Superfamily Grapsoidea Macleay, 1838 Family Grapsidae Macleay, 1838

Grapsus albolineatus Latreille , in Milbert, 1812 #

Grapsus strigosus View in CoL — Stimpson 1858b: 102; Stimpson 1907: 118; Gee 1926: 164 [list]; Gordon 1931: 528; Shen 1940a: 238.

Grapsus longipes Stimpson, 1858b: 102 View in CoL ; Stimpson 1907: 119.

Grapsus albolineatus View in CoL — Banerjee 1960: 147, figs. 1c, 2o, p, 3a, f; Hill et al. 1975: 54; Morton 1976: 97; Hill et al. 1978: 76; Morton 1979a: 112, fig. 6.12; Hill and Phillipps 1981: 148, pl. 50b; Morton and Morton 1983: 42, fig. 4.4(2); Morton and Harper 1995: 51, figs. 7(9), 9(2); Williams 2003: 92, 2 unnumb. figs.; VCS Lai et al. 2006: 55, 3 unnumb. figs.

Taxonomy: Sakai (1939: as G. strigosus View in CoL ), Banerjee (1960), Crosnier (1965), Holthuis (1977).

Type: Syntypes probably in MNHN: status unknown ( Holthuis 1977).

Type locality: Mauritius (as l’Ile-de-France).

Distribution: Western Indian Ocean to Central Pacific: from South Africa, Red Sea to Suez, Arabian Sea and Bay of Bengal, Southeast to East Asia reaching Japan, northern Australia, and east to Samoa and Hawaii ( Banerjee 1960).

Habitat: Intertidal and shallow subtidal; agile herbivores on rocky shores.

Remarks: The species G. longipes Stimpson, 1858 has long been considered synonymous with G. strigosus (Herbst, 1799) by Rathbun (in Stimpson 1907) and Sakai (1939). The name Cancer strigosus Herbst, 1799 , however, is a homonym of Cancer strigosus Linnaeus, 1761 (now Galathea strigosus , an Atlantic squat lobster; see Ahyong et al. 2017). Banerjee (1960) showed that the next available name being Grapsus albolineatus Lamarck, 1818 . This name was established as “ Grapse albolineata ” by Latreille in Milbert, 1812, thus senior to Lamarck’s species (Ng et al. 2008).

Metopograpsus frontalis Miers, 1880 View in CoL #

Metopograpsus frontalis View in CoL — Morton and Morton 1983: 93, fig. 7.3(2); VCS Lai et al. 2006: 56, 2 unnumb. figs.; Bravo et al. 2021: tab. 2.

Metopograpsus latifrons View in CoL — Tam and Wong 2000: 115, 2 unnumb. figs. [not Grapsus latifrons White, 1847 View in CoL ].

Taxonomy: Tweedie (1949: as gracilipes View in CoL ),

Banerjee (1960).

Type: Lectotype ò NHM 1880.6 (designated by Banerjee 1960).

Type locality: Celebes, Makassar, Indonesia.

Distribution: Eastern Indian Ocean to West Pacific: Sri Lanka, Singapore, South China, Indonesia, Australia and New Guinea ( Banerjee 1960; Yang et al. 2008).

Habitat: Intertidal; under rock fragments along gravelly shores, often associated with freshwater discharge, sometimes under mangroves.

Remarks: In reporting “ M. messor ” from Hong Kong, Shen (1940a) cited the treatment of M. messor in De Man (1888b) , which was later described as M. messor var. gracilipes by De Man (1891). Banerjee (1960) later showed that M. gracilipes De Man, 1891 is a junior synonym of M. frontalis Miers, 1880 .
