Xenesthis immanis
A large terrestrial tarantula, black overall with a reddish sheen on the carapace and light brown setae on the abdomen. Leg span reaches 25cm. It readily kicks urticating hairs and is seldom bred in captivity.
Xenesthis immanis was described by Ausserer in 1875 as Lasiodora immanis, included in Xenesthis when Simon erected the genus in 1891, and given its current combination by Pocock in 1901; it is the type species of the genus. The male type came from around Bogota in Colombia and the female from around Caracas in Venezuela. It is terrestrial, digging silk-lined burrows in banks and roadside slopes and waiting at the entrance for prey from dusk onwards. If cornered it responds with a threat posture, a bite or its urticating hairs. It is known for tolerating the tiny frog Chiasmocleis ventrimaculata in its burrow rather than eating it, and a mutualism has been proposed in which the spider protects the frog while the frog protects the spider's eggs from ants. Successful captive matings are uncommon, and most animals in trade are wild caught.

Large live insects such as crickets and roaches
Its habitat is rainforest from Central to northern South America, and conditions should approximate that.
Being large, it needs a correspondingly big enclosure. It burrows into banks in the wild, so provide deep substrate and a hide.
It ambushes prey at the burrow entrance from dusk. Offer large live prey such as crickets and roaches when it becomes active.
It is easily irritated and an effective hair-flicker, and if cornered it will threaten or bite, so it is not a species to handle.
Successful captive matings are uncommon and most traded animals are wild caught, so check provenance when buying. Two to three months after mating the female withdraws into her burrow and builds an egg sac about a month later; some 50-100 spiderlings emerge after roughly five weeks.
Advanced. This is an advanced-level species. It requires specialized equipment and advanced husbandry skills with precise environmental control.
The average lifespan of Colombian Lesser Black is Females 12-15 years, males 3-4 years. With proper care and nutrition, they can live a long and healthy life.
Colombian Lesser Black typically reaches Body 7-10cm, leg span 19-25cm as an adult. Size may vary depending on care conditions and individual genetics.
