Context: A tepui , or tepuy, is a table-top mountain or mesa found in the Guiana Highlands of South America, especially in Venezuela and western Guyana.

It is bordered by Colombia on the west, Brazil on the south, Guyana on the east, and the islands of Trinidad and Tobago to the north-east. Venezuela's territory covers around with an estimated population . Venezuela is considered a state with extremely high biodiversity (currently ranks 7th in the world's list of nations with the most number of species), with habitats ranging from the Andes Mountains in the west to the Amazon Basin rain-forest in the south, via extensive "llanos" plains and Caribbean coast in the center and the Orinoco River Delta in the east., Uruguay, officially the Oriental Republic of Uruguay, is a country in the southeastern region of South America. It borders Argentina to its west and Brazil to its north and east, with the Río de la Plata (River of Silver) to the south and with the Atlantic Ocean to the southeast. Uruguay is home to an estimated 3.42 million people, of whom 1.8 million live in the metropolitan area of its capital and largest city, Montevideo. With an area of approximately , Uruguay is geographically the second-smallest nation in South America, only larger in size than Suriname., The Atlantic Ocean is the second largest of the world's oceans with a total area of about . It covers approximately 20 percent of the Earth's surface and about 29 percent of its water surface area. It separates the "Old World" from the "New World"., A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several such, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN the definitions of types are similar in intent but not identical in terminology or underlying concept., Oreophrynella weiassipuensis is a species of toad in the family Bufonidae. It is only known from Wei-Assipu-tepui, on the border between Brazil and Guyana. The holotype was collected in 2000 by a speleological expedition to Wei-Assipu-tepui. No other specimens are known. It is possible that it is present in other localities, but most species of "Oreophrynella" are endemic to a single mountain., French Guiana (pronounced or ), officially called Guiana, is an overseas department and region of France, located on the north Atlantic coast of South America in the Guyanas. It borders Brazil to the east and south, and Suriname to the west. Its area has a very low population density of only 3 inhabitants per km, with half of its 244,118 inhabitants in 2013 living in the metropolitan area of Cayenne, its capital. By land area, it is the second largest region of France and the largest outermost region within the European Union., Guyana (pronounced or ), officially the Co-operative Republic of Guyana, is a sovereign state on the northern mainland of South America. It is, however, included in the Caribbean Region due to its strong cultural, historical, and political ties with the Caribbean Community (CARICOM). Guyana is bordered by the Atlantic Ocean to the north, Brazil to the south and southwest, Suriname to the east and Venezuela to the west. With , Guyana is the fourth-smallest country on mainland South America after Uruguay, Suriname and French Guiana., The Andes or Andean Mountains are the longest continental mountain range in the world. They are a continuous range of highlands along the western edge of South America. This range is about long, about wide (widest between 18° south and 20° south latitude), and of an average height of about . The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Argentina and Chile., Oreophrynella ( bush toads ) is a genus of true toads native to the tepuis of southern Venezuela and adjacent Guyana . The distribution of some species is restricted to a couple of tepuis or even a single tepui , as in the case of Oreophrynella weiassipuensis , which occurs on Wei - Assipu - tepui ., Brazil, officially the Federative Republic of Brazil, is the largest country in both South America and Latin America. As the world's fifth-largest country by both area and population, it is the largest country to have Portuguese as an official language and the only one in the Americas. Bounded by the Atlantic Ocean on the east, Brazil has a coastline of . It borders all other South American countries except Ecuador and Chile and covers 47.3% of the continent's land area. Its Amazon River basin includes a vast tropical forest, home to diverse wildlife, a variety of ecological systems, and extensive natural resources spanning numerous protected habitats. This unique environmental heritage makes Brazil one of 17 megadiverse countries, and is the subject of significant global interest and debate regarding deforestation and environmental protection., A mountain is a large landform that stretches above the surrounding land in a limited area, usually in the form of a peak. A mountain is generally steeper than a hill. Mountains are formed through tectonic forces or volcanism. These forces can locally raise the surface of the earth. Mountains erode slowly through the action of rivers, weather conditions, and glaciers. A few mountains are isolated summits, but most occur in huge mountain ranges., A habitat is an ecological or environmental area that is inhabited by a particular species of animal, plant, or other type of organism. The term typically refers to the zone in which the organism lives and where it can find food, shelter, protection and mates for reproduction. It is the natural environment in which an organism lives, or the physical environment that surrounds a species population., Mesa (Portuguese and Spanish for "table") is the American English term for tableland, an elevated area of land with a flat top and sides that are usually steep cliffs. It takes its name from its characteristic table-top shape. It may also be called a table hill, table-topped hill or table mountain. It is larger than a butte, which it otherwise resembles closely., The Amazon basin is the part of South America drained by the Amazon River and its tributaries. The Amazon drainage basin covers an area of about , or roughly 40 percent of the South American continent. It is located in the countries of Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Suriname and Venezuela., The Pemon or Pemón (Pemong) are indigenous people living in areas of Venezuela, Brazil, and Guyana. They are also known as Arecuna, Aricuna Jaricuna, Kamarakoto, and Taurepang., Toad is a common name applied to certain frogs, especially of the family Bufonidae, that are characterized by dry, leathery skin, short legs, and parotoid glands., Subject: oreophrynella, Relation: parent_taxon, Options: (A) animal (B) area (C) areas (D) argentina (E) bufonidae (F) delta (G) fungi (H) oreophrynella
