We present seven new transiting hot Jupiters from the WASP-South survey .
The planets are all typical hot Jupiters orbiting stars from F4 to K0 with magnitudes of V = 10.3 to 12.5 .
The orbital periods are all in the range 3.9–4.6 d , the planetary masses range from 0.4–2.3 M _ { Jup } and the radii from 1.1–1.4 M _ { Jup } .
In line with known hot Jupiters , the planetary densities range from Jupiter-like to inflated ( \rho = 0.13–1.07 \rho _ { Jup } ) .
We use the increasing numbers of known hot Jupiters to investigate the distribution of their orbital periods and the 3–4-d “ pile-up ” .
