Abstract
Two new species of the dwarf litter frog genus Leptobrachella are described from North and Central Kalimantan, Indonesian part of the Borneo Island. Leptobrachella fusca n. sp. from Bulungan Regency, differs from all congeneric species in the following combination of characters: body small (SVL: 16.3 mm in a male); dorsum uniformly dark brown; sides of body without marking; a series of elongate ventrolateral glands present on flank; ventrum darkly pigmented except for throat and posterior portion; lineae masculinae invisible through ventral skin in preservative; and toe webs rudimentary. Leptobrachella bondangensis n. sp. from Gunung (=Mt.) Bondang of Murung Raya Regency, is distinct in possessing the following combination of characters: body large as this genus (SVL: 17.8 mm in a male); dorsum grayish brown; sides of body without dark blotches; a sparse series of rounded ventrolateral glands present on flunk; ventrum pale gray with dark mottles; lineae masculinae invisible through ventral skin in preservative; and toe webs rudimentary.
