Species description

Geographical Origin and Habitat: Endemic to the state of Veracruz in eastern Mexico. It inhabits dry forest zones and semi-humid scrublands, excavating burrows or seeking shelter under fallen logs and rocks.
Taxonomy and Genetics: Belongs to the family Theraphosidae, genus Tliltocatl (formerly grouped under the genus Brachypelma). It is closely related to the popular Tliltocatl albopilosus.
Behavior and Habits: Terrestrial, very docile, and slowly-moving species. It is rarely defensive and does not easily bite, preferring to retreat into its burrow or kick urticating hairs when threatened.
Morphology: A medium-sized tarantula, reaching a body length of 5-6 cm and a leg span of 12-14 cm (around 5 inches). Features a velvety black coloration on its carapace and legs, with distinctive red or orange hairs covering the abdomen.

Care, breeding and tankmates

Terrarium Setup: A standard terrestrial terrarium of 12x12x12 inches (30x30x30 cm) is perfect. Provide a deep substrate layer (3-4 inches / 8-10 cm) of dry coconut fiber or peat moss to facilitate burrowing. Include a cork bark hide.
Lighting and Heating: Maintain temperatures around 24-26°C (75-79°F) during the day, with a drop to 20-22°C (68-72°F) at night. No specialized lighting is necessary.
Humidity and Hydration: Moderate humidity (60-70%). Mist one corner of the enclosure weekly and let it dry out before misting again. Provide a small, shallow water dish.
Feeding and Supplementation: Feed appropriately sized crickets, roaches, and mealworms. Adults should be fed once a week; spiderlings require more frequent feeding. No supplements are needed.
Compatibility: Strictly solitary. House individually to prevent fatal cannibalism.
Health and Common Diseases: Exceptionally hardy species. The primary danger is physical damage to the abdomen from falls, so do not provide high climbing areas. Keep the substrate dry to avoid mold.
