DESCRIPTION Shell small, conical, sutures moderately impressed. Protoconch conical of 4.5 smooth convex whorls, color brownish, transparent. Teleoconch of 5.2 whorls with reticulate sculpture of 3 equal spiral cords crossed by weaker axial ribs, 18 on last whorl; beads at each intersection. A fourth beaded cord is emerging at the base of the last whorl from the insertion of the outer lip; border between columella and base highlighted by a very weak cord. Columella short and broad, obliquely truncated, with a surface crossed by thin crisp threads, columellar callus bordering a circular aperture; anal sulcus and siphonal canal well defined. Background color brownish, semitransparent; on the last whorls the area between 1st and 2nd spiral cord becomes colorless.
COMPARISON Cerithiopsis recourti n. sp. is compared with Cerithiopsis susieae Rolán & Krisberg, 2014 from Florida (USA), having a similar size and shape but a different color and a smaller protoconch. The smooth protoconch makes it easy to separate it from Cerithiopsis parvada Rolán, Espinosa & Fernández- Garcés, 2007.
