DISTRIBUTION. — Western Pacific Ocean from Korea and Japan (see Sakai 1976) to the Philippine Is ( Rathbun 1914; Serène & Vadon 1981) and now from Indonesia (Makassar Strait, Tanimbar and Kai islands), Solomon Islands, Vanuatu, New Caledonia, and questionably from French Polynesia. Depth: 80- 512 m. Specimens were also obtained from tangle nets of local fishermen in the Philippines that obtained material estimated to be at least 50 m.

COLOUR

A photograph of freshly collected female specimen from the Solomon Is ( MNHN-B 29204) showed red orange to red reticulations and dots on the carapace and red dots on the chelipeds, similar to those illustrated by Sakai (1976: pl. 188, fig. 1) and Miyake (1991: pl. 50, fig. 3) from Japan, and Ho et al. (2004: fig. 6D) from Taiwan. Colour photographs of freshly collected specimens from the Philippine Is (PANGLAO 2005) confirm this colour pattern.

REMARKS

The abundant material from Taiwan to New Caledonia that was examined agrees well with the female holotype of Goneplax renoculis . Diagnostic characters of the species is an acute, anteriorly curved, anterolateral tooth that is in a straight line below the base of the similarly acute and anteriorly curved but longer outer orbital tooth ( Fig. 28B ). The anterolateral tooth emerges after a short, straight portion of the anterolateral border of the carapace. Also diagnostic is a small tooth on the dorsal, distal end of the merus of each ambulatory leg (P2-P5) ( Fig. 28B ). The propodi of the P5 may have some sparse setae but are not fringed by them.The carapace front is deflexed, and the eye peduncle is 1.2-1.3 of the front width. The eyes are strongly reniform. Large males have two slightly raised horizontal ridges across the width of the carapace.

The G1 is stout, short, and with a truncate tip ( Chen 1998: fig. 11-4, as Goneplax renoculis ). The G2 is slightly shorter than the G1, with the flagellum shorter than the basal part, and a pointed tip. The vulva of mature females extends from the margin of suture 5/6 to the margin of suture 6/7. It is covered by a large, salient, globular vulvar cover that leaves a large, semi-circular anterolateral opening. Suture 6/7 ends at the vulva, leaving a large, flat area between suture 5/6 and complete suture 6/7 that connects directly with the anterior portion of the thoracic sternum.

No specimens from Japan could be examined during this study. The anterolateral teeth of Japanese specimens illustrated by Sakai (1935: pl. 54, fig. 4; 1939: pl. 67, fig. 4; 1965: pl. 84, fig. 2; 1976: pl. 188, fig. 1, as G. renoculis ) are close to each other very much as in Goneplacoides marivenae n. comb. ( Fig. 28A ), which is found in Japan, instead of being separated by a straight margin as in N. renoculis n. comb. ( Fig. 28B ). The meri of the ambulatory legs (P2-P5) of Sakai’s specimens, however, were each armed with a distal tooth unlike the smooth meri of G. marivenae n. comb. ( Fig. 28A ). The colour of Sakai’s illustration ( Sakai 1976: pl. 188, fig. 1, as Goneplax renoculis ) does

A C D

agree with the photograph of a freshly collected specimen from the Solomon Is (see below). The G1 of a small specimen (cl 5.2 mm, cw 7.3 mm; maximum size of males: cl 11.3 mm, cw 17.2 mm; maximum size of females: cl 10.1 mm, cw 16.0 mm) illustrated by Takeda & Miyake (1968: fig. 8c, d, as G. renoculis ) had a spade-like tip different from almost all specimens examined during this study and that illustrated by Chen (1998). The only exception was the G1 of a pre-adult male from the Kai Is, Indonesia (cl 4.0 mm, cw 5.0 mm, MNHN-B 29213), which was similar to that illustrated by Takeda & Miyake (1968).

An incomplete specimen from the Austral Is, French Polynesia (male, cl 9.8, cw 16.7 mm; MNHN-B 29780), the only one from French Polynesia examined, had a carapace, eye peduncles, and P2-P4 (P5 missing) similar to those of N. renoculis n. comb. The only cheliped remaining, however, had an unusually high pollex, and the G1 had a conspicuously pointed tip. It may represent a new species.
