The small Antlia cluster of galaxies was investigated by measuring many radial velocities for galaxies from the Lauberts catalog in the Antlia region. Apart from the Antlia cluster itself, four more small groups were identified. These five systems form a tiny but not bound Antlia mini-supercluster. The mini-supercluster consists of small groups and clusters and of a dispersed component of field galaxies. The five galaxy systems are also part of the large Hydra I-Centaurus supercluster. This large supercluster belongs now to the class of well observed ones. It has a chain-like filamentary structure. This supercluster seems to be connected to the Local Supercluster via two very extended but very loose groups. The total structure is the triangle-shaped Virgo-Hydra I-Centaurus supercluster.
