Fig. 1. Phylogenetic relationships of Thyropygus species based on maximum likelihood analysis (ML) and Bayesian Inference (BI) of 1147 bp of concatenated gene fragments of COI (660 bp) and 16S rRNA (487 bp). Numbers at nodes indicate branch support based on bootstrapping (ML) / posterior probability (BI). Scale bar = 0.06 substitutions/site. # indicates branches which received <50% ML bootstrap support, - indicates non-supported branches by posterior probability. Clade memberships and designations are shown as vertical bars; 1A1 = T. allevatus, 1A2 = cuisinieri subgroup, 1A3 = opinatus subgroup and 1A4 = induratus subgroup. The coloured area marks the T. opinatus subgroup. Abbreviations after species names refer to locality names as shown in Table 1.
