We present results of a search for UCDs in the Antlia Cluster. The selection is based on colors and magnitudes of point 
sources, in the Washington photometric system. The analysis of their color and spatial projected distributions points to a 
relation between colors, luminosities and projected distance to the dominant galaxies.  
Some candidates are confirmed as members through radial velocities from GEMINI-GMOS spectra. Colors and magnitudes of 
these Antlia members are compared to those of UCDs in the Fornax cluster.
