    We report the discovery from WASP-South of a new Jupiter-like extrasolar planet, WASP-16b, which transits its solar analog host star every 3.12 days. Analysis of the transit photometry and radial velocity spectroscopic data leads to a planet with R p = 1.008 0.071 R Jup and M p = 0.855 0.059 M Jup, orbiting a host star with R * = 0.946 0.054 R and M * = 1.022 0.101 M. 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]=0.01 0.10) solar analog (T eff = 5700 150 K and log g = 4.5 0.2) of intermediate age (τ = 2.3+5.8 -2.2 Gyr).
