Similar in colour and markings to D. erythrurus but smaller and less elongate in shape.
The type material on which Blackburn 1800 based his description was 'taken by Mr. Jung on Yorke's Peninsula'. This is presumably A. Jung of Sunbury, near Yorketown who is reported in The Pioneer, 2 Jun 1899, p. 2 as donating a collection of 25 cockroaches to the SA Museum.
