I grouped the layers in ArcGIS Desktop and published them to my Portal for ArcGIS, but when I tried to create the Map Application, I see the individual layers. They are not in a group.

If Mosaic isn't what you need then take a look at
Working with group layers: http://resources.arcgis.com/en/help/main/10.2/index.html#//00s500000011000000
within Arc.
You can do it in three steps: Get group names, create groups, and move layers.
For testing purposes, I've replicated your sample scenario:
Run the following code snippet in your QGIS Python console:
# 1. Get group names and list of layer ids
root = QgsProject.instance().layerTreeRoot()
dictGroups={}
for layer in root.findLayers():
if QgsLayerTree.isLayer(layer):
prefix="Site "+layer.layerName().split("_")[0] # Adjust this to fit your needs
if not prefix in dictGroups:
dictGroups[prefix]=[]
dictGroups[prefix].append(layer.layerId())
# 2. Create groups
for key in dictGroups:
root.addGroup(key)
# 3. Move layers
for key in dictGroups:
parent = root.findGroup(key)
for id in dictGroups[key]:
layer = root.findLayer(id)
clone = layer.clone()
parent.insertChildNode(0, clone)
root.removeChildNode(layer)
You should get something like this:

Portal does not support grouped layers. You can only have grouped layers if you share as a web service and include the service in your web map.
