The processes \(e^+e^-\to D_s^+ D_{s1}(2460)^- +c.c.\) and \(e^+e^-\to D_s^{\ast +} D_{s1}(2460)^- +c.c.\) are studied for the first time using data samples collected with the BESIII detector at the BEPCII collider. The Born cross sections of \(e^+e^-\to D_s^+ D_{s1}(2460)^- +c.c.\) at nine center-of-mass energies between 4.467\,GeV and 4.600\,GeV and those of \(e^+e^-\to D_s^{\ast +} D_{s1}(2460)^- +c.c.\) at \({\sqrt s}=\) 4.590\,GeV and 4.600\,GeV are measured. No obvious charmonium or charmonium-like structure is seen in the measured cross sections.
