Figure 5: Ultrametric gene tree including all COI
haplotypes used for species delimitation with the GMYC model. Red
branch splits show the intra-specific divergence within clusters
that correspond to different OTUs (Operational Taxonomic Units) or
putative species. Black lines and Linnean species names on the right
indicate the species identity according to morphological determination.
Red lines show monophyletic Iberian clades within recognized Linnean
species. Blue lines indicate Iberian clusters classified as different
putative species by GMYC. Green line (E. quercaria) shows monophyletic
Italian clade within recognized Linnean species. Purple line (W.
uncinula) indicates Italian cluster classified as different putative
species by GMYC. The letters besides the scientific name in the taxon
labels indicate the country/ies in which each haplotype was recorded
(AUT-Austria; CRO-Croatia; CZR-Czech Republic; FIN-Finland; FRA-France;
GER-Germany; GRE-Greece; ITA-Italy; NED-Netherlands MAC-Macedonia
ROM-Romania; SLO-Slovenia; SPN-Spain and UK-United Kingdom).
