The Chaco golden knee is a large tarantula, being able to reach between 7 and 8 inches in legspan (17.8-20.3 cm).

It exhibits a multitude of colors, with bright yellowish leg stripes, dark black "femurs", and pink hairs all over its body.

The Chaco golden knee is a very calm and docile tarantula, which, along with its striking appearance and large size, makes it an attractive pet.

It frequently sits in plain view in captivity, and likes to shove substrate around, especially at young ages.

When it was first imported into the pet trade, it was thought to be a variant of the Pink zebra beauty, but it is significantly larger and can be distinguished by the size difference and coloring.
