Claudecypria gen. nov.

Type species: Claudecypria mesquitai gen. et spec. nov.

Abbreviated diagnosis of Claudecypria gen. nov. (see also Table 3 ). A2 with short seta accompanying natatory setae absent. Md-palp with β-seta long and stout; length of last segment ca. 2x the basal width, apically set with three claws and one seta. Mx1-palp set with five structures (claws and setae). T1 with b-seta short and d-seta long; right prehensile palp with distal protrusion on first segment and second segment hyper-developed. T2 with d1-seta absent, setae e and h 3 in male short. T3 with setae d2 and dp absent; h2-seta ca. 2x length of h1-seta. Proximal seta on CR short. Hp with lobes ls and ms both broad and strongly developed. Ovarium ventrally turned back and upwards.

Differential diagnosis. The new genus can be separated from the genera Cyclocypris, Kempcyclocypris , Cypria , Mecynocypria and Allocypria by the presence of marginal tubercles on the RV; furthermore, from Cypria , Physocypria and Dentocypria by the absence of the short seta accompanying the natatory setae on the A2 and from Physocypria also by the absence of the d2-seta on the T2 and T3 (these setae present in Physocypria ) and by the ovarium, which curves backward and upward (downward and forward in Physocypria ). Claudecypria gen. nov. differs from Keysercypria by the relatively shorter final segment of the Md-palp (L = 2x W in Claudecypria gen. nov., L = 5x W in Keysercypria ;), by the presence of five setae/claws on the second segment of the Mx1-palp (four in Keysercypria ), by the short proximal seta on the CR (medium length in Keysercypria ) and especially by the short h3-seta in the male (very long in Keysercypria ). Claudecypria gen. nov. is further distinguished from most (all?) other genera in the Cyclocypridinae by the absence of the dp-seta on the T3. It is further distinguished from Brasilocypria gen. nov. by the Hp and prehensile palps, which are hyper-developed and with swollen shields and segments (not so in Brasilocypria gen. nov.). Claudecypria gen. nov. furthermore, differs from the subterranean genera Kempfcyclocypris and Namiotkocypria by at least the well-developed natatory setae on the A2 (reduced in these latter genera).

Etymology: The new genus is named after Dr Claude Meisch, in honour of his vast contribution to research on non-marine ostracods, culminated in his important monograph on the non-marine ostracods of Western Europe ( Meisch 2000), and with gratitude for years of friendship with KM.
