FIGURE 5 in Toward a unified taxonomy of Niphargus (Crustacea: Amphipoda): a review of morphological variability

FIGURE 5. Variable proportions of parts of antenna I (A–F), antenna II (L–N) and various degree of development of additional structures. A: N. macedonicus, l1–l3 indicate the lines along which we measured the lengths of antenna I peduncle (adapted from S. Karaman 1950); B: N. orcinus (after S. Karaman 1950); C: N. grandii (after Sket 1972); D: N. krameri (after G. Karaman 1984b); E: N. pectinicauda (after Sket 1971); F N. rostratus (after Sket 1971); G: accessory flagellum of N. jovanovici (S. Karaman 1943a); H: accessory flagellum of N. rostratus (after Sket 1971); I: number of aesthetascs in N. macedonicus (S. Karaman 1943a); J: number of aesthetascs in N. smederevanus (after S. Karaman 1950); K: visor on the peduncle article I of antenna I in N. pupetta (after Sket 1971); L: N. dalmatinus l4–l6 indicate the lines along which we measured lengths of antenna II (original drawing); M: N. grandii (after Sket 1972); N: N. croaticus (after Jurinac 1888).
