FIGURE 10. Neighbour-joining clustering of 26 DNA barcoded Devernodes type specimens performed using the online BOLD tree-building engine and Kimura 2-parameter. Branch length shown is proportional to relative divergence with scale bars indicating 0.02 units. Red dots denote illustrated specimens from each of six clusters; “HT” denotes holotypes; images are to scale. Unless otherwise indicated, all type specimens are stored in CNC.

FIGURE 11. Maximum Likelihood inference phylogram of Devernodes weevils from a three fragment dataset with 3223 aligned positions. Digits at internodes are bootstrap values of 60% and more. Branch length shown is proportional to relative divergence with scale bars indicating 0.2 units.

FIGURE 12. Geographical distribution of recent Lymantini. Northernmost limits in North America follow Anderson (2016); southernmost limits are based on country records (Alonso-Zarazaga & Lyal 1999) and are fuzzy to reflect uncertainty. New country records (Peru, Guyana, Surinam) are based on unpublished records of Ithaura (Robert Anderson, personal communication). Map design: Jessica Hsiung.
