Key to genera and species of Rutelini View in CoL based on known pupae (modified from Bento et al. (2018))
Pupae of Macraspis morio Burmeister, 1844 were measured and figured by Oliveira et al. (2016), those of Pelidnota punctata (Linnaeus, 1758) were figured by Isaac (1907), and those of Rutelisca durangoana Ohaus, 1905 were described by Morón & Deloya (1991) bearing 5 pairs of dioneiform organs. More morphological studies are needed to differentiate the pupae of these species from others.The pupae of Macraspis (step 14 and subsequent steps) included here need more studies to clarify and check some diagnoses.
