Blue-thighed Salticid Spider

Size 3mm, generously measured. This is a small jumping spider. It was even dwarfed by some small ants. So funny to see their reaction when an ant bumps into them, a bit like a cat who forgot that a mouse is prey not something to be scared of and jumping away from. I could not find an adequate match on the web resources I normally use. I assume it is either a juvenile or a not-very-common species. It was found in a private garden on a tree, probably a gum tree. The tree has a known population of ants that is frequently visited by wasps etc. and that inhabits some rotten cut branch stump. That is actually the area this spider seemed to be checking out, shortly before darkness. The front legs of this jumper are quite long and thick, often held up. I always get excited thinking it might be a scorpion (which I have never seen in real life). All the legs are banded, look somehow distorted. The thighs of the front legs shine blue. This is quite visible. The spider is quite fast and doesn't rest for long. It blends in so well with the background. When it felt that I harrassed it too much with my camera and flash, it took a defensive stance, showed me the white pom-pom palps and her impressive conical mandibles behind it. From further away, it looks like the spider is flashing when it waves its palps. When moving I think they are flapped back, and only the brown bits are visible. The thorax seems quite slim, multicoloured, but not a really obvious pattern. Eye pattern are typical salticid but don't actually help me to identify the species. The abdomen seems to have two whitish-dot, but is also quite inconspicuous. With small animals often it is difficult to get good representative photos. I will keep looking for an identification, but am not very confident, that I find one, if there is one. Update 8/8/2017: Yesterday, I found what I believe could be the same species. It was 3mm in size. It was totally dark and hardly visible on the gum tree bark. Sometimes, it was moving its white palps in quite a nervous manner as if to attract prey. There were quite a few white starfish-looking eggs suspended on a few threads that could actually belong to this spider.
