Gloripallium pallium ( Linnaeus, 1758)

Ostrea pallium Linnaeus, 1758: 697 , n° 163. — Dijkstra 1999: 405, figs 2E, F, 3A, B (lectotype).

MATERIAL EXAMINED. — Indonesia. Maluku, lectotype spm ( LSL), designated by Dijkstra (1999: 405). Society Islands . Tarasoc, stn DW 3413, 16˚34’S, 151˚46’W, 385-486 m, 1 juvenile rv ; stn DW 3429, 16˚43’S, 150˚38’W, 493-540 m, 1 juvenile rv; stn DW 3467, 17˚34’S, 149˚54’W, 800-830 m, 1 juvenile rv.

DISTRIBUTION. — Throughout the tropical shallow waters of the Indo-Pacific (except Red Sea and Hawaiian Islands), southwestern limit Zululand, South Africa ( Dijkstra & Kilburn 2001: 281), southeastern limit French Polynesia (Dijkstra 1989: 15). The present juvenile valves from the Society Islands have been washed down to 385-830 m depth.

REMARKS

The present single juvenile valves are morphologically almost indistinguishable from the type material, although the radial plicae are more tripartite with distinct lamellae on each secondary riblet (weakly tripartite with an undivided lamella on the three secondary riblets in the type material) and more orange-reddish tinted than similar-sized specimens from the western Pacific (basically more variegated in coloration). However, the sculpture and colour of G. pallium are variable and intermediate specimens are observed (MNHN, ZMA).
