FIGURE 1 in Molecular phylogeny of the weevil genus Dichromacalles Stüben (Curculionidae: Cryptorhynchinae) and description of a new species
FIGURE 1. Phylogenetic hypothesis for the western Palaeartic genera of the subfamily Cryptorhynchinae Schoenherr, 1825, based on type species (gray shaded) and others. Bayesian 50% majority rule consensus tree built from mitochondrial COI+16S and nuclear 28S gene sequences. Numbers next to nodes indicate posterior probabilities in percent. Name of each species is followed by internal extraction number in brackets (in three cases complemented sequences derived from two individuals with different extraction numbers). See Table 1 for collecting data. Photos on the right side show some of the species listed in the tree.
FIGURE 37 in Molecular phylogeny of the weevil genus Dichromacalles Stüben (Curculionidae: Cryptorhynchinae) and description of a new species
FIGURE 37. Comparison of Bayesian 50% majority rule consensus trees built for Dichromacalles from COI dataset (left), COI+16S dataset (middle) and COI+16S+28S dataset (right; same as in Fig. 2). In all trees Dichromacalles lentisci is grouped within an own clade, suggesting it to be a good species, distinct from others. Using only COI data D. lentisci is obtained as the sister taxon of the clade D. albopictus + D. tuberculatus + D. querilhaci. Adding the 16S dataset leads to D. lentisci being placed in a trichotomy with D. albopictus + D. tuberculatus + D. querilhaci and D. rolletii + D. boroveci + D. creticus. By using three genes (COI+16S+28S dataset) we receive a tree where D. lentisci is positioned as the sister species to D. rolletii + D. boroveci + D. creticus. The Bayesian posterior probability values increased in the parent clade of D. lentisci from 91.4% (COI dataset, 658 nt) to 93.1% (COI+16S+28S dataset, 1528 nt).
FIGURE 2 in Molecular phylogeny of the weevil genus Dichromacalles Stüben (Curculionidae: Cryptorhynchinae) and description of a new species
FIGURE 2. Phylogenetic hypothesis for the Palaeartic species of the genus Dichromacalles Stüben, 1998. The clade of the new species D. algecirasensis is gray shaded. Bayesian 50% majority rule consensus tree built from mitochondrial COI+16S and nuclear 28S gene sequences. Numbers next to nodes indicate posterior probabilities in percent, country abbreviation and internal extraction numbers are given in brackets (CI: Canary Islands, E: Continental Spain, F: France, GR: Greece, I: Italy, Mo: Morocco, P: Portugal). See Table 2 for collecting data. Fotos on the right side show most of the species listed in the tree together with their host plants.
