What spider species is this?
It's one of the more unusual Jumping Spiders - similar, as Charles said above, to the North American spider Marpissa pikei, the Slender Jumping Spider (see second link below).  Yours is even thinner and more stretched out, but still clearly a Jumping Spider, from the long, heavy front legs and the big eyes on the front of its head.
Your species appears to be a spider called Mantisatta logicauda (first link below)
