This species is known from Gabrielle and Kaw Creek in north-eastern French Guiana (Lescure and Marty 2001), and is likely to occur more widely. A dot-map of the distribution is presented in Lescure and Marty (2001). It occurs at very low altitudes, up to only about 10m asl.
Habitat and Ecology
This species inhabits marshes in lowland rainforest and has not been found in disturbed areas. It presumably breeds in water.
It is not thought to be a common species. It can be found relatively easily after heavy rains but otherwise it can be very difficult to locate.
Its major threats are unknown, but most of the known range is within a protected area, so there are not expected to be any major threats to this species' habitat at present.
The protected area within which this species is found is Kaw Nature Reserve.
The reference of Lescure (1976) refers to this species as S. rostratus.
