We report the discovery and characterization of the transiting extrasolarplanet TOI-1710$\:$b. It was first identified as a promising candidate by theTransiting Exoplanet Survey Satellite (TESS). Its planetary nature was thenestablished with SOPHIE and HARPS-N spectroscopic observations via theradial-velocity method. The stellar parameters for the host star are derivedfrom the spectra and a joint Markov chain Monte-Carlo (MCMC) adjustment of thespectral energy distribution and evolutionary tracks of TOI-1710. A joint MCMCanalysis of the TESS light curve and the radial-velocity evolution allows us todetermine the planetary system properties. From our analysis, TOI-1710$\:$b isfound to be a massive warm super-Neptune ($M_{\rm p}=28.3\:\pm\:4.7\:{\rmM}_{\rm Earth}$ and $R_{\rm p}=5.34\:\pm\:0.11\:{\rm R}_{\rm Earth}$) orbitinga G5V dwarf star ($T_{\rm eff}=5665\pm~55\mathrm{K}$) on a nearly circular24.3-day orbit ($e=0.16\:\pm\:0.08$). The orbital period of this planet isclose to the estimated rotation period of its host star $P_{\rmrot}=22.5\pm2.0~\mathrm{days}$ and it has a low Keplerian semi-amplitude$K=6.4\pm1.0~\mathrm{m\:s^{-1}}$; we thus performed additional analyses to showthe robustness of the retrieved planetary parameters. With a low bulk densityof $1.03\pm0.23~\mathrm{g\:cm^{-3}}$ and orbiting a bright host star ($J=8.3$,$V=9.6$), TOI-1710$\:$b is one of the best targets in this mass-radius range(near the Neptunian desert) for atmospheric characterization via transmissionspectroscopy, a key measurement in constraining planet formation andevolutionary models of sub-Jovian planets.
