The Antlia galaxy cluster is the third nearest galaxy cluster after Virgo andFornax. We used the wide-field MOSAIC camera of the 4-m CTIO telescope tosearch in the brightest cluster galaxies for globular cluster systems, whichwere detected in the two larger ellipticals -- NGC 3258 and NGC 3268. Thesegalaxies each contain several thousand clusters; NGC 3258 more than NGC 3268.The color distributions of the globular cluster systems are clearly bimodal.The peak colors agree with those of other ellipticals. The radial numberdensity profiles of the globular cluster systems are indistinguishable for thetwo galaxies and no difference in the distribution of red and blue clusters -as observed in other elliptical galaxies - can be seen. The light profile ofNGC 3268 appears to be similar to that of NGC 1399, the central galaxy of theFornax cluster. NGC 3258 has a light profile which is steeper at large radii.Both galaxies exhibit color gradients, becoming bluer outwards.In NGC 3268, thecolor and morphology in the inner 3" indicate the presence of an inner dustydisk. The globular cluster systems closely trace the galaxy light in thestudied radial regime. The elongation of the cluster systems of both galaxiesis approximately aligned at large radii with the connecting axis of the twogalaxies.We find specific frequencies within a radial range of 4'ofS_N=3.0+-2.0 for NGC 3268 and S_N=6.0+-2.5 for NGC 3258.  As a byproduct resulting from surveying our wide-field frames, we describe astrange absorption feature in the Antlia spiral galaxy NGC 3269, which we arguemight be a tiny galactic dust cloud projected onto NGC 3269.Comment: 12 pages, accepted for publication in the A&
