The main characteristics of this species are:
♦ height up to 3.2 mm, width up to 2.7 mm;
♦ moderately elevated spire; slightly cyrtoconoidal; sculpture cancellate;
♦ teleoconch of about 4.5 convex whorls with 3 granular spiral cords on penultimate whorl; rounded periphery; P2 and P3 appearing first, PI a bit later; on last whorl, P2 and P3 widely spaced, SI and S2 appearing and S4 peripheral,;
♦ aperture with denticles all around outer lip;
♦ columella with one small basal tooth with U-notch below;
♦ convex base with 4 granular spiral cords; distance between cords 1 x to 1.5x the size of cords;
♦ no umbilicus;
♦ whitish.
Herbert (2012) pointed out that this species, described from "Coral seas, China", is poorly known and that the two widely spaced main spiral cords are distinctive. Using the little available information about this species, it seems difficult to distinct the numerous samples from the lectotype of the USNM: at most can be said that the spiral cords of the whorls seem thinner for some samples than those of the Coral sea type. Considering this impossibility to differentiate the specimens only on a conchological base, Herpetopoma verruca seems to be the oldest available name to gather all these samples from Solomon Islands to New Caledonia and even to Tonga Islands. In this last area, the only two sample collected are a little stockier; strangely, the columellar tooth is only fully visible from a three-quarters view.
