We report the discovery from WASP-South of a new Jupiter-like extrasolar planet, WASP-16b, which transits its solar analogy host star every 3.12 days. Analysis of the transit photometry and radial velocity spectroscopic data leads to a planet with R_p = 1.0080.071 R_Jup and M_p =0.8550.059 M_Jup, orbiting a host star with R_* = 0.9460.054 R_sun and M_* = 1.0220.101 M_sun. Comparison of the high resolution stellar spectrum with synthetic spectra and stellar evolution models indicates the host star is a near-solar metallicity ([Fe/H]= 0.010.10) solar analogy (Teff = 5700150 K, log g= 4.50.2) of intermediate age (Tau = 2.3+5.8-2.2 Gyr).
