Eucyclotoma albomacula is a species of sea snail, a marine gastropod mollusk in the family Raphitomidae.

[1] It was first described by E. Alison Kay in 1979 and is distinguished by a single spiral keel on each whorl with axial white stripes; the species name (albomacula) is derived from the Latin albo (white) and macula (speck or spot).

The shell is described as glossy, chestnut brown with three axial streaks of white colour.

It has a widely oval aperture about one-fifth the total length of the shell, a thin outer lip with protrusions of the spiral keels.

[2] Eucyclotoma albomacula are rare, found at mesophotic depths between 59 m to 195 m (194 - 640 ft).
