Abstract
AbstractMedeteraFischer von Waldheim is the most speciose genus in the Medeterinae, with a nearly ubiquitous global distribution. Phylogenetic relationships withinMedeteraand betweenMedeteraand four other medeterine genera were investigated using mitochondrial (COI, 16S) and nuclear (18S) markers to test morphological hypotheses. Our results confirm most of Bickel's hypotheses.ThrypticusGerstäcker shows a sister-group relationship withMedetera+DolichophorusLichtwardt. TheMedeteraspecies included here split into two clades. One clade corresponds to theM. diademaL. –velesLoew species groupsensuBickel. The second clade is largely composed of theM. apicalis(Zetterstedt) species groupsensuBickel and theM. aberransWheeler species groupsensuBickel +Dolichophorus. Although most Medeterinae are associated with plants (mainly trees), species in at least two separate lineages demonstrate a secondary return to terrestrial habitats. The implication of this evolutionary phenomenon is briefly discussed.
