Abstract
- 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. [ABSTRACT FROM AUTHOR]
