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.

Fig. 5. The best-fit demographic models of (A) Pachyrhynchus sarcitis, (B) P. nobilis and (C) P. semperi inferred from G-PhoCS.Topological assumption based on SNAPP population tree, and the following demographic parameters were estimated according to per-generation mutation rate μ = 2.9 × 10 − 9 and generation time g = 3. The width of the column represents the mean of effective population size (Ne), and the dashed line indicates divergence time (T: Thousand year). Migration rate (mtot) is not demonstrated because all value of mtot is not significant.

Colorful boxes highlight populations from the same island group, and colorful bars represent each island population. Black dots denote the monophyletic lineage that are grouped by an island, and red dots denote the monophyletic lineage that are grouped by more than one island.
