Dardanus cyprioticus sp. nov.

Figure 4A, B

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

Description. Elongated, triangular carapace covered with grooves. The orbital area is broad, rimmed and shallow. The postrostral ridges are indented by a central gastric furrow, which extends posteriorly into a faint central line. Spinose and globose massetic region, posteriorly covered with spizoobank.org/ 7830BD18-EBE7-4380-930F-44A2FEE639CD

Material. A single, near-complete right chela, as part and counterpart in matrix (MAB13511) (holotype); a damaged fragment of a chela (MAB13512) is here considered conspecific.

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

Etymology. The species is named after the island of Cyprus.

Description. Only the lateral surface of the right chela is visible in the matrix. Part of the proximal medial palm is missing. The lower edge of the chela is convex, rounded and covered with striae. The edges of the striae are steep on both sides. The striae on the proximal side are almost the same length and every second ridge is stronger. The striae become shorter near the fixed finger. The upper half of the fixed finger is covered with tubercles, which extend onto the beginning of the palm and cover the upper half of the palm. The moveable finger is completely covered with tubercles.

Remarks. Dardanus cyprioticus sp. nov. closely resembles D. hungaricus (Lőrenthey in Lőrenthey and Beurlen, 1929), but differs in the length of the striae, every other stria being deeper, and in the position of the tubercles on the upper half of the fixed finger.
