Figure 1. The log₁₀ of cryptic species reports (CSR) as a function of the log₁₀ number of described species in the respective taxon. Deviations from the regression line represent CSR taxon variation. Dashed lines represent 95% confidence intervals.

Figure 2. Regression of CSR taxon variation on taxon study bias for 19 metazoan taxa. Dashed lines represent 95% confidence intervals.

Figure 3. The log₁₀ of CSR as a function of the log₁₀ number of described species in the respective region. Deviations from the regression line represent CSR region variation. Dashed lines represent 95% confidence intervals.
