Stratigraphic range: Recent

1981: Crania indonesiensis Zezina, 1981, Galathea Report, Ƒolume 15, p. 9, text-fig. 1, pl. 1, fig. 1–3. 1986: Neocrania indonesiensis Zezina, Lee & Brunton, Bull. Nat. Hist. Mus.

Synonymy. Zezina (1981) named species C. indonesiensis based on a single dorsal valve from the Coral Sea. Lee & Brunton (1986) placed Crania indonesiensis in Neocrania and Lee & Brunton (2001) placed it into Novocrania .

Type material and type locality. The type specimen is held in the Zoology Museum, Copenhagen, Denmark (ZMUC-Bra-20). The type locality is the Coral Sea, Indonesia, 7.48°S, 114.81°E (Zezina 1981).

Material examined. The holotype of N. indonesiensis was borrowed from the Zoology Museum, Copenhagen (Table 7).

Description. The valve is small, 6 mm long and 6 wide, and sub-quadrate (Fig. 16J, K). The exterior is hummocky and mottled white and light brown. The muscle scars are white, the posterior adductor muscle scars are sub-round, the anterior adductor slow-muscle scars are reniform, the support structure scars are crescent shaped and the small anterior muscle scars are separated (Fig. 16L).

Ecology. The specimen from Indonesia was collected at 240 m (Zezina 1981).

Remarks. This specimen is similar to dorsal valves of N. huttoni in its colouring and hummocky surface and may be synonymous with that species. Without a ventral valve, and preferably some more specimens, the status of this species cannot be determined. The species N. indonesiensis is retained until more material is available.
