FIGURE 4 in Toward a unified taxonomy of Niphargus (Crustacea: Amphipoda): a review of morphological variability

FIGURE 4. Shape and setal patterns of the telson. A: N. rostratus, arrow indicates the shifted position of lateral plumose setae (after Sket 1971); B: N. brachytelson (after S. Karaman 1952); C: N. valvasori (after S. Karaman 1952); D: N. multipennatus, note elevated number of plumose setae (after Sket 1972); E: N. macedonicus (after S. Karaman 1950); F: N. orcinus (after S. Karaman 1950); G: N. illidzensis (after S. Karaman 1932); H: N. croaticus, note shallow telson cleft (after Jurinac 1888); I: N. sanctinaumi (S. Karaman 1943a); J: N. podgoricensis (after S. Karaman 1950); K: N. illidzensis, w—telson width, l—telson length, cl—telson cleft length, sl—length of the longest spine, AS—apical telson spines, LS—lateral telson spines, MS—mesial telson spines (along telson cleft), DS—dorsal telson spines (adapted from S. Karaman 1932).
