The syringeal morphology of several species t is very different from that of other species of Ochthoeca (Lanyon 1986), and it also are deeply divergent genetically from other species of Ochthoeca (Ohlson et al. 2008, Tello et al. 2009, Harvey et al. 2020). Therefore we transfer these species to the genus Silvicultrix Lanyon 1986. Change the scientific name of Yellow-bellied Chat-Tyrant from Ochthoeca diadema to Silvicultrix diadema.
