We report the detection of a 0.6 M_J extrasolar planet by WASP-South, WASP-25b, transiting its solar-type host star every 3.76 d. A simultaneous analysis of the WASP, FTS and Euler photometry and CORALIE spectroscopy yields a planet of R_p= 1.22 R_J and M_p= 0.58 M_Jaround a slightly metal-poor solar-type host star, [Fe/H]=- 0.05±0.10, of R_*= 0.92 R_☉ and M_*= 1.00 M_☉. WASP-25b is found to have a density of ρ_p= 0.32 ρ_J, a low value for a sub-Jupiter mass planet. We investigate the relationship of planetary radius to planetary equilibrium temperature and host star metallicity for transiting exoplanets with a similar mass to WASP-25b, finding that these two parameters explain the radii of most low-mass planets well.
