Pamphobeteus sp. "Platyomma"
🔤 Taxonomy
Pamphobeteus sp. “Platyomma” is a provisional hobby label, not a formally accepted species name in World Spider Catalog. Record it exactly as a trade or lineage label, and avoid shortening it to Pamphobeteus platyomma as if that were a stable taxon.
The old name Pamphobeteus platyomma now belongs to Vitalius platyomma, a Brazilian nomen dubium based on inadequate material. That WSC entry is useful because it explains the confusion, but it should not be treated as the identity of animals sold as Pamphobeteus sp. “Platyomma”.
Because this is a provisional label, breeding records should include supplier, locality or line information when known, molt photos, pairing dates, and transfer notes. Do not mix it casually with other purple or pink-bloom Pamphobeteus lines.
English common names and hobby labels:
- Brazilian pink bloom
- pink bloom tarantula
- Pamphobeteus sp. “Platyomma”
📌 Description
Pamphobeteus sp. “Platyomma” is kept as a very large New World terrestrial display tarantula. Mature males can show striking pink, violet, or metallic tones, while females are usually heavier, darker, and more robust.
Adults need planning before purchase. This is a fast-growing, strong-feeding spider that can outgrow small enclosures quickly and can push loose lids, throw urticating hairs, or bolt during water changes.
It is best treated as an advanced display species. The care is not delicate, but the size, speed, uncertain identity, and appetite leave little room for casual handling or improvised housing.
🌍 Distribution
The verified scientific distribution of the exact hobby label is uncertain because “Platyomma” is not an accepted species-level name. Trade material is usually discussed as South American Pamphobeteus, and the genus itself is centered in northwestern and tropical South America.
For husbandry, do not build around a precise country claim unless the seller provides trustworthy locality data. A warm, humid but well-ventilated terrestrial setup with dry walking surfaces and a moist retreat option is safer than trying to copy a vague rainforest label.

⚖️ Legal status
As checked against the current CITES Checklist, CITES Appendices, and EU wildlife-trade references on 2026-06-03, no current CITES listing or specific EU Annex listing was found for Pamphobeteus sp. “Platyomma”. The taxon is not relevant to the Bern Convention because it is not native to Europe.
Local and national rules on collection, export, import, sale, transport, exhibition, breeding, and proof of legal origin may still apply. Keep invoices, breeder details, and import or transfer paperwork where relevant; a non-listed trade status is not proof that every animal was sourced legally.
🤌 Husbandry
Keep Pamphobeteus sp. “Platyomma” singly. It is not a communal tarantula, and adults are large enough that failed cohabitation can become severe quickly.
Start spiderlings in small secure tubs where prey, molt, and hydration can be checked. Move them up in stages after molts, keeping fall distance low and the enclosure simple enough to maintain without chasing the spider.
Adult females should have a large, low terrestrial enclosure with deep firm substrate, a broad hide, fresh water, and enough open floor for turning and feeding. Use a catch cup before opening the enclosure for more than a quick water change.
Build the setup around:
- large low terrestrial enclosure
- 12-18 cm of compactable substrate
- wide cork hide or partly buried retreat
- stable water dish
- strong lid and clear maintenance access
💡 Lighting
No UVB or specialist basking lamp is required. A normal room day-night rhythm is enough.
Display lighting should be weak and cool. Bright lights can drive the spider into its retreat and can dry the moist layer faster than expected.
🌡 Heating and temperature
Use a daytime range around 22-27°C with a small night drop around 20-23°C. Stable room warmth is safer than overhead heat on a shallow terrestrial setup.
Avoid temperatures above the high twenties in small enclosures. Large New World terrestrials often tolerate a mild cool night better than a hot, dry retreat.
💧 Humidity and water
Aim for about 65-80% as a usable gradient, not as a permanently wet tank. Keep the water dish full, dampen one area, and let the surface around the main hide dry between maintenance days.
A dry top layer with a slightly moister lower layer is useful for a heavy terrestrial spider. Stale wet substrate encourages mites and mold, while chronic dryness can contribute to dehydration and bad molts.
🌿 Enclosure and decoration
Use compacted coco fiber, unfertilized soil mix, clay-soil mix, or another tarantula-safe substrate that holds a shallow burrow or hide edge. Anchor cork firmly so it cannot collapse onto the spider.
Avoid height, mesh that catches claws, stacked rocks, and heavy loose decor. A fall can rupture the abdomen of a large terrestrial tarantula, even inside a normal-looking display enclosure.
🪳 Feeding
Feed roaches, crickets, locusts where legal, and occasional worms sized to the spider. Juveniles can eat smaller prey more often; adults usually do well on a suitable meal every 7-14 days.
Strong feeding response is not a reason to overfeed. Keep the abdomen rounded, not ballooned, and remove uneaten prey quickly when the spider is in premolt or freshly molted.
🩺 Common problems
Common problems are overfeeding, falls, hair irritation, stale wet substrate, dehydration, mite blooms, and escape attempts during maintenance.
A spider that seals its hide may be in premolt rather than ill. Remove prey, keep water available, and do not dig it out unless there is a clear emergency such as flooding, injury, or severe collapse.
📌 Conclusion
Pamphobeteus sp. “Platyomma” suits keepers who want a large, impressive display spider and are comfortable managing provisional identity. Buy from traceable sources, keep the enclosure low and strong, and treat the trade label as data that needs preserving.
