FIGURE 1 in Toward a unified taxonomy of Niphargus (Crustacea: Amphipoda): a review of morphological variability

FIGURE 1. Body types and variability of body sizes. A: Niphargus pupetta, (4 mm, after Sket 1971); B: N. jovanovici (10 mm, after S. Karaman 1943a); C: N. skopljensis, (7.5 mm, after S. Karaman 1943a); D: N. balcanicus (30 mm, after S. Karaman 1932); E: N. macedonicus (19 mm, after S. Karaman 1943a); F: N. sanctinaumi (22 mm, after S. Karaman 1943a); G: differences in size between N. orcinus and N. transitivus (25 and 2.2 mm, respectively, adapted from Sket 1999). Note the variability in general aspects of proportions of some body parts such as lengths of antennae, pereopods, uropods and size of gnathopods. The polygon on N. macedonicus indicates the line along which we measured the body length.
