The new species was collected from a small stagnant pool a few square meters in area and about 1 m in depth, located in a wet passage some 500 m from the main entrance of Krem Khung. The pool bed is mostly sandy with scattered pebbles. The water was clear, pH 8.6, and a very low D.O. of 1.1 ppm when analyzed in the month of April 2015. No other macrofauna were recorded inside the cave except weakly-pigmented crabs and crayfish, crickets, cockroaches and millipedes.
