Tliltocatl albopilosus ( Syn .: Brachypelma albopilosum ), rarely alsocalledthe curly haired tarantula , is a Central American tarantula from the genus Tliltocatl . Its distribution area are the states of Costa Rica , Venezuela , Guatemala , Nicaragua and Honduras . In Nicaragua it is very numerous and is considered a cultural follower .
Appearance
The spider has a dark brown basic color and has a slightly golden sheen on the carapace. The legs, probes, and opisthosoma have light brown, curled hair. Adult females are approx. 8 cm long (measured from the bite claws to the spinnerets). She has abdominal stinging hairs on the opisthosoma, which she can wipe off with her hind legs in case of danger or work into the web as protection against predatory noses.

behavior
It digs holes in the ground close to the ground or hides under fallen pieces of bark or roots. This spider behaves calmly, unimpressed or slightly defensive towards humans. Throwing abdominal stinging hairs against the alleged attacker is chosen as a popular defense method. A bite is extremely rare and is unlikely to cause any reactions.
Ingestion
For food, this spider takes all sorts of small animals from insects to small rodents. The prey is kneaded in the living tube with the biting claws and dissolved with the poison and digestive secretions. The food pulp is then absorbed through the slit-shaped mouth opening. During this process, the spider repeatedly lays the prey on a spun feeding carpet and spins threads over it. What exactly is the purpose is unknown. Possible explanations start from better digestibility of the prey up to a slight disinfection of the prey by antibiotic components of the spider silk.
Reproduction
After moulting, the male spins what is known as a sperm web, a web between two objects or walls that are close together. This is an auxiliary construct for the uptake of the semen into the secondary sexual organ, the globe . The male first crawls under the sperm net and places a sperm drop from his primary genital opening in the abdomen below the auxiliary net. Then it runs above the net and sucks the drop into its bulb at the end of the button.
Finally, there is a bridal show in the area and courtship in its species or genus-typical way. This is a drumming of the buttons on the floor and rhythmic movements of the whole body, which can be perceived by the sensory hair on the body of the female as sound waves across the floor. If there is a female around, she will respond accordingly. As the male ages, it loses the ability to courtship correctly and is then no longer recognized by the female as a separate species and mistaken for prey. Hungry females try to eat the male after the sexual act. Although this is a rarity in tarantulas, it is relatively common in Tliltocatl species.
The fact that the courtship signals are very similar among Tliltocatl species is proven by many successful crossbreeding attempts under artificial conditions.
Since the males are actively looking for a female and migrate a large radius, they also fall prey to predators or road traffic more quickly.
One cocoon contains up to 600 eggs.
Terrarium keeping
Like many Tliltocatl species, this spider is also kept in terrariums. She is considered a very simple, not too demanding pupil who can also be easily drawn. There are often hybrids between this species and the black and red tarantula in terrariums .
