A restricted distribution area around Song Mahi at the foot of the Ngovayang Hills. They were found in the Nyong River drainage.

Small brooks. Known to inhabit shallow water between 1 - 5 cm.
The type locality was a clear, fast flowing stream with a soil base & was well shaded. They have also been found in a pool 40 x 40 cm with a depth of 8 cm near this location. Air temperature at 10.00 hrs on the 28th July 1977 was 23·5°C, pH 6·5.
In a locality 2 km further down the road from the type locality in a pond adjacent a flowing stream the sp. E.infrafasciatus (then thought to be baroi), A.loennbergi, Barbus sp. & Mormyrid sp. were also found.
