also in the western part but a bit further north than the type locality, along the road between Morafenobe and Beravina village at an altitude of 290 m. This locality consisted of dry savannah with mixed wood and grassland ecosystem after deforestation. The habitat consisted of muddy/sandy residual pools with some dead leaves in a temporary stream after the rainy season. The dry deciduous forest ecosystem in western Madagascar has suffered immensely from deforestation and very little of this habitat remains (

). The species is rare and likely threatened due to the disappearance of western deciduous forests in Madagascar. That all four known specimens are females may suggest an uneven sex ratio as a test of equal sex ratio is marginally non-significant (p = 0.0625) if considered randomly picked from the population.
