Incultus tuberculosus (A. Milne-Edwards, 1861) View in CoL

Neptunus (Hellenus) tuberculatus — Gordon 1931: 527 [not Achelous tuberculatus Stimpson, 1860 View in CoL ].

Neptunus (Hellenus) tuberculosus View in CoL — Shen 1940a: 220.

Taxonomy: Crosnier (1962: as Portunus View in CoL ), Stephenson and Rees (1967: as Portunus View in CoL ), Apel and Spiridonov (1998: as Portunus View in CoL ), Yang et al. (2012: as Portunus View in CoL ), Koch et al. (2022).

Type: Holotype ò MNHN B.6073 ( Apel and Spiridonov 1998).

Type locality: Hawaii Islands (as Iles Sandwich), yet probably erroneous ( Castro 2011).

Distribution: Western Indian Ocean to Central Pacific: from Madagascar, East Africa, Gulf of Aden, Gulf of Oman, Phuket ( Thailand), South China Sea, to Palau, Indonesia, Australia, towards Hawaii ( Stephenson 1972a; Apel and Spiridonov 1998); record from Hawaii remains doubtful ( Castro 2011).

Habitat: Subtidal; substrates of soft mud, sandy mud, muddy sand or shell fragments; depths 21 to 580 m ( Yang et al. 2012).

Remarks: Gordon’s (1931) record of “ N. (H.) tuberculatus ” citing “A. M.-Edw.” (contrasting Acheloüs tuberculatus Stimpson, 1860 , an East Pacific species; see Garth and Stephenson (1966)), is probably erroneous, and actually belongs to the present species. Another record of this species from “ China Sea, vicinity Hong Kong ” at 21°53'N, 115°51'E, collection of the Albatross Philippine Expedition (1907–1910), was reported by Stephenson and Rees (1967: p. 52).
