There are more than one major lines of longitude that pass through the Argentine. They have values around 58 degrees west but none of the lines/meridians is a named line.
another name for a line of longitude is meridian.
A "meridian" is a line of constant longitude.
Lines of longitude are also called meridians.
latitude lines is another name for parallels and longitude lines are called meridians
Every 'line' of constant longitude is a 'meridian'.

Lines of longitudes are also called Meridians. These vertical lines are drawn from the North to South poles.The meridian through Greenwich, England, called the Prime Meridian, was set at zero degrees of longitude. The meridian on the opposite side of the earth from Greenwich is called the International Date Line (IDL), which is at roughly 180° longitude.
All of the longitude "lines" merge at the north and south poles, so you might say that they 'start' at one of these points and end at the other one. If the question means to ask: "Where is the line of zero longitude ?", then the answer is: The origin of longitude is defined as the Prime Meridian, an imaginary line between the north and south poles that passes through the Royal Observatory in Greenwich, England.
