The shell grows to a length of 93 mm. It differs from Lobatus raninus in these characteristics :
- the alation (wing-like outer lip) ends in a single extended lobe (rather than two) beyond the height of the spire
- the shell shows twelve nodules (a swollen knob-like structure) instead of two
- the aperture is yellowish white (instead of red or blue) 
This species is found in the Caribbean Sea along the Isla Margarita, Venezuela, found at depths up to 29 m.

Like other species in the same genus, Lobatus raninus has a robust, somewhat heavy and solid shell, with a distinct stromboid notch. The body whorl is dorsally ornamented by characteristic coarse spiral ridges. The posterior expansion of the flaring outer lip is always lower than the spire.
The color is brownish, with several disperse white spots. Both inner and outer lips are cream or white.
A cladogram based on sequences of nuclear histone H3 gene and mitochondrial cytochrome-c oxidase I (COI) gene showing phylogenetic relationships of (32 analyzed) species in the genus Strombus and Lambis, including Strombus raninus, was proposed by Latiolais et al (2006):
