Antlia is a constellation located in the second quadrant of the Southern Hemisphere and is the representation of an air pump. Originally Antlia Pneumatica, the constellation was listed by Nicolas-Louis de Lacaille in the 18th century. Its name was later abbreviated by John Herschel. Its latitudes are between +45 and -90, while its neighboring constellations are Centaurus, Hydra, Pyxis, and Vela. 

As Antlia was too far south and fainter than most other major constellations, it had never been noticed by the ancient Greeks. It was identified in the 18th century as one of the 14 constellations named by Abbé Nicholas Louis de Lacaille and was listed to fill in empty spaces in the southern hemisphere. For this reason, it has no mythology that is recognizable with other constellations.
