A second species, A. giganteum, was discovered in the Ethiopian highlands of Chilga in 2003.
The earlier survey found that of the land under cultivation in Chilga, 64.53% was planted in cereals like teff, maize and finger millet, 2.81% in pulses like horse beans, 8.3% in oilseeds like neug, 0.72% in perennial crops like coffee, 0.62% in root crops, 0.45% in vegetables, and 12.57% all other crops.
It is known from late Oligocene (27 to 28 million years old) fossil teeth found in the Ethiopian district of Chilga.

At some point following his deposition from the throne in 1606, Emperor Susenyos of Ethiopia appointed him governor of Chilga (also known as Ayikel), an important market town near the Ethiopian border with Sennar.
Ayikel is mentioned, by its older name of "Chilga", by James Bruce, as a marketplace on the border between the Kingdom of Sennar and Ethiopia which was under their shared administration, and over which Emperor Susenyos in 1606 appointed the deposed king of Senaar, Abd al-Qadir as governor.
