Taxonomy: Guinot (1976).

Type: Neotype ñ in NHM 1930.12.2 142-143 (designated by Guinot 1976).

Type locality: Hong Kong (neotype).

Distribution: South China: so far reliably from Hong Kong only ( Guinot 1976).

Habitat: Intertidal and shallow subtidal; among fouling, or on sandy or gravelly substrates.

Actaeodes mutatus Guinot, 1976 View in CoL #

Actaeodes areolatus View in CoL — Horikoshi and Takeda 1982: tab. 1.

Taxonomy: Guinot (1976).

Type: Presumably lost (original types of Actaea areolata Dana, 1852 ; see Remarks below).

Type locality: Sulu Sea or Balabac Strait.

Distribution: Eastern Indian Ocean to Central Pacific: Mergui Archilepago, Singapore, Thailand, South China, southern Japan, to northern Australia and French Polynesia ( Odhner 1925; Davie 2002; Iwasa-Arai et al. 2015).

Habitat: Intertidal and subtidal; associated with coral reefs, locally in cracks of dead coral blocks.

Remarks: Based on collections of the USEE, Dana (1852a) described Actaea areolata from Sulu Sea or the Balabac Strait, the Philippines ( Dana 1852a: p. 73; 1852b: p. 162; 1855: pl. 8(1)) and Actaeodes areolatus from Raraka Island, Tuamotu (1852a: p. 77; 1852b: p. 194; 1855: pl. 9(8)). The identity of the Tuamotu species, Actaeodes areolatus Dana, 1852 , however, was not regarded as an Actaeodes sensu stricto by Guinot (1976), then treated as a species inquirenda, and is at present under Actaea , pending further revisions (Ng et al. 2008). The Philippine species ( Actaea areolata Dana, 1852 ) is relatively well understood and was later referred to Actaeodes Dana, 1851 by Guinot (1976). This transfer, however, created a homonymy, and the Philippine taxon received a new name, Actaeodes mutatus . The record of “ Actaea areolata ” in Horikoshi and Takeda (1982) from Hong Kong is here referred to Actaeodes mutatus instead.
