Haustellum

Ponder & Vokes (1988) and Vokes (1990) included American and Indo-Pacific species in Haustellum, which differs from Murex sensu stricto by lacking a labral spine.

Petuch (1994) introduced Vokesimurex for the American long-canalled Haustellum sensu Vokes (1990), such as Murex messorius Sowerby, 1841.

Houart (1999) transferred 14 Indo-Pacific species and three subspecies of Haustellum in the genus Vokesimurex.

Members of Haustellum generally differ from those of Vokesimurex in having a globose and low-spired shape, a more rounded aperture, a smooth columella, a less deep anal notch, and no cord spine.

It is recorded from the Miocene of Borneo (Beets, 1941), the Pliocene of Java, Indonesia and the Plio-Pleistocene of the Malaysian Archipelago.
