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).

在稀树草原区中的普通大河 (30-50 公尺) 的急流中,发现于岩石之下了, 在区域中在哪里有一个强的水流.(>1 公尺/秒) 在所有的收集发生了的位置中,在河岸上有一个相当限制的灌木走廊与小的树。 水是呈绿色的透明度大约 50 公分 , 中性酸硷度 (6.5-7.5), 具有一个高的溶氧量 (6.5-7.5 mg/l) 与一个相当低的导电率 (35-45 μ S/公分) 的内容. 水温中午在 23 与 25 °C 之间。 (参考文献 26632)
