FIGURE 1 in Cryptic diversity in the Azorean beetle genus Tarphius Erichson, 1845 (Coleoptera: Zopheridae): An integrative taxonomic approach with description of four new species

FIGURE 1. Bayesian inference tree for Tarphius beetles of the Azores based on 1,383 bp of mitochondrial DNA (COI, tRNA- Leu, COII). Clade credibility values are shown for nodes with a posterior probability ± 0.95. Colored circles with lower case letters (a–g) indicate nodes, encompassing the same species on multiple islands and/or different species, for which most likely ancestral ranges were inferred. Color code for ancestral range matches that of current species distribution (see colored bar underneath island name and island colors in inset map). Inset map also shows island maximum geological age in millions of years (Ma).
