Referred material.

CUF - NKNY - B 24 (20 shells; Figs 10 D , 12 P ).

Habitat.

Sublittoral on mainly mud and clay with sand and shells at a depth from 11 to 92 m ( Huber 2015).

Distribution.

Indian Ocean; Indo-West Pacific, from China to Indonesia ( Huber 2015). Records of fossils from the Holocene in Thailand ( Robba et al. 2002).

Record in Thailand.

Gulf of Thailand and Andaman Sea ( Swennen et al. 2001; Nabhitabhata 2009; Wells et al. 2021).

Taxonomic remarks and comparisons.

This species is recognised based on the descriptions and figures in Robba et al. (2002) and Huber (2010), specifically in having strong commarginal ridges in the umbonal area then changing into flat and somewhat imbricate low rugae which are more raised on crossing the postero-dorsal keel. This species often co-occurs with Jupiteria puellata , which has an unsculptured shell ( Robba et al. 2002).

Superorder Pteriomorphia Beurlen, 1944

Order Arcida Stoliczka, 1871

Superfamily Arcoidea Lamarck, 1809
