Distribution: Australia, Western

Australia (Houtman Abrolhos Is);

Queensland, southern Great Barrier

Reef (Heron I.); New Caledonia; coral

rubble, 0–30 m depth.

Remarks: This species is clearly

very different from Coralanthura

endeavourae, a genus and species

described in the same paper by Poore &

Kensley (1981). Their only similarities

are quite superficial; mouthparts, pere­

opods and pleopods are quite different

(Kensley & Poore, 1982).

The species is most similar to E.

amstelodami from which it differs in

shorter endopod of pleopod 1, narrower

telson and broader propodi on pereo­

pods 1 and 2. New material enables the

habitus and male pleopods 1 and 2 to be

figured for the first time, and flagellum

of antenna 1 to be drawn more accu­

rately than in the original description. FIGURE 15. Expanathura ardea (Poore & Ken­ New material extends the distribution sley, 1981). Juvenile, 4.1 mm, QM W16292. Pleopods 1, 2 from male, 3.0 mm, QM W16292.
