Tyrrhenocythere sp. 1

Description. The carapace of this species strongly resembles the rectangular to oblong-oval shape observed in T. pontica . The valve appears slightly more compressed and devoid the crest but otherwise bears most of the previously described morphological features. The posterior end bears a weakly pronounced shoulder and below continues in a rounded fashion onto the ventral margin that shows concavity in the anterior third. The part above the weakly pronounced shoulder is steeply sloping and passing onto the dorsal margin that is steeply rising until the anterior third where the valve shows its maximum width. From the highest point, the dorsal margin rapidly slopes down to the otherwise rounded anterior. Unlike the small to medium sized cell ornamentation observed on T. pontica , or the finely pitted surface coverage of Tyrrhenocythere ex. gr. bailovi , this species shows larger pits. Dimension: Male: l = 1,07-1,08 mm, h = 0,60 - 0, 62 mm; Female: l = 0,83 – 0, 97 mm, h = 0, 59 - 0, 60 mm.
