Scopimera globosa (De Haan, 1835)

? Scopimera globosa — Koelbel 1897: 713; Gee 1926: 165 [list]; Gordon 1931: 528; Shen 1940a: 233; Morton 1976: 102; Morton and Morton 1983: 185, fig. 10.3(6); Choi 1992: 901.

Taxonomy: Shen (1932b), Sakai (1939), Wong et al. (2010a).

Ty p e: L e c t o t y p e ò i n R M N H D 2 8 2 a n d paralectotypes in RMNH (designated by Yamaguchi and Baba 1993; see also Fransen et al. 1997).

Type locality: Japan, locality unspecified.

Distribution: East China: coasts of China, Korea and Japan ( Sakai 1976).

Habitat: Intertidal; in burrows on slightly exposed sandflats of fine substrates.

Remarks: The present species had been recorded in Hong Kong by Koelbel (1897) and several authors (see above). Shen (1935), when comparing local material against that from Japan, concluded the past local records instead represented S. tuberculata Stimpson, 1858 . The species S. tuberculata had been considered a junior synonym of S. globosa since Koelbel (1897) (see also Sakai 1939). Intriguingly enough, in his checklist of the local brachyuran fauna, under Scopimera, Shen (1940a) listed both S. globosa and S. tuberculata . The record of S. tuberculata by Shen, however, represents S. intermedia Balss, 1934 instead (see Remarks of Scopimera intermedia below). For Shen’s (1940a) record of S. globosa , despite the absence of reliable local material reported or examined in recent decades, and the published literature suggesting it is only reliably known in North China, Korea and Japan ( Shih et al. 2015), there remains the possibility that this temperate species had distributed as far south as Hong Kong in past decades ( Hui and Wong 2019). As such, it is provisionally retained in the fauna of Hong Kong, albeit with doubt. Older records of this species, probably not readily verifiable, are retained as above.

Scopimera intermedia Balss, 1934 #

Scopimera tuberculata — Shen 1935: 36, text-figs. 14, 15; Shen 1940a: 233.

Scopimera intermedia — Hill et al. 1975: 65; 1978: 92; Morton 1979a: 118; Hill and Phillipps 1981: 152, pl. 51b; Morton and Morton 1983: 153, fig. 9.4(4, 5); Shea 1992: tab. 2; KJH Wong et al. 2010a: 48, figs. 1c, d, 2c, d, 3d–f, 4c, d; Hui and Wong 2019: 522; Bravo et al. 2021: tab. 2.

Scopimera globosa — BKK Chan 2001: 24; BKK Chan and Caley 2003: 88, 3 unnumb. figs.; Fong et al. 2005: 54, 2 unnumb. figs [upper and lower left only].

Taxonomy: Serène and Moosa (1981), Wong et al. (2010a), Shih et al. (2015).

Type: Whereabouts and status unknown.

Type locality: Johore, Peninsular Malaysia.

Distribution: Southeast and East Asia: Indonesia, Peninsular Malaysia, Borneo, Vietnam, South China and Taiwan.

Habitat: Intertidal; in burrows on sandflats, substrates of coarser sand, or somewhat gritty.

Remarks: Scopimera tuberculata Stimpson, 1858 (type locality Shimoda, Japan) has long been regarded as junior synonym of S. globosa De Haan, 1835 (since Koelbel 1897). Shen’s (1935) local record of S. tuberculata , provided with rather precise illustrations (and his comparison with Japanese material of S. globosa ), matches with material of S. intermedia we collected from Hong Kong, western Taiwan and Singapore (the latter proximal to type locality, Johore; Wong et al. 2010a).
