Description

''Leptomantis harrissoni'' can reach a length of about in males, of about in females. These medium-sized frogs have an angular and pointed snout and well developed dark hand webbing. They are basically brown. Tadpoles can reach a length of about , They have a well developed and rather pointed tail fin, an ovoid body and a short snout. The basic color is dark brown.

Biology

''Leptomantis harrissoni'' spends most of its life high up in the forest. Males call for breeding in water-containing holes located in the trunks of trees. Eggs are laid in a foam nest attached to the bark above said tree holes. These frogs use the skin membranes between their fingers as a kind of parachute to make real flights among the branches of trees of the forest (hence the common name of the species).
