Notice the Mounted Grenadier.
Grenadiers were heavy infantry of the line, hence why the soldier here is armed like a heavy dragoon, with a pallask, a straight single-edged sword.
The uniform is post-Napoleonic.
The colorful uniforms stayed on during the "long peace" in Europe from 1815 to the 1850's, where the technical development of the rifle combined with the need for being practical finally saw the end of such uniforms we see here.
The European style of uniforms inspired other countries outside Europe, also in South America - even though the period mentioned above period was anything but peaceful in South America! That was the period of the revolutions were several countries gained independence.
Anyway, Argentina is well suited for cavalry warfare, hence the reason why elite infantry regiments became mounted. Grenadiers were elite infantry, so when placed on a horse the uniform was "simplified" a little, riding boots were added, as well as a sword, and voila, you have a mounted grenadier.
Notice that the riding boots go to just below the knee. Often heavy dragoons would wear their boots higher, because they rode in close formation, knee locked behind the knee of the men beside them.
But large scale battles were rare in South America, so the more practical shorter boots were used. Mounted grenadiers either rode up to the battle line, then dismounted and fought with rifles, or remained mounted and steamrolled the opposition in front of them. The opposition, often consisting of militia or peasant conscripts who were poorly trained and even worse disciplined in the face of regular units, was such that it wasn't necessary to ride in close formation in order to ride them down and scatter them.
