Abstract The skeletal parts of the metendosternite and of the anteromedian part of the abdominal venter are studied in 39 species of Chrysomelinae (representing tribes Timarchini and Chrysomelini, and 10 of the 12 subtribes of Chrysomelini) and 4 species from Galerucinae, Cri- ocerinae, and Cassidinae. The morphology of these body parts in Chrysomelinae is compared with other cucujiform beetles based on the literature, with a focus on a tenebrionid. The morphology of the metendosternite evidently includes much homoplasy across Cucujiformia including Chrysomelidae, whereby conclusions on the polarity of characters are very limited. The (fairly poor) phylogenetic evidence from the chrysomeline metendosternite is discussed including reflection of the current classification, of the only large-scale molecular-based phylogenetic study of Chrysomelinae, and of phylogenetic evidence from glands and their secretions. Chrysomelinae consistently have a very short metendosternal stalk, the anterior tendon originates far laterally from the furcal arm, and the anterior lamina is limited to the fur- cal arm or entirely absent (i.e.
