FIGURE 3. Pleon and urosoma. A: pleonites II–III of N. dalmatinus, dorsoventral lines illustrate the approximately perpendicular and sharply inclined distoposterior angle of epimeral plates (original drawing). Variability in shape and number of dorsoposterior setae along pleonites I–III (dorsal view, the position of setae indicated by arrow): B: N. lunaris (after G. Karaman 1985); C: N. salonitanus (S. Karaman 1950); D: N. bilecanus (after S. Karaman 1953). Variable shape of epimeral plates: E: N. balcanicus, arrows indicate setae along posterior margin and setae along subventral margin (after S. Karaman 1932); F: N. illidzensis (after S. Karaman 1932); G: N. valachicus (after S. Karaman 1950); H: N. pectinicauda (after Sket 1971); I: N. skopljensis (S. Karaman 1943a); J: N. orcinus (after S. Karaman 1950); K: N. jurinaci (after S. Karaman 1950); L: N. dalmatinus (after S. Karaman 1950); M: N. pannonicus (after S. Karaman 1950). Setal patterns on urosomites I–III: N: N. dalmatinus (urosomites I–II, original drawing); O: setae on humps in N. balcanicus (after S. Karaman 1932); P: setae on urosomite III in N. podgoricensis (rarely present otherwise) (arrow, after G. Karaman 1984a); spine-like seta at the base of uropods I (arrow) may be multiplied in some species.
