Figure 1.

(a) Bayesian phylogeny based on 1999 bp combined of the mitochondrial cytochrome b and the nuclear ribosomal S7 gene. Branch lengths are proportional to number of character changes. Bayesian support is indicated if >0.75. Representative photos and examples of EOD wave types for the three species examined are shown to the right. (b) EOD divergence among species demonstrated in a PCA using 10 EOD characteristics (§2). Different symbols refer to different species (triangle, C. rhynchophorus; circle, C. compressirostris; plus, C. tamandua).
