Range Description

Hypsiboas nympha is distributed in the western Amazon Basin. Specimens reported in the original description originate from the northern and southern regions of eastern lowland Ecuador and from northeastern Peru at elevations below 600 m, and from lowlands of Colombia around Leticia. The northernmost locality of H. nympha is "Singue", province of Sucumbıos, Ecuador, whereas the southernmost record is Leticia, Colombia. The species probably also occurs in adjacent western Brazil (Faivovich et al, 2006).

Habitat and Ecology

Hypsiboas nympha appears to prefer primary lowland forests flooded by white and black waters, and is occasionally found in lowland nonflooded (terra-firme) forests. The type locality is a swampy area (water depth 5–20 cm), approximately 50 m distance from a stream. The arboreal vegetation at the type locality includes species of the families Verbenaceae, Lauraceae, Arecaceae, Bombacaceae, Actinidiaceae, and Rubiaceae, with stem diameters up to 450 mm; poor herbaceous coverage and an average canopy height between 12–23 m (emergent trees up to 40 m). The general topography of the type locality consists of low hills with flat or slightly rounded tops and slightly convex slopes; the lowermost areas were flooded. Other hylids collected at the type locality of Hypsiboas nympha are Dendropsophus leucophyllatus, D. marmoratus, D. miyatai, Hypsiboas boans, H. calcaratus, H. fasciatus, H. geographicus, H. granosus, H. lanciformis, Osteocephalus cabrerai, O. planiceps, O. taurinus, O. yasuni, Scinax ruber, and Sphaenorhynchus lacteus (Faivovich et al., 2006). In other localities (e.g., Tiputini Biodiversity Station) the species has been found in small slow rivulets amidst the low riverine vegetation.

One female of H. nympha was found to contain ca 70 unpigmented oviductal eggs of ca. 2 mm (Faivovich et al., 2006).

Population

No population status information is available for this species; however, the species is relatively uncommon in most areas where it has been recorded (D.F. Cisneros-Heredia, pers. comm. 2008).

Population Trend

Unknown

Major Threats

Although the species has a widespread distribution, several areas of its current distributional range are severely affected by deforestation produced by colonization and the uncontrollable extension of the agricultural frontier (e.g., Limoncocha and Cuyabeno areas in northeastern Ecuador and Iquitos surroundings in northern Peru) and by contamination of water sources due to residues of oil extraction (e.j. Cuyabeno area in northeastern Ecuador)(D.F. Cisneros-Heredia, pers. comm. 2008).

Conservation Actions

The species is known to occur at Reserva de Produccion Faunıstica Cuyabeno and Yasuni National Park (Ecuador), as well as within the realms of Tiputini Biodiversity Station (Ecuador), and the Gueppi Reserved Area and Allpahuayo-Mishana Reserved Area (Peru) (Faivovich et al., 2006).

Taxonomic Notes

Placed in the Hypsiboas benitezi group in the original publication. Hypsiboas nympha is distinguished from other similar species by a combination of morphological and molecular features and colour patterns (Faivovich et al., 2005, 2006).
