We have obtained deep photometry of NGC 1199 (in HCG 22) and NGC 6868 (in the Telescopium group). Both galaxies are the optically brightest galaxies of their groups. Our analysis of B and R images taken with the Keck II and the VLT/ESO telescopes, detected a population of globular clusters around both galaxies, with total specific frequencies SN = 1.7 ± 0.6 for NGC 1199 and SN = 1.3 ± 0.6 for NGC 6868. The color distributions of the globular cluster systems shows bimodal peaks centered at (B - R)0 = 1.13 ± 0.10 and 1.42 ± 0.10 (NGC 1199) and (B - R)0 = 1.12 ± 0.10 and 1.42 ± 0.10 (NGC 6868).
