The Yungas Tyrannulet, scientifically known as *Phyllomyias weedeni*, is a diminutive and often inconspicuous member of the Tyrannidae family, measuring approximately 11.5-12.5 cm in length and weighing a mere 8-10 grams.

This species primarily inhabits humid montane cloud forests and subtropical evergreen forests, typically found at elevations ranging from 1000 to 2500 meters.
