Presently known from tropical and subtropical East Asia and from Victoria, Australia. It is difficult to identify and can be expected to be much more widely distributed, at least in warmer waters.

Distribution
provided by World Register of Marine Species
The species was first recorded from Vietnamese waters and has now been recorded from several locations in the Western Pacific from 40 °N to 40 °S in Australia and Japan, and from localities in Southeast Asia, including Vietnam, Thailand, Malaysia, Indonesia and the Philippines. A record from Turkish waters needs verifications.

Harmful effect
provided by World Register of Marine Species
Production of domoic avid has been confirmed by several methods (Kotaki et al 2000, 2005, 2006, Tan et al 2016). * N. navis-varingica produces domoic acid in amounts similar to highly toxic Pseudo-nitzschia species. * It produces both domoic acid (DA) and the derivatives isodomoic acid A (IA) and B (IB). Strains belong to five different toxin profile types: DA, DA-IB, IB, IA-IB, DA-IA-IB. Trace amounts of other isomers have been found

Identification
provided by World Register of Marine Species
Electron microscopy or molecular sequences are needed for correct identification. * The cell is indented in the middle in girdle view, has a moderately eccentric raphe and a weak longitudinal fold on the valve. Most characteristic is silica ornamentation on the mantle and the wall of the raphe canal as vermiform ridges, and as silica warts on the girdle bands. See Lundholm et al 2000. * Verified sequence of the type strain: LSU rDNA: AF417675 ITS rDNA: KX353679
