Poecilotheria smithi, or the yellow-backed ornamental, is a species of large arboreal tarantulas. It is endemic to Sri Lanka and considered to be critically endangered.
Size
The female is much larger than male, with a head-to-body length of 6–7 cm. The figure for the male is 4–5 cm.

The species can be distinguished from other tiger spiders by all black leg parts (coxa, trochanter, femur) with prominent brushes on the femur.
Description

Ecology
The yellow-backed ornamental is one of the rarest tiger spiders found on the island, where it is confined to the Haragama area in Kandy, with very few sightings from the region of Matale. It is highly restricted due to habitat destruction. The species is docile and not as aggressive as other tiger spiders. This makes it one of the popular pet spiders in the world.
