Pseudoclamoris burgessi

Pseudoclamoris burgessi comes from Brazil's Atlantic Forest — one of the most threatened and biologically dense ecosystems on the continent — and carries something of that forest's intensity with it. The body is dark, almost charcoal, yet catches the light with a greenish metallic sheen that shifts with angle and illumination. The build is slender and lightly framed, every proportion oriented toward vertical space and the rapid negotiation of bark and branch. This is unmistakably an animal shaped by the canopy.

What defines Pseudoclamoris burgessi in the hand — or rather, what you quickly learn not to underestimate — is its speed. Like Psalmopoeus and Tapinauchenius, this species carries no urticating setae; its defence is velocity and unpredictability rather than passive armament. It is alert, confident, and fast enough to make an enclosure feel considerably smaller than its dimensions suggest. Given settled conditions and adequate prey, Pseudoclamoris burgessi grows quickly and feeds with consistent enthusiasm, spending much of its visible time repositioning within its silken tube retreat or scanning from its anchor point with the stillness of something actively waiting.

The enclosure should be oriented vertically, with height prioritised over footprint, and furnished with cork bark or a cork tube placed high enough to serve as a genuine retreat rather than floor decoration. Regular misting keeps humidity appropriately elevated without waterlogging the substrate, and a water dish at the base remains available for the descents the spider makes on its own schedule. Room temperatures in the low-to-mid twenties Celsius are sufficient; there is no need to push the enclosure into the thirties. The one condition genuinely worth avoiding is stagnant air at elevated humidity, so cross-ventilation should be built into the enclosure from the outset.

Pseudoclamoris burgessi suits the keeper who has already built a relationship with arboreal Theraphosidae and wants to extend that collection toward something with a sharper profile and a narrower ecological story behind it. Years in, what tends to hold the attention is not only the metallic sheen catching the light across the enclosure, but the awareness that this animal belongs to a lineage tied to a forest now reduced to less than twelve percent of its original range — a weight that purely cosmetic appeal rarely sustains on its own.
