Phylogenetic Analysis of the North American Beetle Genus Trichiotinus (Coleoptera: Scarabaeidae: Trichiinae)

Figure 2

Topology of Trichiotinus found using both parsimony and Bayesian analyses and with all three data sets combined (CO1, 28S, and morphology) as well as a parsimony analysis using just the CO1 data. This is considered the best supported topology for the genus. Clade support values from the Bayesian analysis (above) and bootstrap/jackknife values (below) from the parsimony analysis are shown adjacent to each node, respectively. The two major clades discussed are labeled as 1 and 2 and the two included T. affinis sampled from Kentucky and Quebec are indicated.
