Figure 7 from: Smit J, Reijnen B, Stokvis F (2013) Half of the European fruit fly species barcoded (Diptera, Tephritidae); a feasibility test for molecular identification. ZooKeys 365: 279-305. https://doi.org/10.3897/zookeys.365.5819

Figure 7 - Relative ID errors at 30 arbitrary threshold values for a. the entire dataset (n = 555), b. the stripped dataset, e.g. excluding singletons and Urophora (n = 414) and c. the stripped dataset excluding the problematic Terellia groups. Linear regression was used to infer the ad hoc threshold for the 95th percentile of the correctly identified queries and the relative ID error does not exceed 5%. In (a) and (b) this value is below 0.00, only in (c) this value is positive: 0.051 (R-square 0.91).
