FIGURE 4 in The first molecular phylogeny of the weevil subfamily Lixinae (Coleoptera Curculionidae) casts doubts on the monophyly of its tribes

FIGURE 4. Mouthparts of Lixinae and their relatives within the CCCMS clade; ventral view. Labial palpi are enlarged, red arrows point at the proximal seta-bearing (except Sternuchopsis) labial palpomere. Note that the labial palpi of Lepyrus and Liparus are distinctly three-segmented and at least twice longer than the maximal width of the proximal palpomere. Labial palpi of Lixinae and of Sternuchopsis, in contrast, are not longer than the maximal width of the proximal palpomere, while both distal palpomeres are either much shortened, or indistinct.
