[2] The specific name hansenae honours Dora Hansen, friend of Doris Mable Cochran who described this species.
[4][5] Rohanixalus hansenae occurs in association with riparian vegetation around ponds in lowland forest and up to around 1,000 m (3,300 ft) above sea level.
Scientists have observed mother frogs jumping on grasshoppers that presumably wish to eat the eggs.
[5] This species is probably threatened by habitat loss (deforestation) occurring in its distribution area.
It is present in a number of protected areas, for example Khao Kitchakut National Park and Sakaerat Environmental Research Station.
