Material. A single, partial right chela (MAB13510) (holotype).

Locality and stratigraphy. Mitsero; Koronia Member (Pakhna Formation, late Serravallian-early Messinian).

Etymology. Greek plevrotós (πλευρΩΤΌς), meaning ribbed, in allusion to the large grooves on the outer surface.

Description. Inner and outer surfaces are covered with large striae; upper edge is keeled and slightly convex, the lower edge rounded and straight. The striae are perpendicular to the longitudinal axis and are gently sinusoid. The medial striae have a steep edge at the proximal side, and a smooth edge on the distal side of edge groove. This is present, but less pronounced at the lateral side of the chela. The fixed finger is broken off.

Remarks. Dardanus plevrotos sp. nov. closely resembles Ciliopagurus substriatiformis (Lőrenthey in Lőrenthey and Beurlen, 1929) with the major differences found in the sinusoid shape of the striae in the latter, while the former has a rounded lower edge and the striae continue onto the distal side.
