EtymologyThe specific name cyanochasma is modified from the Greek words kyanos meaning blue and khasma meaning space or expanse, alluding to the bluish grey anterior body colour of this species and reference to its distribution filling the geographical space between D. psammophis and D. reticulata. Used as a noun in apposition.
