Brasilocypria View in CoL gen. nov.
Type species: Brasilocypria pea View in CoL gen. et spec. nov.
Diagnosis (see also Table 3 View TABLE 3 ). A2 with short seta accompanying five natatory setae absent. Md-palp with β-seta long and stout; length of last segment ca. 3x 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. T2 with d1-seta absent, setae e and h 3 in male short. T3 with d2-seta absent, dp-seta present; h2-seta ca. 2x the length of h1-seta. Proximal Sp-seta on CR long. Hp with lobe ls generally longated; lobe ms elongated or broad, generally shorter than ls. Ovarium posteriorly turned upwards ( Figs 13B, H View FIGURE 13 ).
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 d2-seta on T2 and T3 (these setae present in Physocypria ) and by the ovarium which curves backward and upward (downward and forward in Physocypria ). Brasilocypria gen. nov. differs from Keysercypria by the relatively shorter final segment of the Md-palp (L = 3x W in Brasilocypria 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 long proximal seta on the CR (medium length in Keysercypria ) and especially by the short h3-seta in the male (very long in Keysercypria ). Brasilocypria gen. nov. is further distinguished from Claudecypria gen. nov. by the presence of dp-seta on T3 (absent in Claudecypria gen. nov.) and by the Hp and prehensile palps which follow the body plan of Physocypria (hyper-developed and with swollen shields and segments in Claudecypria gen. nov. — see below). Brasilocypria gen. nov. furthermore, differs from the subterranean genera Kempfcyclocypris and Namiotkocypria by at least the reduced natatory setae on the A 2 in these genera.
Etymology. The genus is named after the largest country in South America, from which all the present material was collected, with the root “ cypria ”.
