A536878FFFD1FFD0FF7E6B82B656FAC4.taxon	diagnosis	Diagnosis: Based on a fossil carapace with characteristics of the family Nannastacidae Bate, 1866, which differs by tubercles, spines and continuously strong serration on anterolateral, lateral, and posterolateral margins of carapace from the other genera of the family.	en	Artüz, M.

A536878FFFD1FFD0FF7E6B82B656FAC4.taxon	description	Description. The material studied consists of twenty-one specimens collected in a period of two years from five localities (Figure 1) in the Upper Pleistocene sediments in the Sea of Marmara. Most of the specimens represent parts of the carapace, except for one nearly complete carapace. In all specimens no ventral structures are present nor are there any indications of the pleon and pleopods. This is not surprising when one considers that generally modern cumaceans have abdomens that are less calcified than the cephalothorax. Carapace with pronounced anterolateral processes, with numerous blunt or acute tubercles and spines. Anterolateral, lateral, and posterolateral margins of carapace are strongly serrated.	en	Artüz, M.
