About the species

Venezuelan Suntiger (Psalmopoeus irminia) is an arboreal tarantula whose accepted World Spider Catalog distribution includes Venezuela, Guyana, and Brazil. Adults usually reach about 12–14 cm in leg span. The abdomen and legs show a contrasting, often fiery orange pattern on a darker background. Geographically this is a New World species, but like other Psalmopoeinae it lacks typical urticating hairs; defence relies on speed, a web retreat, and a readiness to bite.

Care at a glance

  • Size

    Leg span approx. 12–14 cm

  • Enclosure type

    Vertical, for a fast arboreal species

  • Substrate

    A moderate layer; the surface may dry, the lower parts slightly more humid

  • Furnishings

    Vertical cork or branches for webbing, a retreat above the substrate, and constant access to water

  • Conditions

    Moderate; very good ventilation, without a stuffy, constantly wet atmosphere

  • Characteristics

    A fast arboreal species without urticating hairs, requiring careful handling of the enclosure

Care and behaviour

Psalmopoeus irminia spends most of its time in webbing built on vertical surfaces, often in a bark crevice or in the upper corners of the enclosure. The tank should be tall, tight-fitting, and fitted with stable structures for silk. Substrate does not replace the retreat; the spider may still come lower, especially as a juvenile.

Conditions should be moderate, with clear ventilation. A slight moisture gradient (drier surface, slightly moister lower layers) is safer than constantly misting the entire décor. Fresh water in a dish is constant, even when the web looks dry.

The species moves fast and may leave the retreat abruptly. It is not a typical calm terrestrial tarantula for beginners, though it is often rated intermediate rather than extreme. Service work should be planned, with the surroundings secured and without attempts to pin the animal for long.

Good to know

Psalmopoeus irminia lacks the urticating hairs typical of many New World terrestrial Theraphosinae. Defensive behaviour resembles Old World tarantulas: a fast run and a bite. Venom is catalogued as medium — stronger than in many slow terrestrial species, but not in the same class as the most potent arboreal Poecilotheria. The species is not listed on the CITES Appendices; local rules may still apply. This page is not legal advice.
