Phylogenetic relationships of 25 genera of Holarctic Teleiodini (Gelechiidae) are postulated based on morphology and molecular characters, including CO‐I, CO‐II, and 28S genes. The phylogenetic analysis of the morphology matrix yielded four equal most‐parsimonious trees (length 330 steps, CI = 0.36, RI = 0.55) and a strict consensus tree (length 335 steps, CI = 0.36, RI = 0.54) with one polytomy and one trichotomy. The phylogenetic analysis of the combined morphology and CO‐I + CO‐II + 28S matrices yielded two equally most‐parsimonious trees (length 1184 steps, CI = 0.50, RI = 0.42) and a strict consensus tree (length 1187 steps, CI = 0.50, RI = 0.42) that reinforced results from the morphological analysis and resolved the one polytomy present in the morphology consensus tree. Teleiodini are defined as a monophyletic clade with a Bremer support value greater than 5 in the consensus tree based on morphological and molecular data. Twenty‐three clades of genera are defined with Bremer support values provided. An analysis of larval host‐plant preferences based on the consensus tree for combined data indicates derivation of feeding on woody hosts from genera feeding on herbaceous hosts and a single origin of feeding on coniferous hosts. An area cladogram indicates five independent origins of Nearctic genera from Holarctic ancestors and one origin from a Palearctic genus.
