It has been observed in the Machay Reserve on Cerro Mayordomo, at 2970 meters above sea level.

[1][2] The adult female frog measures about 72 mm in snout-vent length.

Scientists note that the frog is toxic: Handling specimens with bare skin caused tingling, itching, and pain that lasted for hours.

[3][4] Scientists observed this frog sitting in bromeliad plants 60–90 cm above the forest floor.

[2] The species was named in honour of Family Guy creator and television performer Seth MacFarlane.
