Odontozona fasciata Okuno, 2003: 167 .— Saito & Fujita, 2009: 124.— Goy, 2010: 216. — De Grave & Fransen, 2011: 252.— Anker & Tavares, 2013: 429.— Hendrickx & Ayón-Parente, 2014: 345.

Material examined. Loyalty Islands. Ouvéa, Passe de la Meurthe, 6–10 m, 16.XI.1991, 1 female (MNHN-NA). Measurements (mm). PCL: 6.5; RCL: 10.7; TL: 28.2.

Distribution. Japan, Red Sea, and New Caledonia.

Coloration. The color pattern of this species was given by Okuno (2003). Color notes of the New Caledonian specimen agrees with the type material, except the antennae are banded in white and red and the fourth and fifth pereiopods have white dactyli, propodi and carpi with the meri being red distally whitish proximally and ischia outlined in red.

Remarks. Okuno’s (2003) original description of this species was based on three males and a juvenile. The specimen from New Caledonia is the first female recorded, plus an additional four females examined from Ophir Bay, Gulf of Aquba, Red Sea (RMNH-NS 4034) allowing a discussion of some sexual differences and variation within the species. Females are less spinose than males, especially on the pleomeres as well as lacking the male ventral median spines on the sternites. The scaphocerite of the females is wider distally than that of the males ( Fig. 19 A). Variation in spination elsewhere include 4–6 dorsal, 4–12 ventral rostral spines; 9–15 outer margin scaphocerite spines; 1–4 ventral carpal movable spines on fourth and fifth pereiopods; and outer margins of uropodal exopod and endopod with 6–9, 1–3 teeth respectively. There is also much variation in the spination of the third maxillipeds ( Fig. 19 C).
