Jumping spiders (salticids) are so diverse, it's difficult to choose how to organize and express all the different kinds. To convey what we've found in Borneo, let's start with shapes -- geometrical shapes.

First, the circle. Here are two round jumping spiders from our travels in Borneo. Pystira, which we called affectionately "the bumblebee", and Simaetha.

It's hard to find square jumping spiders, but here's my attempt. This is a male that I think is Porius.

Triangular jumping spiders? Both Uroballus and Ptocasius are triangular, with the abdomen ending in a point.

Triangle: Uroballus

A natural progression from circle to square to triangle might come next to line. Well, jumping spiders do have width, but these two are pretty thin. First, a male Viciria.

Next, a species I don't recognize, though it might be near Bavia. We call it the "clown" for its bold black and white markings. It lives on palm leaves.

Line: Unidentified, the "clown", possibly near Bavia

And finally, we arrive to a point. This tiny jumping spider may be related to Simaetha. It's a polished black color, and only about 1.5 mm long. It's bigger than the period at the end of a sentence, but not by much.

Point: Unidentified, possibly near Simaetha
