Figure 9 in Morphological phylogenetics provide new insights into the classification and evolution of fossil soldier beetles from Mid-Cretaceous Burmese amber (Coleoptera: Cantharidae)

Figure 9. Time-dated cladogram of Cantharidae based on molecular phylogenetic frameworks of Zhang et al. (2018) and McKenna et al. (2019), and our cladistic analyses, shows the antiquity and Cretaceous origin of subfamilies. Only the oldest fossils are denoted on the branch: 1, Malthininae from the Mid-Eocene Baltic amber (e.g. Malthinus danieli Kuśka & Kania, 2010); 2, Tytthonyxini from the Early Middle Miocene Dominican amber (e.g. Tytthonyx geiseri Poinar & Fanti, 2016); 3, Archaeomalthodes rosetta Hsiao et al., 2017 from the Mid-Cretaceous Burmese amber; 4, Chauliognathinae The late Eocene Florissant Formation (e.g. Chauliognathus pristinus Scudder, 1876); 5, Molliberus albae Peris & Fanti, 2018 (Cantharinae) from the Early Cretaceous Spanish amber; 6, Mid-Cretaceous Burmite Cantharinae; 7, Silini from the Mid-Eocene Baltic amber (e.g. Silis lombardii Parisi & Fanti, 2019). Geological scale is modified from an updated version of the International Commission on Stratigraphy (ICS) International Chronostratigraphic Chart (Cohen et al., 2013; updated).
