There is considerable variation in the appearance of the species presently accepted as Australian cyatholipids. The main characteristic of all cyatholipids is a broad slit-like tracheal spiracle (the entrance to its 'breathing' network) on the underside of the abdomen in front of the spinnerets. Unfortunately, this can only be seen with the aid of a stereo microscope. The shell-like upper surface of the abdomen with its coarse and relatively upright hairs is diagnostic for Matilda species.

Spider(s) with a very similar appearance: None.
