Question: What is the northern equivalent to the area that the Southern Cone is south of and around?

Context paragraphs:
Demographics of the Southern Cone: The Southern Cone (Spanish: "Cono Sur" , Portuguese: "Cone Sul" ) is a geographic region composed of the southernmost areas of South America, mostly south of the Tropic of Capricorn.  Although geographically this includes part of Southern and Southeastern (São Paulo) Brazil, in terms of political geography the Southern cone has traditionally comprised Argentina, Chile, Paraguay, and Uruguay.  In the narrowest sense, it only covers Argentina, Chile and Uruguay.

Triatoma infestans: Triatoma infestans, commonly called winchuka "(vinchuca)" in Argentina, Bolivia and Chile, barbeiro in Brazil and also known as "kissing bug" or "barber bug" in English, is a blood-sucking bug (like all the members of its subfamily Triatominae) and the most important vector of "Trypanosoma cruzi" which can lead to Chagas disease.  It is widespread in the Southern Cone countries of South America; that is, in Bolivia, Argentina, Uruguay, Paraguay, Chile, Brazil and Peru.  In all these countries "T. infestans" is almost an exclusively domestic species, except in Bolivia where sylvatic forms have been recorded in rock piles in association with wild guinea pigs.  This region has joined the control intervention called "Southern Cone Initiative" managed by the PAHO.

David Leake: David Leake was the Assistant Bishop of Northern Argentina from 1969 to 1989 when he became diocesan Bishop and for the latter part of that Episcopate Primate of the Southern Cone.  Born on 26 June 1935 to missionary parents serving in Argentina, he was ordained in 1959 and began his career with a curacy in Watford.  In 1963 he went to South America where he served the Church as a Missionary eventually rising to the Episcopate.  In retirement he continues to serve the church as an Assistant Bishop in the Diocese of Norwich.  and also serves as a consultant to the Argentine Bible Society specialising in the Toba language translation of the Toba (oeste) New Testament.  On retirement he was honoured by the Queen with the CBE.

Southern Cone: Southern Cone (Spanish: "Cono Sur" , Portuguese: "Cone Sul" ) is a geographic and cultural region composed of the southernmost areas of South America, south of and around the Tropic of Capricorn.  Traditionally, it covers Argentina, Chile and Uruguay, bounded on the west by the Pacific Ocean, and south to the junction between the Pacific and Atlantic Oceans, which is the continental area closest to Antarctica (1000 km).  In terms of social and political geography, the Southern Cone comprises Argentina, Chile, Uruguay, part of Southern and Southeastern (São Paulo) Brazil and sometimes Paraguay.

South America: South America is a continent located in the western hemisphere, mostly in the southern hemisphere, with a relatively small portion in the northern hemisphere.  It may also be considered a subcontinent of the Americas, which is the model used in nations that speak Romance languages.  The reference to South America instead of other regions (like Latin America or the Southern Cone) has increased in the last decades due to changing geopolitical dynamics (in particular, the rise of Brazil).

Bibimys chacoensis: Bibimys chacoensis is a species of small rodent of the family Cricetidae living in the north-central part of Southern Cone of South America.  It is one of the three species currently recognized under the genus "Bibimys".  The common name of this species is Chaco crimson-nosed rat (in Spanish: "ratón de hocico rosado norteño" [Northern pink-nosed mice])

Argentina: Argentina ( ; ] ), officially the Argentine Republic (Spanish: "República Argentina" ), is a federal republic in the southern portion of South America.  Sharing the bulk of the Southern Cone with its neighbor Chile to the west, the country is also bordered by Bolivia and Paraguay to the north, Brazil to the northeast, Uruguay and the South Atlantic Ocean to the east, and the Drake Passage to the south.  With a mainland area of 2780400 km2 , Argentina is the eighth-largest country in the world, the second largest in Latin America, and the largest Spanish-speaking one.  The country is subdivided into twenty-three provinces (Spanish: "provincias" , singular "provincia") and one autonomous city ("ciudad autónoma"), Buenos Aires, which is the federal capital of the nation (Spanish: "Capital Federal" ) as decided by Congress.

Tropic of Capricorn: The Tropic of Capricorn (or the Southern Tropic) is the circle of latitude that contains the subsolar point on the December (or southern) solstice.  It is thus the southernmost latitude where the Sun can be directly overhead.  Its northern equivalent is the Tropic of Cancer.

Xenastrapotherium: Xenastrapotherium is an extinct genus of astrapothere, a type of hoofed herbivorous mammal, native to South America, which lived in the Middle to Late Miocene period, typically during the Laventan stage.  It is a member of the family Astrapotheriidae in the subfamily Uruguaytheriinae, large astrapotheres, equipped with a trunk-like nose and protruding teeth, similar to the elephants, but their tusks were the canine teeth, not the incisors.  "Xenastrapotherium" (named after the Greek word "xenos" "strange" add to the genus "Astrapotherium", "lightning beast") was a genus widely distributed in northern South America, in contrast to other species of astrapotheres which lived in the area of the Southern Cone of the continent.  It differed from other astrapotheres by having two lower incisors on each side of the jaw and the tusks have a pronounced longitudinal curvature, although their general shape and size are probably very similar to "Astrapotherium", whose weight would be 900 to 1,500 kilograms, comparable to the current black rhino.

List of companies of Argentina: Argentina is a federal republic in the southern half of South America.  Sharing the bulk of the Southern Cone with its neighbor Chile to the west, the country is also bordered by Bolivia and Paraguay to the north, Brazil to the northeast, Uruguay and the South Atlantic Ocean to the east, and the Drake Passage to the south.
