Psalmopoeus irminia, also known as the Venezuelan suntiger, is a species of tarantula endemic to Venezuela, Guyana and Brazil.

Psalmopoeus irminia are unique in their striking black coloration paired with vibrant orange chevron and leg markings.

They are distinguished from true spiders by their two pairs of book lungs, vertically oriented chelicerae, and urticating setae.

However, like all members of Psalmopoeus , P. irminia lack these urticating hairs but make up for it by having stronger venom compared to other New World tarantulas.

P. Irminia do not acquire urticating hairs, so they depend heavily on their fast reflexes and venom to protect themselves.

As P. Irminia goes into premolt, they will begin fasting, seek moisture, shed their abdomen hairs, and their skin will darken.

When they begin to shed, the tarantula will lay on its back and slowly remove its exoskeleton; this process usually happens overnight but can take up to 24 hours.

P. irminia have a diet that mainly consists of invertebrates such as crickets or cockroaches that are caught at the entrance of their burrow or their immediate surroundings.

They use the hair on their legs to sense vibrations, allowing them to catch their prey easier.

Tarantula bodies can be divided into two parts, the cephalothorax (prosoma) and the abdomen (opisthosoma).

The cephalothorax is the head and thorax, it holds the stomach, eyes, nervous system, venom, and digestive fluid reservoirs.

Although they have 8 eyes, they have poor eyesight and can only detect contrasts between light and dark, which is why their hairs are so important.

[4] Tarantulas have 8 legs and each foot ends with a cluster of bristles called scopulae and a pair of tarsal claws.

Females can accept more than one male throughout the breeding season, which takes place between late September and early October.

The male will proceed by forcing the female's body upward and locking her fangs together with his tibial spurs.

The male will insert one palp in the epigastric furrow and the other in the epigyne and deposit his sperm.
