Material. Unassigned. Sample was collected from ES.

Abundance. Rare (Only one specimen collected).

Habitat. Rocky shore. Low shore.

Local distribution. ES.

Ecology and conservation. This species seems to prefer slightly muddier habitats, and can often be found on muddy sand and rocks in estuaries, and occasionally in the edges of mangrove forests. It can also be found sympatrically with N. chamaeleon , with which they can be confused with, on rocky shores albeit less commonly.

Biogeographical distribution. BY, SR, JH, AN, VN and SG. Generally distributed in Indo-West Pacific ( Eichhorst 2016a).
