The spiders have been recently described by arachnologist, Dr Helen Smith and colleagues Dr Barbara Baehr, Queensland Museum and Dr Mark Harvey,Western Australian Museums.
Many species in the genus Cavisternum can be told apart by the extent of the concave area on the sternum of males and the pattern of modified setae. The sternum of C. ewani is quite spectacular, being almost entirely covered.
This species is widely distributed in drier areas of eastern Queensland. We know little about the habits of these spiders except they are likely to be free-living ground hunters.
