Biconic-fusiform, b/l 0.44-0.50, a/l 0.46-0.48; aperture linear, siphonal canal rounded truncate, not indented; whorls with strong, slopingly tabulate shoulder, median on early whorls, at subsutural third on later ones. Outer lip convex in side view, with slight trace of stromboid notch, anal sinus shallow, broadly U-shaped; edge of lip sharp, preceded by a high, compressed varix; interior of outer lip with 9-12 short transverse pleats, those below anal sinus denticle-like; inner lip with 10-12 transverse denticles, weak in lower parietal area, crossing lip to form weak nodules on interior. Sculptured by strong axial ribs, not aligned across whorls, crenulating suture on later whorls, crossed by narrow, high spiral ridges. Axial ribs extending from suture to base, arcuate, slightly procurved below suture, in t/s high, compressed, somewhat angular, much narrower than the flattened intervals; 12-13 on first teleoconch whorl, 9-10 ribs on penultimate whorl. Spiral sculpture fine and even on first teleoconch whorl, later whorls with widely spaced main ridges, their intervals with fine, close spiral threads, cancellated by collabral threads; main ridges rounded but with sharply incised edges, 5-6 on penultimate whorl, subsu¬tural concavity with fine, dense threads. Dimensions: 4.6 * 2.3 mm, aperture 2.2 mm; 3.9 * 1.7 mm, aperture 1.8 mm.
Dull white, dorsal side of last whorl with irregular brown to pale orange-brown blotch, back of outer lip with rust-coloured stain.
Protoconch conical, with 2 strongly convex whorls, first one depressed, smooth, breadth 0.33-0.36 mm.

Eucithara makadiensis superficially resembles some members of the genus Heterocithara Hedley, 1922, in shape, but differs in possessing a row of denticles on the inner lip. Eucithara (s.l.) vittata (Hinds, 1843) lacks a strongly angular shoulder and is zoned with brown. There is some slight resemblance to Eucithara capillata (Hervier, 1897), but E. makadiensis has a much stronger shoulder and coarser, more widely spaced spiral ridges.
