| Comment | |
| Etymology | According to Inca mythology, Uku Pacha represents the underworld, containing the dead and everything that was under terrestrial or aquatic surface. The general legend considers the fountains, caves, volcanoes, and any opening in the Earth's crust as a means of communication between Uku Pacha and Kay Pacha. The word Pacha in Quechua Indian language means “time and space”, but into a more general sense means “Earth”. Thus, the specific epithet allows inference to this semi-fossorial lifestyle. |
