Description
The total length female and male is 8-10 mm.[3]
The genus is recognised by the triangular shape of the abdomen. When resting, the legs are pulled close to the body. Their color varies from yellow orange to brown. The carapace pear-shaped.[3]
The eye area is narrowed, more so in males. The median eyes are grouped together with posterior median eyes larger than anterior median eyes. The lateral eyes are positioned more to the back and close together. The fovea is longitudinal.[3]
The abdomen is triangular and anteriorly truncated. The front legs are strong with strong setae on the tibiae.[3]
Life style
They make orb-webs at night, but little more is known about their behaviour.[3]
Species
