Description
Ursa are small spiders with a pear-shaped carapace and eyes in two rows. The anterior and posterior median eyes are close together, while lateral and anterior median eyes are larger than posterior lateral eyes. The abdomen is round and decorated with faint whitish markings. The legs are the same colour as the carapace, with leg IV being the shortest and leg I having rows of lined setae.[3]
Life style
Nothing is known about their behaviour, with some specimens sampled while sweeping grass.[3]
