Material examined. See Shih et al. (2012) for specimens examined from Taiwan (including Penghu and Dongsha) and the Ryukyus.

Distribution. Western Pacific ( Japan [including Ryukyus], Taiwan [including Penghu and Dongsha], Philippines, New Guinea, Australia), Central and South Pacific, and eastern Indian Ocean ( Thailand).

Remarks. Shih et al. (2012) separated U. splendida ( Stimpson, 1858) from U. crassipes and some old records U. crassipes have been revised (see Remarks under U. splendida ).

Parisi (1918) recorded U. crassipes (as U. pulchella (Stimpson, 1858)) from Misaki, Japan. Kudo & Yamada (2000) also mentioned a record from Wakayama, based on the communication with Dr. K. Wada. Uca crassipes is common in the Ryukyus. The record from “Tokaito coast: Oho Sima” deposited in the U.S. National Museum of Natural History, Washington DC, USA (USNM 22288) ( Crane 1975) should be the island of Amami Oshima, in the central Ryukyus.

Previously the species from Ogasawara Islands has been identified as either U. lactea , U. pulchella , U. annulipes (H. Milne Edwards, 1837) or U. crassipes (see Shih et al. 2013), which was established as an endemic species, Uca (Paraleptuca) boninensis Shih, Komai & Liu, 2013 . This species is similar to U. crassipes , but has a moderately acute and produced anteriorly anterolateral angles, and longer anterolateral margins (compared to U. crassipes with anterolateral angles strongly acute, produced anterolaterally, anterolateral margins short or absent) and a relatively stouter G1 ( Shih et al. 2013).
