie, 2002: 88; Poore 2004: 282; De Grave et al., 2009: 26; McLaughlin, 2003: 118 (key); Poore, 2004: 281; Asakura et al., 2006: 215; McLaughlin et al., 2007: 307; McLaughlin et al., 2010: 38.

Type species. Eupagurus bicristatus A. Milne-Edwards, 1880   , by original designation. Gender: masculine.

Diagnosis. Eleven pairs of biserial or rarely (1 species: O. elongatus   ) quadriserial phyllobranchiate gills. Shield about as broad as long; dorsal surface usually weakly calcified medially. Corneas usually weakly to moderately dilated, or less frequently reduced or subconical. Fourth segment of antennal peduncle armed with dorsodistal spine. Epistomial spine strongly curved upward (e.g., Fig. 16D View Fig ), rarely bifid ( Fig. 2C View Fig ). Maxillule with internal lobe having long, terminal seta. Right chela operculate, with well delimited dorsolateral margin, or not operculate (1 species: O. conicus Lemaitre, 2006   ) with weakly defined dorsolateral margin. Left cheliped with carpus and palm frequently with weakly calcified areas dorsally. Ambulatory legs with dactyls broadly curved. Fourth pereopod with propodal rasp consisting of 1 row, or rarely 2 rows (1 species: O. stockmani   ), of corneous scales. Second pleonal somite with left pleuron terminating ventrally in small subtriangular lobe. Males with poorly to moderately developed paired first and second gonopods; first gonopods sometimes absent, or if present each with weakly concave distal lobe; second gonopods 1- or 2-segmented, sometimes asymmetric in size and number of segments, or absent on one side. Female usually with vestigial second right pleopod.

Habtitat. Typically found in gastropod shells, occasionally with coelenterates (actinian, zoanthid, or hydractinian) living on the shell.

Distribution. Indian Ocean; western, central, south and eastern Pacific Ocean; western and eastern Atlantic Ocean. Depth: 50–2308 m.

Species. Twenty-four species (see list).

Remarks. In his revision of Parapagurus   sensu lato, Lemaitre (1989) resurrected the genus Sympagurus   for 30 species (with one species divided into three subspecies) that had been assigned to Parapagurus   by de Saint Laurent (1972). Ten of those 30 species were subsequently placed by Lemaitre (1996) in his genus Oncopagurus   .All other taxa assigned by Lemaitre (1989) to Sympagurus   have now been reassigned to other parapagurid genera ( Lemaitre, 1993, 2004a, b, 2013; Osawa, 1995, 1996).
