A probably young shell from Station 10 (Shark Bay) is characterized by an embryonal shell composed of almost 4 brown whorls. The teleoconch whorls are without colour and start after the larval shell abruptly. The teleoconch is composed of 5 clearly convex whorls with an angulated profile. The whorls have 4 strong spiral cords and some broad, wave-like, axial ribs. The columella is short, the siphonal canal broad. Height 2.4 mm, diameter 0.65 mm.

Diagnosis
Shell dextrally coiled. Holotype 2.4 mm high, teleoconch composed of five whorls; however, this specimen is likely a subadult. Whorls have eight orthocline axial ribs and three main flat spiral cords; the last two whorls have a sub- and supra-sutural cord. The whorl profile is angulated due to the prominence of the cord in the middle of the whorl. Protoconch multispiral, composed of at least four whorls (but holotype apex is damaged), with zigzag threads on the first and second whorl, followed by axial riblets. Protoconch brown, teleoconch white with occasional tiny faint brown patches on spiral cords between axial ribs.

Remarks
Although the examined type specimen is likely a subadult, the specimen identified as Metaxia fuscoapicata illustrated by Marshall (1983, figure 9 A-C) may not actually be this species: the holotype has much more convex teleoconch whorls (although juvenile), a lower number of axial ribs, a less angulated protoconch periphery and the zig-zag threads still clearly visible on the second protoconch whorl. More adult and complete specimens from the type locality would be needed to better define this taxon and discriminate it from closely related ones.
