Using 383 million BBbar pairs from the BaBar data sample, we report results for branching fractions of six charged B-meson decay modes, where a charged kaon recoils against a charmless resonance decaying to KKbar* or etapipi final states with mass in the range (1.2-1.8)gev/c^2. We observe a significant enhancement at the low KK*bar invariant mass which is interpreted as B+ --> eta(1475)K+, find evidence for the decay B+ --> eta(1295)K+, and place upper limits on the decays B+ --> eta(1405)K+,
