Pellenes seriatus is a species of 'jumping spiders' belonging to the family Salticidae.

The adults of these spiders reach approximately 6–7 millimetres (0.24–0.28 in) of length and can mainly be encountered on the bark of trees, on sunny rocks and in grasslands.

The males of this species frontally look very similar to Pellenes lapponicus and to Hasarius adansoni.

In males the basic color of the hairy body is black, with a white longitudinal stripe on the middle of the opistosoma and a bright red mask on the eyes.

The pedipalps have whitish tips, while the legs are wholly black.
