I think you mean a zoom macro, not a telephoto macro, so here goes:
Canon doesn't have a macro zoom at all, and for that matter neither does Pentax or Sony, but Nikon did, the 70-180, which was discontinued almost a decade ago. A quick search turns up zero current zoom macro/micro lenses at either B&H or Adorama for any DSLR.
If the reproduction ratios of the 24-70 are good enough for you, then that should be fine.
If you do mean telephoto macro, both the 200 and 105 mm Micro lenses both very capable.
