Figure 20 from: Kirichenko N, Huemer P, Deutsch H, Triberti P, Rougerie R, Lopez-Vaamonde C (2015) Integrative taxonomy reveals a new species of Callisto (Lepidoptera, Gracillariidae) in the Alps. ZooKeys 473: 157-176. https://doi.org/10.3897/zookeys.473.8543

Figure 20 - Genitalia measurements (mean values ± standard error) for the two Callisto species studied. The bars marked by an asterisk are significantly different from each other (MWT: Z = 2.36, N = 16, p = 0.02); in others cases, there is no difference between the species.
