Jumping Spider

Pristobaeus sp.


I originally thought that this spider was Chalcotropis caeruleus, but a helpful comment from Francis Floe steered me in the direction of Pristobaeus sp. and a picture in looks very much like my specimen. The cephalothorax is black with striking white markings which bracket, and almost surround the lateral eyes. The anterior surface of the abdomen has a black stripe which narrows as it wraps round the lower sides. The dorsal surface starts white above the black stripe and this also wraps about half way round the sides and partially over the upper surface as it fades into yellowish brown. The spinnerets are white. The legs are almost entirely black with some metallic bronze showing through depending on the angle of view. All eight legs have small white patches on the femurs, near the knees.


I spotted this Pristobaeus sp. on the leaves of a Great Bougainvillea (Bougainvillea spectabilis) in our front yard. Like many Jumping Spiders, it did not appear to be startled or afraid of my presence and in fact jumped onto my hand and then my camera as I was trying to take some pictures.


My pictures appear to match a photograph of Pristobaeus sp. in I have now found some sources documenting Pristobaeus sp. as present in Philippines;- Also Related Spottings -

You're welcome John B. I've also seen a similar spider a few weeks ago and several Project Noah spotting in the Philippines documenting the same spider;

Hi Võ Anh Tuấn, Thank you for your help . I have been receiving so much help on this spider from Project Noah contributors. Everyone is so helpful. Thank you. I looked at the website you recommended and some others as well. I think this spider, for the moment, has to be noted down as Pristobaeus sp. Thank you again for your help.

Hi Francis Floe, you are so helpful thank you. I also found a source confirming the presence of Pristobaeus sp. in Philippines - So I feel more confident now that I am on the right track to eventually identifying the species. Many thanks again.

I found Pristobaeus listed in the Philippines on page 4 of this document
but no photo or exact species.

Hi Francis Floe, thanks once again for your very helpful advice. I obviously don't quite have the hang of Project Noah yet. I thought I had posted a comment thanking you for your help before I revised my spotting, but it doesn't seem to have worked. Sorry, I am sure I will get it right sooner or later !

Genus Pristobaeus looks very similar though I can't seem to find the exact species, all of them are only at the genus level.
But not a single species is listed in the Philippines on its Wikipedia page.
