Splendrillia sarda is a species of sea snail, a marine gastropod mollusk in the family Drilliidae.
The small, brownish-orange to yellowish, claviform shell has a length of 9.2 mm, its diameter 3.7 mm. The smooth protoconch is small (height about 0.8 mm) and consists of 1½ whorl, the teleoconch contains 5½ whorls.. The axial ribs are strong (with 9-11 ribs on the penultimate whorl). The body whorl has an inverted cone shape and its dorsum is not prominently humped and with a low and distinct varix. The short siphonal canal is relatively wide and twisted slightly to the right. The aperture is narrowly pear-shaped. The outer lip is somewhat flattened in the middle. The base of the columella is strongly curved to the left.[1]
This marine species occurs off the upper continental slope of Transkei, South Africa.
