Support for and against previously proposed placements of Horologion. Grey: clade present in maximum likelihood tree, SBS less than 90%, UFBoot less than 95% and/or SH-aLRT less than 80. Red: clade absent in maximum likelihood tree, most-supported contradictory clade with SBS 90% or greater, UFBoot 95% or greater and SH-aLRT 80 or greater. Pink: clade absent in maximum likelihood tree, most-supported contradictory clade with SBS less than 50%, UFBoot less than 95% and/or SH-aLRT less than 80. There were not sufficient sequences available for COI and Topo from our sampled Psydrini.
