Bayesian (BEAST) maximum clade credibility COI tree of the genus Alainites in the West Palearctic: branch ends labelled with GBIF codes in bold indicate newly sequenced specimens; the DTNHM1449-21, TDAAT323-19, and VMCOL019-20–VMCOL021-20 codes are from BOLD; the other codes correspond to sequences obtained from GenBank. Colored vertical boxes indicate species delimitation hypothesis according to the ASAP, mPTP, and GMYC methods. For each MOTU, the corresponding species names (where available) and the country/region of origin is provided, with the newly described species and associated GBIF codes specified in bold. Circles on branches indicate Bayesian posterior probabilities > 0.9. Outgroup branches, labels, and species names are presented in grey.
