The spider is of a bleak light red, with a reddish to whitish abdomen, and found out of doors in bird nests, under stones and under tree bark, also in webs of Amaurobius and Coelotes (two spider genera from the family Amaurobiidae).

It is very similar to the closely related O. domesticus, but has four tibial spine pairs instead of five.

Oonops pulcher has been identified from Europe to Ukraine, North Africa, and Tasmania, where it was introduced by man.

The subspecies Oonops pulcher hispanicus (Dalmas, 1916) is found in Spain.

The species name pulcher is Latin for "beautiful", referring to the oval eyes.
