The type locality, Paramaka Creek, is a medium sized and shallow stream with 3-7 m width, less than 50 cm depth, pools and some riffle habitat, a rocky substrate, and bordered by terra firme rainforest. Its water was transparent with a mean pH of 6.26, conductivity 24.2 μS/cm and temperature 23.2°C. Collected together with several Harttiella crassicauda (Ref. 116863).
