Narrative:

After pushing from gate in aus; ground control issued taxi instructions to runway 17R via C2 to C. Our jepps airport info page does not depict a C2 taxiway. We referenced the airport information page which shows taxiway C2 near the intersection of the ramp and G1. We turned left toward C2 and then asked ground control if they wanted us to use G1 from C2; because our page also did not show C2 leading to C. The ground controller asked why we had turned toward the east. We were then instructed to turn back to the west on the ramp and follow aircraft Y. We informed ground control that our taxi diagram does not show a taxiway C2. We were informed that this has been reported previously by other crews. While following aircraft Y; we were able to locate the taxiway C2 yellow line painted on the ground. There is also a taxiway C1 painted on the ground that is not depicted on our jepps page. We should have requested additional instruction from ground control prior to turning out from the gate. The jepps page should be updated to show taxi lanes C1 and C2.
