Abstract: The two-dimensional transition metal dichalcogenide ${\mathrm{PdTe}}_{2}$ has recently attracted much attention due to its phase coexistence of a type-II Dirac semimetal and type-I superconductivity. Here we report a 67% enhancement of the superconducting transition temperature in 1T-PdSeTe in comparison to that of ${\mathrm{PdTe}}_{2}$ through partial substitution of Te atoms by Se. The superconductivity has been unambiguously confirmed by the magnetization, resistivity, and specific heat measurements. 1T-PdSeTe shows type-II superconductivity with large anisotropy and a nonbulk superconductivity nature with a volume fraction of $\ensuremath{\approx}20%$ estimated from magnetic and heat capacity measurements. 1T-PdSeTe expands the family of superconducting transition metal dichalcogenides and thus provides additional insights for understanding superconductivity and topological physics in the 1T-${\mathrm{PdTe}}_{2}$ system
