Neotype. USNM 121280 ( Maddocks 1969a).

Type locality. LK-12 Station, Galle, Sri Lanka ( Maddocks 1969a).

Material. 10 specimens (MP-612 and MP-747).

Figured specimens. CP-448, CP-449, CP-450 and CP-453 (carapaces); CP-451 and CP-452 (valves) ( Tab. 2).

Geographic and stratigraphic distribution. Manaar Gulf ( Scott 1905), near Kalpitiya ( Brady 1886) and Galle, Sri Lanka ( Maddocks 1969a); Java, Indonesia ( Whatley & Roberts 1995); Oeno, Pitcairn e Henderson atolls, Pitcairn islands ( Whatley & Roberts 1995; Whatley et al. 2004); Easter Island, Chile ( Whatley & Jones 1999); possibly São Pedro-São Paulo Archipelago, Brazil; Recent.

Remarks. The largest specimen in the present work has a general shape very similar to those in Maddocks (1969a). Although it certainly belongs to the same species-group, its size is somewhat smaller than Neonesidea tenera . It probably corresponds to an A-1 instar of the species. N. manningi Maddocks, 1975 , from Ascension Island, is also similar, but even smaller ( Maddocks 1975). Several species of the N. tenera group present similar carapaces, but distinctive appendices.
