Leptobrachella itiokai 
Eto, Matsui & Nishikawa, 2016

 A new highland species of the dwarf litter frog, Leptobrachella itiokai, is described from Gunung Mulu National Park, northern Sarawak, East Malaysia. It occurs syntopically with another highland species, L. brevicrus, but differs from it by a unique call that may be described as a chirp, with dominant frequency of ca. 10 kHz. The new species is morphologically distinguishable from congeners by the combination of the following traits: rounded ventrolateral glands usually not in series; side of body with small black spots; ventrum entirely dark-coloured with tiny light spots; male with thread-like lineae masculinae.

Key words: Leptobrachella, MtDNA; Phylogeny; Taxonomy; Borneo
