Description (holotype): Shell of small size (3.17 x 0.94 mm), cylindrical, slightly inflated, suture deep, colour brown. Protoconch (0.37 x 0.25 mm) of 3 convex whorls, apex rounded; 1 apical whorl ornated with numerous thin cords, next two whorls with sculpture of 20-21 thin prosocline riblets crossed by very thin and oblique spiral cords. Transition to teleoconch marked by a sinusigera lip. Teleoconch of 8,5 whorls, reticular sculpture of three spiral cords of equal size, crossed by weaker axial ribs, about 20-22 on last whorl, with beads at each intersections. The base is composed of one strong cord on the upper part and 2-3 thin cords on the lower part . Columella short, obliquely truncate; ridge bordering an oval aperture with siphonal canal and anal sulcus well defined.

For its protoconch features, Cerithiopsis annaleabeardae sp. nov. is compared with Cerithiopsis capixaba Figueira & Pimenta, 2008 from Brazil and Cerithiopsis tarruellasi Penas & Rolan, 2006 from the Mediterranean Sea.

* C. annaleabeardae differs from C. capixaba by the teleoconch shape, with C. capixaba having a pupoid shape and C. annaleabeardae a cylindrical shape. The sculpture differs in the number of spiral cords, with C. annaleabeardae having three spiral cords of equal size and C. capixaba three spiral cords on the last whorl, with the first being bigger in size than the other two cords. The base is quite different, too: C. capixaba has a very strong columella with three big cords and numerous thin cords, while C. annaleabeardae has a short siphonal canal with only one soft cord in the columella.

* C. annaleabeardae differst from C. tarruellasi by the number of protoconch whorls: C. tarruellasi has a protoconch composed of four whorls and C. annaleabeardae a protoconch composed of three whorls. The protoconch sculptures are very similar, although C. tarruellasi miss¬es the thin spiral cords on the first protoconch whorl. The shapes are slightly different with C. annaleabeardae having much more convex protoconch whorls compared to the ones of C. tarruellasi. The teleoconch differs also in spiral sculpture: C. annaleabeardae has three spiral cords of equal size, while C. tannellasi has three spiral cords with the first one smaller in size than the other two. C. tarruellasi also lacks basal cords, while C. Annaleabeardae possesses 1 strong basal cord and 2-3 thin cords in the lower part.
