Theridiosoma

The carapace ranges from dark brown to light tan, sometimes with distinct markings around the eye region or fovea, The sternum is smooth, with sparse bristles, and is usually darker towards the margin.

The abdomen is ovoid in shape, and taller than wide or long; the dorsal side of the abdomen often bears a light, thin median band and/or symmetrical light spots, the ventral side is dark.

As with other spiders in the family, the tibiae of the 3rd and 4th legs bear a group of long, vibration-sensitive trichobothria.

[5] Their preferred habitat is typical for the family; they construct a web in wet, shaded understories of forests,[4] All species construct a vertical orb web in dark, damp places.

At the end of web construction, the radial threads are fused at the centre so that only four, the "rays", reach the hub.
