| phylogenetic relationships and systematics of a subclade of mesoamerican <br />emerald hummingbirds (aves: trochilidae: trochilini). | phylogenetic relationships among major hummingbird clades are relatively well resolved, yet due to the lack of morphological synapomorphies and relative phenotypic homogeneity, the systematics of several hummingbird groups remain unresolved. here, we present the results of a multilocus study of a clade of emerald hummingbirds composed of cynanthus, chlorostilbon, riccordia and phaeoptila (sensu stiles et al. 2017). we include taxa not analyzed in previous studies (c. lawrencei, c. auriceps and c ... | 2020 | 32230070 |
