Table 2. Barcode gap analysis for some species-rich taxa of European geometrids.

Taxon	Number of species	Number of specimens	Mean intraspecific variation	Mean maximum variation	Mean distance to congenerics	Mean nearest neighbour divergence
[5 subfamilies]	183	1610	0.70%	1.56%	8.8%	4.4%
Idaea	88	710	0.75%	1.64%	9.0%	4.5%
Scopula	33	309	0.57%	1.23%	9.4%	4.1%
Cyclophora	13	151	0.11%	0.50%	4.0%	1.7%

Total number of species and specimens from Europe with barcodes >500bp. Mean intraspecific variation and maximum variation (Kimura two-parameter genetic distances) are calculated for all representatives of the different taxa. The mean (pairwise) distance to congenerics was calculated using the distance summary function in BOLD. Mean nearest neighbour divergence was averaged from the minimum nearest neighbour divergences given for all species in Appendix S1.
