Guraleus janjukiensis is an extinct species of sea snail, a marine gastropod mollusc, in the family Mangeliidae.[1] Fossils of the species date to early Miocene strata of the Port Phillip Basin of Victoria, Australia.
In the original description, Powell described the species as follows:
Ovate-fusiform; whorls strongly convex, not shouldered. Sculptured with heavy rounded axials, 12 per whorl; extending from upper suture completely over base. The sinus area, extending a little more than one third down from the upper suture on the spire-whorls, is delicately sculptured with about 10 very faint threads crossed by equally fine axial hair threads following the shallow concavity of the sinus. Below the sinus area to the lower suture there are 10 narrow crisp threads, and about 30 on the body-whorl. Protoconch polygyrate, conic, of 31⁄2 smooth whorls with minute exserted tip, followed by a half whorl of fine arcuate brephic axials.[2]
The holotype of the species measures 5.75 mm (0.226 in) in length and has a diameter of 2.7 mm (0.11 in).[2]
