Shell moderately large, up to 59.4 mm; dextral or sinistral; high-conical.Thick, little or not transparent,smooth and polished.
Shell greenish-yellow or straw colour; later whorls omated with irregular spaced radial brown and light brown lines,reaching the suture. Apex yellow, smooth and shining; earlier whorls yellow, paler below;white subsutural zone on later whorls. Whorls slightly convex, increasing regularly in size Fine radial striae and weak spiral striae.
Aperture oblique, ovate, yellowish-white within. Parietal wall brown or purplish-brown, overlaid by darker marginal callus. Peristome white, thickened, expanded and little reflected. Columella vertical, dull brownish-purple externally around lower half of last whorl Umbilicus closed or nearly closed.

Other large and high-conical Amphidromus that resemble Amphidromus puspae, are the yellow A.javanicus Sowcrby, 1841 from West Java, and A. inversus inversus Muller. 1774 from Malava. Sumatra, some satellite islands are north of West Java. They are different in having a dull surface, and radial streaks or bars compared to the radial lines in Amphidromus puspae. A. javanicus has a white parietal callus and coarser radial striae. A.inversus inversus has a brown edged outer lip, a darker colour below the periphery, a light zone around the umbilicus and a dark brown parietal wall overlaid by a white marginal callus.
With their purplish-black parietal wall A. janus Pfeiffer. 1854. from Mergui Islands (Burma) and A.atricallosus atricallosus Gould. 1843 from Burma, Thailand. Malaya (LAIDLAW & SOLEM. 1961) are rather close to A. puspae. Amphidromus janus is smaller, the colour pattern is spirally oriented, while A. atricallosus atricallosus has more convex whorls and usually has one or more dark varices.
