Colour pattern

Body and appendages entirely white; eyes reddish.

Remarks

These two specimens possibly belong to Epimeria debroyeri sp. nov. However, they are much smaller (8 mm instead of 33 mm) and exhibit a number of differences, especially in the development of their mid-dorsal crests. It has to be noted that these differences might be size-related. The two specimens are therefore referred as E. cf. debroyeri .
