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

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.
