Guatemalan Tiger Rump Tarantula
Davus pentaloris
Theraphosidae (Tarantulas), Order Araneae

Physical Description
A small-bodied, stocky tarantula with a distinctively round abdomen and thick legs. The body surface is covered in fine setae (hairs), and the abdomen features long, vibrantly colored urticating hairs. It exhibits a classic Mygalomorph body plan with downward-pointing fangs.
Size Estimate
Relatively small for a tarantula, with an adult leg span of approximately 3.5 to 4 inches (9-10 cm). This specimen appears to be a juvenile or sub-adult based on its proportions and size relative to the enclosure items.
Coloration & Markings
Distinctive black and orange/reddish striped pattern on the abdomen resembling tiger stripes. The carapace is typically a dark bronze or copper-black. The legs are dark with lighter beige or cream-colored banding at the joints.
Web Type
Terrestrial burrower and heavy silk producer. It does not spin an orb web but creates extensive silk tunnels and mats across the substrate and around its hide for protection and sensing prey.
Eye Arrangement
Small cluster of eight eyes located on a raised tubercle (the ocular turret) on the anterior mid-section of the carapace, typical of the family Theraphosidae.
Leg Characteristics
Stocky, hirsute (hairy) legs with noticeable light-colored banding at the joints. The legs are equipped with tarsal claws for climbing and scopulae (dense hair pads) for adhering to surfaces.
Venom & Safety Information
Venom Information
Possesses mild venom intended for paralyzing small insects. It is not considered medically significant to humans, generally comparable to a bee sting in terms of localized pain and swelling.
Medical Significance
Low danger level. The greatest risk to humans is the urticating hairs, which can cause skin irritation or severe eye/respiratory distress if inhaled. Bites are rare and usually only result in localized discomfort unless the individual has an allergic reaction.
Safety Recommendations
Use long forceps for feeding to avoid hairs. If relocation is necessary, use the 'cup and card' method. Always wash hands after touching the enclosure to avoid transferring urticating hairs to your eyes or face.
Habitat & Behavior
Habitat & Range
Native to Central America, specifically Guatemala and Mexico. In the wild, they inhabit tropical dry forests and scrublands, living in burrows or under fallen logs and debris.
Behavior & Temperament
Generally skittish and fast but not typically aggressive. As a New World tarantula, its primary defense is kicking urticating (irritating) hairs from its abdomen rather than biting. They are active hunters and prolific 'webbers' in captivity.
Diet & Prey
Insectivorous, feeding on crickets, roaches, mealworms, and other small invertebrates. They utilize vibrations in their webbing to detect prey and then use a burst of speed to subdue it with their fangs.
Seasonal Activity
In its native habitat, activity peaks during the rainy season when prey is abundant and males roam to find mates. In captivity, they remain active year-round if temperatures are maintained.
Description
The Guatemalan Tiger Rump is a stunning miniature tarantula prized for its 'tiger-striped' abdomen and intricate silk-spinning. Unlike larger tarantulas, it remains manageable in size, making it a favorite for arachnoculturists. Its active nature and tendency to heavily landscape its environment with silk provide a fascinating glimpse into terrestrial spider behaviors.
Key Features
Bold orange/red and black tiger-stripe abdominal pattern, metallic copper carapace, and light banding on leg joints.
Similar Species
Davus fasciatus (Costa Rican Tiger Rump), which was previously confused with this species but has slightly different leg banding and geographic origin.
Life Cycle
Females can live up to 10-12 years, while males have much shorter lifespans and die shortly after reaching maturity (approx 3-4 years). They reproduce via egg sacs that can contain several hundred spiderlings.
Ecological Importance
Acts as a vital population controller for insects and other invertebrates within its ecosystem. It also serves as a food source for larger predators like birds, lizards, and small mammals.
Conservation Status
Not currently listed by the IUCN, but like many tarantulas, they faces threats from habitat destruction and the illegal pet trade. Most seen in the hobby today are captive-bred.
Interesting Facts
Despite their small size, they are very bold predators. They are one of the most prolific silk-producers among terrestrial tarantulas, often covering their entire habitat in a 'winter wonderland' of webbing.
Photography Tips
Shoot from a low angle to capture the abdominal stripes. Use a macro lens to highlight the texture of the setae. Soft, diffused lighting is best to avoid glares off the silk or the carapace.
