Range Description

Ischnocnema henselii occurs in the subtropical Atlantic rain forest and parts of the Araucaria forest domain in southern Brazil (northeastern Rio Grande do Sul and coastal mountain range of southeastern Santa Catarina), Misiones, Argentina, and probably southeastern Paraguay (but see Brusquetti and Lavilla, 2006), at altitudes from about sea level up to 1200 masl (Kwet and Solé, 2005).

Habitat and Ecology

Ischnocnema henselii lives on mountain slopes with subtropical Atlantic rain forest and in Araucaria forests on the margin
of the Araucaria plateau. It is a ground-living species with diurnal and nocturnal activity. During the breeding season (October to January) males call at night, rarely during the day, on the ground or from fallen trees and stones. Calling activity increases during warm periods with rainfall. Eggs are deposited terrestrially, below trunks or stones. One female was found to have 26 large (3 mm diameter) and 45 small (1 mm diameter) yellowish eggs (Kwet and Solé, 2005).

Population

This is considered to be a common species (A. Kwet, pers. comm. 2008).

Population Trend

Unknown

Major Threats

No major threats are known for this species.

Conservation Actions

The species is known to occur in several protected areas, i.e. Parque Nacional de Aparados da Serra, Parque Nacional da Serra Geral, Parque da Ferradura and Parque Caracol (A. Kwet, pers. comm. 2008).

Taxonomic Notes

Allocated to the genus Ischnocnema following Heinicke et al. (2007). The name Ischnocnema henselii is resurrected to accommodate a species that was first detected through differences in advertisement call parameters (Kwet and Solé, 2005).
