The only depressa in NSW that got DNA tested were some in collections of a couple of keepers only a few years ago, after licensing authorities were suspicious of their origin.
As epsisolus exists only after the recent break up of the depressa complex, previously all Pygmy spiny tailed skinks (E.depressa) were under the one name. Keepers have traditionally referred to them as either the browns or reds.
There are more in collections than people think.
