Diagnosis. Shield ( Fig. 25K View Fig ) about as broad as long; rostrum broadly rounded, slightly overeaching lateral projections, with short mid-dorsal ridge; lateral projections broadly subtriangular, usually ending bluntly. Ocular peduncles more than half length of shield, with dorsal row of setae; corneas weakly dilated; ocular acicles subtriangular, terminating in strong spine. Antennular peduncle ( Fig. 25K View Fig ) exceeding distal margin of cornea by entire length of ultimate segment. Antennal peduncle ( Fig. 25K View Fig ) exceeding distal margin of cornea; fourth segment with small spine on dorsolateral didstal angle; second segment with dorsolateral distal angle terminating in strong, simple spine, mesial margin with spine on dorsodistal angle; first segment usually unarmed on lateral face; acicle exceeding distal margin of cornea by about 0.2–0.5 length of acicle, mesial margin armed with 5–7 small spines; flagellum reaching to distal end of right cheliped, with numerous setae <1 to 3 flagellar articles in length. Third maxilliped with crista dentata of about 10–12 teeth, 2 or 3 proximal teeth larger than distal. Right cheliped ( Fig. 25L–N View Fig ) moderately setose, chela operculate; carpus and chela proportions affected by size, large specimens with carpus and chela distinctly longer than broad; dactyl set at strongly oblique angle to longitudinal axis of palm; palm broader than long to longer than broad, lateral and dorsomesial margins well delimited by row of small blunt to sharp spines, mesial face strongly sloping, dorsal surface with irregular rows of small spines medially and scattered small tubercles or spines elsewhere, ventral surface smooth; carpus with dorsolateral margin rounded or sometimes well delimited distally by row of spines, dorsal face with numerous small spines or tubercles. Left cheliped usually with lateral face of carpus weakly calcified; palm with dorsomesial row of small spines; carpus with strong dorsodistal spine and long setae dorsally. Ambulatory legs with dactyls ( Fig. 25O View Fig ) each lacking spinules on ventromesial margin or with row of few (up to 9) inconspicuous corneous spinules; carpus with small, blunt or sharp dorsodistal spine. Anterior lobe of sternite XII (between second ambulatory legs) rounded, setose, with subterminal spine. Fourth pereopod propodal rasp ( Fig. 25P View Fig ) with 1 row of rounded scales at least distally. Fifth pereopod propodal rasp extending to mid-length of segment. Uropods and telson markedly asymmetrical; telson ( Fig. 25Q, R View Fig ) lacking transverse suture, posterior lobes separated by shallow cleft, terminal margin of lobes armed with long, often strongly curved corneous spines (females with more spines, usually arranged in several rows, than males). Male lacking first gonopods; second pair of gonopods ( Fig. 25S View Fig ) weakly developed, asymmetrical (right smallest or obsolete), 1-segmented. Female with vestigial second right pleopod.

Colouration. Unknown.

Habitat. Gastropod shells, frequently with an actinian attached.

Distribution. Eastern Pacific, from off southern California and the Gulf of California, the Gulf of Panamá, to off Boca del Guafo and the Juan Fernández Islands, Chile. In the South Pacific, questionably from the Nazca & Sala-y-Gómez Ridge ( Zhadan, 1997). Depth: 55– 993 m.

Remarks. (See also Oncopagurus crusoei   , new species). There is some confusion as to the type locality of O. haigae   . The type locality given by de Saint Laurent (1972) in her original description as “Golfe de Californie ”, is incorrect. Wicksten (2012) pointed out de Saint Laurent’s mistake and indicated that the type locality was “off Santa Cruz I., California ”. However, the specimen label and AHF records of the type deposited in the LACM indicate that the locality is actually Santa Rosa Island, off Los Angeles.

Oncopagurus haigae   is broadly distributed in the eastern Pacific over an inmense expanse of coastline, from off southern California to nearly 44°S, off Chile. Previous to this study, the southern distribution limit of this species was near 31°S, off Valaparaiso, Chile ( Lemaitre & McLaughlin, 1992). It′ s wide range is therefore extended herein even more, nearly 1300 km to the south   .

Zhadan (1997) reported and briefly discussed, without figures, a damaged male specimen from Nazca & Sala-y- Gómez Ridge as Oncopagurus cf. haigae   , considering only tentatively that the specimen might represent O. haigae   . In their summary of Chilean decapod zoogeography, Retamal & Moyano (2010) repeated Zhadan′ s report. The specimen has not been available for examination, and thus the presence of this species in Nazca & Sala-y-Gómez ridge remains to be confirmed.
