These unusual Jumping Spiders of the sub-family Spartaeinae have a different eye arrangement compared to other Jumping Spiders.
Whereas the posterior median eyes (i.e., the eyes in the second row) of most Jumping Spiders are tiny, there is a category of Jumping Spiders whose posterior median eyes are fairly big. These include spiders in the genera Cocalus, Phaeacius, Portia and Spartaeus.
