Avicularia juruensis “Peru purple” • 7/8 – 1 1/8″


Avicularia juruensis “Peru purple” (Peruvian purple pink toe), captive bred, originally from Peru. For many years available as A. sp. “Peru purple,” this species matures at 4-5″. Recommended for advanced beginners and above.

Mello-Leitão described Avicularia juruensis in 1923, recording the collection site (locality) as “Rio Juruá.” [1] In 1994 Schmidt (mis)identified apparently the same species from Peru as a new species. He named it Avicularia urticans after its irritating hairs (setae). [2]

In 2017 Fukushima and Bertani published  a major revision of the Avicularia genus. [3] Not only do they restore the name Avicularia juruensis, but they describe two versions (morphotypes) of juruensis. They report morphotype 1 along the Rio Juruá drainage, from Manaus to Peru (red circles). [3]

They report morphotype 2 as more widespread (blue squares), distributed from the city of Manaus to the Amazon’s headwaters in Peru, Ecuador and southern Colombia (n.b., a blue square also at the Amazon River outlet). [3]

Fukushima and Bertani describe the outward appearance of A. juruensis morphotype 2:

“Both sexes have very grizzled setae on palps and legs, and carapace, legs and palps with dark short body setae with intense purple sheen, and yellowish leg rings.”

The nomenclature of Fukushima and Bertani is not yet used worldwide in the hobby. Indeed, these spiderlings, captive bred in Germany, came under the label A. sp. “Peru purple.” To minimize confusion between old and new, we use the name A. juruensis “Peru purple.” We await overseas arachnological clarification as to whether these are m1 or m2 (or other).*

*Many in the US hobby call what we knew as Avicularia sp. “Peru purple,” A. juruensis m2, and what we knew as Avicularia urticans, A. juruensis m1. Fukushima and Bertani, on the other hand, state m2 used to be known as A. urticans. Confused?

We suggest acknowledging the revision with the name A. juruensis, but using the modifiers “urticans” and “Peru purple” until we can agree on what m1 and m2 mean.

Thanks to Chase (CEC) of Arachnoboards for help with A. juruensis as discussed in reference 3.
