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

Distribution. East China Sea, Taiwan, South China Sea; Japan; Bay of Bengal; Andaman Sea; Gulf of Thailand; northern Australia; Singapore; Malaysia; 10– 90 m.

Habitat. Sandy-mud, frequently occupying shells of the gastropod Polinices .

Remarks. Spiropagurus spiriger is easily recognized by the dorsal surface of the ocular peduncles bearing several short transverse rows of setae. The character of the present materials generally agrees with the original description. However, the chelipeds of only one of all the specimens is asymmetrical (the left cheliped is prominent larger than the right cheliped). The asymmetrical is abnormal for this genus, and all the other characters are similar to those of other specimens. Therefore, this should be considered variation in this species. The maximum shield length of S. spiriger was reported as 7.80 mm ( McLaughlin et al. 2007), but the present materials have expand the range to 9.00 mm. Additionally, some specimens with the median cleft of the telson only bearing one spine were found in the present materials. However, the specimens are smaller (SL not longer than 4.5 mm) and the sexual tube of the males are not well developed. We believe these specimens are juveniles.
