Lucerapex murndaliana is an extinct species of sea snail, a marine gastropod mollusk in the family Turridae, the turrids.

Original description: This neat little species is distinguished by its long siphonal canal and pyramidal spire.

[2]The protoconch is composed of three elongate whorls, the initial portion being slightly inflated, whilst the anterior turns are obtusely carinate.

It contains ten whorls, slightly convex, and has several bold, irregular, spiral threads or ridges, rather rugose where crossed by growth lines, and somewhat granulated in the neighbourhood of the sinus.

[3] Fossils of this extinct species were found in Middle Miocene strata at Muddy Creek, Hamilton, Victoria, Australia.
