It is endemic to the state of Rio de Janeiro, Brazil, and is only known from the Serra dos Órgãos ("Organ Mountains").[1][3] Common name Organ Mountains robber frog has been coined for this species.[3] EtymologyThe specific name gualteri honors Gualter Adolpho Lutz,[2] brother of Bertha Lutz who described the species. Lutz thanks him for collecting many of the specimens as well as color photographs.[2] DescriptionAdult males measure {{convert|40|-|44|mm|abbr=on}} and females {{convert|44|-|51|mm|abbr=on}} in snout–vent length. It is a robustly built frog with massive head, as wide as long. The tympanum is partly visible. The hind limbs are long. The digits are narrow and fringed, with the outer ones ending with a large disc. Toes have rudiments of webbing. Skin is mostly smooth but there are a few warts, particularly on the head and the upper eyelids. Dorsal coloration is brown with variable patterning. The iris is strikingly copper colored.[2] Habitat and conservationIts natural habitats are primary and good quality rainforests[1] at elevations of {{convert|800|–|1200|m|abbr=on}} above sea level. It lives on the forest floor.[1][2] There are no threats to this species at present.[1] It occurs in the Serra dos Órgãos National Park.[2] {{Location map | Brazil| relief = yes | float = right | caption = Ischnocnema gualteri is only known from the Serra dos Órgãos range in Brazil | alt = Serra dos Órgãos in Brazil | lat_deg = -22.44 | lon_deg = -42.98 }} References1. ^1 2 3 4 {{cite journal | author = Potsch de Carvalho-e-Silva, S. | author2 = Telles, A.M. | author3 = Gonçalves da Cruz, C.A. | title = Ischnocnema gualteri | journal = IUCN Red List of Threatened Species | volume= 2004 | page = e.T56635A11511212 | year = 2004 | doi = 10.2305/IUCN.UK.2004.RLTS.T56635A11511212.en }} [2][3]2. ^1 2 3 {{cite web |url=http://research.amnh.org/vz/herpetology/amphibia/Amphibia/Anura/Brachycephaloidea/Brachycephalidae/Ischnocnema/Ischnocnema-gualteri |title=Ischnocnema gualteri (Lutz, 1974) |author=Frost, Darrel R. |year=2017 |work=Amphibian Species of the World: an Online Reference.
