Dorsally, greenish brown. Folio markings are slightly darker. Ventrally similar to female.[5]
Ecology[]
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 regions of Matale. It is highly restricted due to habitat destruction. The species is much more docile and not as aggressive as other tiger spiders. This makes it one of the popular pet spiders in the world.[5]
