Figure 3 from: Basibuyuk H, Budak M, Korkmaz E (2011) A molecular phylogeny of the Cephinae (Hymenoptera, Cephidae) based on mtDNA COI gene: a test of traditional classification. ZooKeys 130: 363-378. https://doi.org/10.3897/zookeys.130.1466

Figure 3 - Likelihood mapping analysis of the sequence alignments of COI gene present in the Cephinae. The regions at the corners of the triangles correspond to the three possible tree topologies for a quartet; the lateral regions to partly resolved trees and the central region to unresolved trees. The numbers indicate the percentage of quartets falling in each region.
