The upper part of the Rio Perdido is situated on a carbonate plateau of about 68 km long located at the southern margin of the Brazilian Pantanal Wetland denominated Serra da Bodoquena (Bodoquena Ridge). This river drains a carstic region and has a 2 to 3 km long underground section. In the plateau, the river is dammed by calcareous tufa deposits, which form 1 to 6 meter tall sequences of waterfalls. The dammed section can be as deep as 12 meters, with vertical rock banks and very slow flow. The substrate has many logs, branches and whole trees lying on whitish calcareous clay. During the rainy season, the augmented flow disturbs the clay and the water transparency, which is usually great, is significantly reduced.</paragraph>

Specimens were collected in stretches with sluggish to still waters. Underwater observations were made while collecting, for a total of some 20 hours of scuba diving by two of the authors (MRC and OF) and two helpers. The species seems to be present in low densities, with only a few adult individuals observed at any time. Active adult individuals were observed from dusk to around 21:00, from near the surface to a depth of 2 meters, and always alone. After this time they could be seen resting along the vertical rocky banks. During daylight hours they remain hidden and were not seen. Young specimens, at least up to 50 mm SL, were observed in activity during the day on two occasions, in small groups (5-6), mingled with schools of
