Lissoporcellana nakasonei (Miyake, 1978)

Porcellana maculata Miyake, 1957: 75, figs. 1–3 (type locality: Tanabe Bay, Wakayama Prefecture, Japan). [Not Porcellana maculata H. Milne Edwards, 1837 (= Neopetrolisthes maculatus)].

Porcellana nakasonei Miyake, 1978: 28 (list).

Lissoporcellana maculata .— Haig, 1978: 712.

Lissoporcellana nakasonei .— Miyake, 1982: 204 (list), 240 (key).— Osawa, 1998b: 876, figs. 1–3.

Material examined. New Caledonia. Montrouzier, Touho Channel, lagoon, 35 m, commensal with Alcyonacea, 17 Sep. 1993, 1 male CL 3.5 mm.

Remarks. This species was redescribed in detail by Osawa (1998b). Lissoporcellana nakasonei closely resembles L. miyakei Haig, 1981, but differs in having subparallel instead of strongly convex branchial margins of the carapace.

Distribution. This species was recorded only from southern Japan (Izu Islands; Kii Pesinsula, Amakura in Kyushu, Ryukyu Islands) at depths of about 20 m on rocky substrates and in association with alcyonacean octocoral, Dendronephthya nipponica Utinomi and Dendronephthya sp. (Osawa 1998b; Kato & Okuno 2001; Osawa & Fujita 2005). This is the first record of L. nakasonei from outside of Japan and from New Caledonia at the depth of 35 m.
