Chaco Golden Knee (1-2cm)
This species is known to readily breed in captivity, the first recorded breeding was in the USA in 2000. Eggsacks are large containing 600 – 800 on average and spiderlings are good eaters and pretty bullet proof. However it is not a fast growing species but is compared to other Grammostola spp. They can reach are adult size at about 3 – 3.5 years where as a G.rosea would be a sub adult at this size at best.
Being recently described (but imported into the USA in 1998) this species is often incorrectly classified with a similar species Eupalaestrus campestratus (Pink Zebra) which comes from the same region. But the “Chaco Golden” can be distinguished by the absence of the swollen tibia on leg IV and possessing of very prominent and distinct golden markings on all legs. This species has two regional forms. One coming from Argentina that is less hairy than the one coming from Paraguay (R.Gabriel 2005). They may also be a third variation from Uruguay.
