[2] D. cyanochasma is characterized by its total length (including tail) of 70–90 cm (28–35 in) and slender physique, which gives it a comparatively small head and short fangs.

Adults engage in annual reproduction, typically occurring between mid to late spring and early summer.

The venom of the desert whip snake is primarily adapted to target smaller animals; so the zootoxin doesn't pose a significant danger to humans.

[5][3] The distinctiveness of D. cyanochasma was not immediately confirmed due to the challenges involved in collecting samples from remote locations, despite its widespread geographic range across the desert regions of Australia.

The species has been differentiated from other species through genetic research carried out by James Nankivell, a geneticist from the University of Adelaide and South Australian Museum honorary researcher Mark Hutchinson, in collaboration with herpetologists Brad Maryan and Brian Bush from the Western Australian Museum in Perth.
