From: New transitional fossil snakeflies from China illuminate the early evolution of Raphidioptera
Evolutionary chronogram of Raphidioptera. A, Interfamilial phylogeny of Raphidioptera based on present result; broad lines indicate known geological distributions; black lines are hypothesized ranges; habitus photos of Chrysoraphidia (Priscaenigmatomorpha: Chrysoraphidiidae fam. nov., Juroraphidia gen. nov. (Juroraphidiidae fam. nov.), Mesoraphidia (Raphidiomorpha: Mesoraphidiidae), Inocellia (Raphidiomorpha: Inocelliidae) and Xanthostigma (Raphidiomorpha: Raphidiidae) are shown from top to bottom, with red arrows marked to indicate the relative length of prothorax; B, Plot of change of snakefly species numbers over time; proportional species number = species number in relevant geological period/total number of known extant and extinct snakefly species; species number of each geological period (i.e. Early Jurassic, Middle Jurassic, Late Jurassic, Early Cretaceous, Late Cretaceous, Eocene, Oligocene, Miocene and Holocene) shown at relevant scale.
