FIGURE 2 in Systematics of the weevil genus Mecinus Germar, 1821 (Coleoptera: Curculionidae). II. Phylogenetic analysis based on adult morphological characters and host plant information

FIGURE 2. Phylogenetic hypothesis for the species of Mecinus based on morphological characters only. The diagram is a majority (50%) rule consensus tree with unambiguous character state optimizations, derived from parsimony analysis of the morphological equal-weights matrix (31 characters). Character (above) and state (below) distributions are mapped under unambiguous transformation. Black squares indicate unique transformed characters whereas white circles represent homoplastic characters.

FIGURE 3. Phylogenetic hypothesis for the species of Mecinus based on morphological and ecological characters. The diagram is a majority (50%) rule consensus tree with unambiguous character state optimizations. 34 characters are weighted using an iterative a posteriori weighting procedure. Character (above) and state (below) distributions are mapped under unambiguous transformation. Black squares indicate unique transformed characters whereas white circles represent homoplastic characters.
