The shell of Neoguraleus sandersonae is small, typically reaching lengths of approximately 5–7 mm.[2] It is characterized by a fusiform shape with a moderately high spire. The sculpture consists of fine axial ribs crossed by spiral lirae, giving the shell a cancellate appearance. The coloration is generally a pale brownish-white, often with subtle darker spiral bands. The aperture is narrow, with a short siphonal canal, and the outer lip is slightly thickened.

Distribution
This species is endemic to New Zealand, primarily found in deep waters off the North Island and South Island.[3] It occurs at depths ranging from 100 to 500 meters, typically on soft substrates such as mud or fine sand.
Habitat
Neoguraleus sandersonae inhabits bathyal zones, preferring environments with stable, low-energy conditions. It is commonly associated with deep-sea benthic communities.
Taxonomy
Neoguraleus sandersonae was first described by Bucknill in 1928.[4] The species belongs to the genus Neoguraleus, which includes several other small deep-sea gastropods native to the New Zealand region. The specific epithet sandersonae honors its discoverer or a related figure, though detailed records are sparse.
