Poecilotheria hanumavilasumica

🔤 Taxonomy

Poecilotheria hanumavilasumica is the currently accepted scientific name. Smith described the species in 2004, and later literature lists Rameshwaram Island, India, as the type locality.

English common names used in the hobby:

• Rameshwaram ornamental tarantula

German common names used in the hobby:

• Rameshwaram-Schmuckvogelspinne

📌 Description

Poecilotheria hanumavilasumica is an arboreal Old World tarantula from India, known for its striking ornamental pattern and localized distribution. It is one of the more specialized Poecilotheria species in collections and is valued for both beauty and rarity.

Adult size is usually about 6-7 cm body length and about 18-22 cm legspan, with females typically heavier than mature males.

Like other Poecilotheria, it is fast, defensive, and not suitable for regular handling.

Because of its more localized reputation and relative rarity in collections, many keepers prefer a conservative setup with minimal disturbance and clear record-keeping.

☠️ Venom

Poecilotheria hanumavilasumica should be treated as a medically significant tarantula. A bite can cause intense local pain, swelling and, in some cases, wider symptoms such as muscle pain, cramping, nausea, dizziness or prolonged discomfort.

There is no hobby-level antivenom plan for this species. Keep hands out of the enclosure, use tools and catch cups, and get medical advice for severe pain, spreading symptoms, breathing trouble, allergic reaction, or bites to children or vulnerable people.

🌍 Distribution

Poecilotheria hanumavilasumica is native to southeastern India, with field records also reported from northern Sri Lanka. In the wild it is associated with warm coastal and lowland arboreal habitats with tree cavities and bark retreats.

For enclosure design, the important takeaways are:

• a secure vertical enclosure with cork bark or tree-bark retreats
• strong cross-ventilation with moderate humidity
• fresh water and occasional moisture without stale air
• minimal disturbance around the main retreat
• careful maintenance, because fast arboreal species can bolt quickly

⚖️ Legal status

Poecilotheria hanumavilasumica 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. Local rules on import, sale, breeding, transport, exhibition, and documentary proof of legal origin may still apply, so keeping invoices and origin records is advisable.

🤌 Husbandry

Poecilotheria hanumavilasumica should be housed alone in a secure vertical enclosure.

Young spiders should be raised in secure, simple containers first, with larger housing introduced only when they can use the extra space safely.

Stage management is different from terrestrial species. Slings and small juveniles should be kept in smaller, well-ventilated vertical containers where prey can be found and the retreat stays secure. Adults need taller, escape-proof enclosures with a dependable bark retreat and a clear maintenance plan, because large Poecilotheria are fast, defensive, and difficult to manage safely during rehousing.

Keep the setup simple and dependable:

• Tall setup with vertical retreats
• Cork bark or tree-bark hide
• Strong ventilation
• Water dish
• Minimal disturbance

This species should be given a retreat it can trust and use repeatedly. Repeated rehousing or frequent enclosure changes often create more stress than benefit.

💡 Lighting

Keep lighting simple: ordinary room light and a consistent day-night cycle are enough.

Bright direct lighting is unnecessary for routine care.

🌡 Heating and temperature

Practical temperature targets are:

• Daytime: around 24-28°C
• Night: slight drop acceptable

Moderate stable warmth is preferable to aggressive heating.

💧 Humidity and water

Poecilotheria hanumavilasumica does best with moderate humidity, fresh water, and strong airflow. The enclosure should not remain stagnant or overly wet.

Useful principles include:

• Fresh water always present
• Slightly more moisture in one area if needed
• Ventilation strong enough to prevent stale air
• No permanently wet enclosure

🌿 Enclosure and decoration

Use a vertical enclosure with secure bark retreats and enough space to climb. Height, ventilation, and retreat security are more important than heavy decoration.

Simple stable decoration is usually best. The enclosure should be easy to service without tearing apart the spider’s main retreat.

🪳 Feeding

Poecilotheria hanumavilasumica is insectivorous. Suitable prey includes:

• Crickets
• Roaches
• Locusts where available
• Mealworms only in moderation

Young spiders can be fed more often, while adults usually need a 7-14 day rhythm adjusted to abdomen size, recent molts, and prey size.

If the spider seals itself in or shows clear premolt behavior, prey should not be left inside to wander.

Adjust feeding to stage and body condition. Growing slings may eat often; adults usually need longer gaps. Remove prey during premolt and reduce feeding if the abdomen stays overfull.

🩺 Common problems

Common problems include dehydration, poor ventilation, stress from frequent disturbance, and falls in inappropriate enclosures.

Warning signs include lethargy, weak feeding response, repeated frantic movement, and difficult molts.

When troubleshooting, check ventilation, water access, retreat security, and recent disturbance before changing multiple variables at once.

📌 Conclusion

Poecilotheria hanumavilasumica is a beautiful localized arboreal ornamental tarantula best suited to keepers who can provide secure vertical housing and calm maintenance. Stable warmth, airflow, and retreat quality are the essentials.
