Tree visualization of the novel characters of the pseudocephalon. Anastrepha phylogeny and relationships of species within the mucronota group (clades and branches in orange) were taken from Mengual et al. (2017). The larval characters are indicated for the six selected traits: (1) Preoral organ and preoral lobe; (2) Position of the preoral organ; (3) Posterior margin of the oral ridges; (4) Accessory plates; (5) Posterior margin of the accessory plates; (6) Vertical comb-like processes.
