Abstract
A new cassid species of the genus Phalium Link, 1807 is described from material trawled in the Sunda Shelf. Phalium pseudobandatum, new species, is superfi cially close to P. bandatum (Perry, 1811) because of similarities in shell colour and markings. However, the new species can be separated from P. bandatum by conchological characteristics. The position of the posterior sinus in the new species is at or extends above the shoulder, accompanied by a low spire with a side profi le that is smooth and not step-like. It also has a less rotund body whorl with a more angular shoulder compared to P. bandatum. A distinct groove on the parietal shield where it adjoins the body whorl is also present on shells of the new species. In addition, the thickened middle part of the outer lip is not seen in similarly sized specimens of P. bandatum. The siphonal canal of the new species is not pigmented, and the crenulations at the anterior edge of the outer lip are more numerous but less distinct than in P. bandatum. We also suggest that P. exaratum (Reeve, 1848) is a distinct Indian Ocean species rather than a geographical subspecies of P. bandatum.
