Poecilotheria tigrinawesseli

🔤 Taxonomy

Poecilotheria tigrinawesseli is the currently accepted scientific name. World Spider Catalog treats Poecilotheria chaojii as a synonym of this species.

English common names used in the hobby:

  • Wessel’s tiger ornamental
  • Anantagiri’s parachute spider

📌 Description

Poecilotheria tigrinawesseli is a fast arboreal Old World tarantula from India. It is kept for display, not handling, and the enclosure has to be designed around speed, medically significant venom, and reliable paperwork.

Adults are usually about 15-20 cm legspan. Females are heavier and long-lived; mature males become slimmer, restless, and short-lived after maturity.

This is an expert species. A calm individual is still capable of explosive movement, defensive threat posture, and a serious bite.

☠️ Venom

Poecilotheria bites should be treated as medically significant. Reported effects can include intense pain, swelling, muscle cramps, nausea, dizziness, and prolonged discomfort.

Do not handle this species. Use catch cups, long tools, a closed work area, and planned rehousing containers. Seek medical advice after serious, spreading, allergic, respiratory, or persistent symptoms.

🌍 Distribution

World Spider Catalog lists Poecilotheria tigrinawesseli from India. Care should reflect Indian forest and woodland tree retreats, including records associated with the Eastern Ghats region.

In captivity this means a secure vertical retreat, cross-ventilation, clean water, and a moisture gradient that does not turn the enclosure into a sealed wet box.

⚖️ Legal status

Poecilotheria tigrinawesseli is covered by the CITES Appendix II listing for Poecilotheria spp. In the EU wildlife trade system, Poecilotheria tarantulas are treated under Annex B rules. The species is not relevant to the Bern Convention because it is not native to Europe.

Keep purchase invoices, breeder details, import or transfer paperwork where relevant, and records that connect the animal to a lawful source. Local rules on ownership, import, sale, transport, exhibition, breeding, and proof of legal origin may still apply.

🤌 Husbandry

Keep Poecilotheria tigrinawesseli alone except for a controlled breeding introduction.

Spiderlings can start in small secure arboreal containers with bark and ventilation. Adults need a vertical enclosure around 30 x 30 x 45 cm or larger, filled with usable cork, bark, and anchor points.

Useful adult priorities:

  • escape-proof vertical enclosure
  • cork tube or vertical bark slab
  • strong cross-ventilation
  • water dish or reliable water access
  • door layout that blocks sudden bolting

💡 Lighting

Normal room lighting is enough. UVB and hot basking lamps are unnecessary.

Use indirect display light only. Bright heat above the retreat can dry the upper webbing and force the spider into exposed movement.

🌡 Heating and temperature

Aim for about 23-27°C by day, with nights around 20-23°C. Avoid a hot basking spot.

If extra heat is needed, warm the room or one side gently under thermostat control. The spider must be able to leave the warmest area without leaving its retreat.

💧 Humidity and water

Aim for about 65-80% as a ventilated gradient. Keep water available and maintain some moisture reserve without keeping the enclosure sealed or wet.

Good airflow matters as much as humidity. Condensation, mold, and a sour smell mean moisture is outpacing ventilation.

🌿 Enclosure and decoration

Use cork tubes, vertical bark slabs, branches, and foliage to create private routes from floor to top. The retreat should let the tarantula disappear completely.

Avoid wide mesh, loose heavy decor, large door gaps, and layouts where the spider sits directly on the opening path.

🪳 Feeding

Feed roaches, crickets, locusts where legal, and occasional soft larvae. Adults usually do well with suitable prey every 7-14 days.

Offer prey near the retreat and remove uneaten insects before molts. Do not use vertebrate prey.

🩺 Common problems

Common problems include escape during water changes, stale wet air, dehydration, stuck molts, fall injuries, overfeeding, and rushed rehousing.

Most incidents happen during routine access. Design the enclosure so water, prey, and maintenance can be managed without chasing the spider.

📌 Conclusion

Poecilotheria tigrinawesseli suits experienced keepers who can manage a secure arboreal setup, conservation paperwork, and no-contact maintenance. Buy only from traceable legal sources.
