Diagnosis. See re-description in McLaughlin (2002) or McLaughlin et al. (2007).

Distribution. East China Sea, Taiwan, South China Sea; Andaman Sea; Gulf of Thailand; Indian Ocean between Maldives and Cape Comorin; Red Sea; 5–129 m depth, but reported at 1500 m at an Indian Ocean site by Alcock (1905).

Habitat. Sandy-mud, gastropod shells.

Remarks. Spiropagurus profundorum was described as a variety of S. spiriger , but Lewinsohn (1982) later considered it to possibly be a valid species and McLaughlin (2002) elevated it to full specific rank.

Spiropagurus profundorum is easily recognized by the carpus of the cheliped bearing two rows of spines extending along the whole joint. The characters of the present materials generally agree with the original description, but the present material has 1–3 spines on the lateral margin of the telson, which is different from the description of 2 or 3 spines by McLaughlin (2002; also McLaughlin et al. 2007).
