Avicularia juruensis “urticans” • 3/4 – 1″

Avicularia juruensis “urticans” (Peruvian pink toe), captive bred, originally from Peru. For many years available as A. urticans, this species typically grows to about 5″.


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

In 2017 Fukashima and Bertani publshed a major revision of the Avicularia genus. [3] Not only was the name Avicularia juruensis restored, but two types (morphotypes) were described. The group found morphotype 2 more widespread (blue squares), distributed from the city of Manaus to the Amazon’s headwaters in Peru and Ecuador (n.b., a blue square also at the Amazon River outlet). [3]

Morphotype 1 is distributed more narrowly along Rio Juruá drainage, from Manaus to Peru (red circles). [3]

Fukashima 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 Fukashima and Bertani is not yet used worldwide in the hobby. Indeed, these spiderlings, captive bred in Germany, came under the label A. urticans. To minimize confusion between old and new, we use the name A. juruensis “urticans.” 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 A. urticans, A. juruensis M1. Fukashima and Bertani, on the other hand, state M2 used to known as A. urticans. There is room for confusion. The hobby is rife with ill-advised and incorrect name changes. Our advice is aways the same. Know your sources, ask about name changes, and refrain from making name changes. Breed sac mates, or at least specimens in the same shipment, and keep good records.

The photos above show variation within the urticans group. Lighting and exposure are the same, no enhancements.
