Found under rocks, in riffles of moderately large rivers (30-50m) in the savannah zone, in areas where there is a strong current (>1m/sec); in all sites where collection took place, there was a rather restricted gallery of shrubs and small trees on the river banks; water was greenish with a transparency of about 50 cm, neutral pH (6.5-7.5), with a high content of dissolved oxygen (6.5-7.5 mg/l) and a rather low conductivity (35-45 µS/cm); water temperatures were between 23 and 25 °C at noon (Ref. 26632).
