Historical biogeography of Alena Navás, 1916 (Neuroptera: Raphidiidae). A: chronogram showing intergeneric relationships within Alena Navás, 1916 (based on the topology results recovered in the equal and implied weight analysis using constant k values of 3–10), reconstructed ancestral areas mapped for each node. B: biogeographic provinces of Mexico and southwestern U.S.A., after Escalante et al. (2013, 2021) and Morrone (2019).
