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).
