Nesotriccus
Bird genus - Phylogenetic analysis reveals that Cocos Flycatcher (Nesotriccus) is embedded in the Mouse-colored Tyrannulet radiation (Phaeomyias). Since Nesotriccus has priority over Phaeomyias, the former genus prevails for the merged genus (Zucker et al. 2016). Note that Phaeomyias is feminine but Nesotriccus is masculine. Species-group epithets are modified accordingly.
