Fig. 24 in Widespread polytypic species or complexes of local species? Revising bumblebees of the subgenus Melanobombus world-wide (Hymenoptera, Apidae, Bombus)

Fig. 24. (Most likely ancestral ranges for lineages of the subgenus Melanobombus von Dalla Torre, 1880. reconstructed with DIVALIKE+J (BioGeoBEARS) using the short-distance dispersal (no jumps) model in Fig. 23, the estimate of species phylogeny in Fig. 22, and with B. nobilis representing the outgroup (not shown). Letters represent the area units defined in Table 5 and in Fig. 23: letter combinations in grey below terminals show species' current distributions; letter combinations above the nodes show the most likely reconstructions for ancestral distributions (with four selected dispersal events numbered), with the probabilities of these solutions for these ancestors shown below the nodes. Species groups discussed in the text are labelled in circles: rp = rufipes-group; fs = festivus-group; rf = rufofasciatus- group; tg = tanguticus-group; la = lapidarius-group; si = sichelii-group; and ke = keriensis-group. Inset map shows sequenced samples for the species groups (blue = the rufipes-group and festivus-group; green = the rufofasciatus-group; yellow = the tanguticus-group and lapidarius-group; orange = the sichelii-group; and red = the keriensis-group) with arrows showing the four numbered dispersal events.
