Thalamita picta Stimpson, 1858 View in CoL

Thalamita picta View in CoL — Thompson and Horikoshi 1982: tab. 1; Thompson et al. 1982: tab. 1; RSS Wu 1982: tab. 1; Morton and Morton 1983: 94, fig. 7.4(1); RSS Wu and Shin 1998: tab. 1.

Taxonomy: Stephenson and Hudson (1957), Crosnier (1962), Garth (1965), Chen (1975), Wee and Ng (1995), Yang et al. (2012).

Type: Presumably lost.

Type locality: Oshima (as Ousima), Japan.

Distribution: Western Indian Ocean to East Pacific: from East Africa, Red Sea, India, Southeast and East Asia to Japan, towards Australia, New Caledonia, Marshall Islands, Hawaii, Tuamotu, Samoa and Clipperton Island.

Habitat: Intertidal and subtidal; in rocky or coral reefs ( Yang et al. 2012).

Remarks: This species is commonly reported associated with corals reefs (see cited works under Taxonomy above). Considering the habitat, some local records appear in need of verification: Thompson and Horikoshi (1982), Thompson et al. (1982), RSS Wu (1982) and RSS Wu and Shin (1998) all reporting material of this species sampled from Tolo Channel (trawled from gravelly benthic substrates).

Taxonomy: Stephenson and Hudson (1957: as Thalamita ), Stephenson (1972b: as Thalamita ), Wee and Ng (1995: as Thalamita ), Yang et al. (2012: as Thalamita ).

Type: Neotype ò NHM 1986.848 (designated by Wee and Ng 1995).

Type locality: Tolo Harbour, Hong Kong (neotype).

Distribution: Western Indian Ocean to West Pacific: from East Africa, Red Sea, India, Southeastand East Asia to Japan, Australia, New Caledonia, Marshall Islands, Fiji and Samoa.

Habitat: Intertidal and subtidal; among rocky reefs, or on substrates of sand or muddy sand.

Remarks: While the species T. danae Stimpson, 1858 and T. stimpsoni A. Milne-Edwards, 1871 are merely distinguished by relative size of the fourth anterolateral tooth (Stephenson and Hudson 1957), the character is regarded as age-dependent, and the decision of synonymizing T. stimpsoni under T. danae as presented in Stephenson (1972b) and Wee and Ng (1995) is followed. Another closely similar species, T. foresti Crosnier, 1962 , was reported by Stephenson and Rees (1967: p. 75) based on material from “Sabtan I., China Sea, vicinity Hong Kong ” collected during the Albatross Philippine Expedition in 1908. The site was probably now Sabtang of the Batanes Islands, recorded to be around 20°46'N, 120°52'E ( US Bureau of Fisheries 1910) within the Luzon Strait, therefore cannot be considered as fauna of Hong Kong.
