DISTRIBUTION. — Indian Ocean from South Africa and Madagascar to Western Australia and western Pacific Ocean from Japan to as far east as Tonga ( Fig. 13 ). It is here recorded from Madagascar, Western Australia, Vanuatu, New Caledonia, Loyalty Islands, Fiji, and Tonga for the first time. Depth: 30-731 m.

DIAGNOSIS. — Dorsal surface of gastric region of carapace topped by spine ( Fig. 12 ). Gastric region short, length less than 0.35 carapace length. Supraocular spines shorter than ocular peduncles. Hepatic swellings not topped by tubercle or spine. Merus of each third maxilliped without tubercle or spine on ventral surface ( Fig. 3D ). Abdomen of adult males with all somites distinct; middorsal protuberance on

somite 1, acute spine on somite 2 ( Fig. 12 ). Abdomen of adult females with middorsal protuberance on somite 1, acute spine on each somite 2, 4; somites 4-6 broad and fused with proximal spines laterally near articulation with somite 3. Propodus of each last pair of walking appendage (P5) shorter than carpus; dactylus trailing, not forming subchela ( Fig. 12 ); distal portion of propodus without spinules.

Colour: Live or freshly fixed specimens with transparent to yellowish carapace that is covered with irregular red spots and lines ( Fig. 14 D-F) ( Sakai 1976: pl. 16; Gosliner et al. 1996: 235; Minemizu 2000: 186; Debelius 2001: 258). A wider and complete red line along the posterior border of carapace and along each abdominal somite in both sexes. Cornea of eyes dark brown. Chelipeds and pereopods transparent with narrow, vertical red bands.

REMARKS

Specimens of L. valida showed a relatively small morphological variation throughout its wide geographical range. An exception was a male from Madagascar (MNHN-B 9790), at the southwestern limit of its distribution, which had a reduced dorsal spine and relatively long pereopods.

Size

Maximum size: ♂ 16.0 × 11.5 mm ( Sakai 1976), ♀ cl 17.9 mm ( Williams 1982).
