They have two prominent spinnerets that are almost as long as their abdomen, earning them another nickname, the "two-tailed spiders".

Rather than using a web that captures prey directly, they lay a light coating of threads over an area of tree bark and wait for an insect to stray onto the patch.

[3] It has a global distribution in tropical and subtropical regions, with only a few species being found north of the 40°N parallel.

All members are ecribellate (lack the cribella or perforated plates which produce multiple, exceptionally fine strands of silk) and are recognizable by the pair of exceptionally long spinnerets set at the tip of the abdomen.

They are very well camouflaged when stationary on the trunk of a tree and aligned with the bark markings.
