  We report the discovery of five new transiting hot Jupiter planets discovered
by the HATSouth survey: HATS-31b through HATS-35b. These planets orbit
moderately bright stars with V magnitudes within the range 11.9-14.4mag while
the planets span a range of masses 0.88-1.22MJ, and have somewhat inflated
radii between 1.23-1.64RJ.These planets can be classified as typical hot
Jupiters, with HATS-31b and HATS-35b being moderately inflated gas giant
planets with radii of $1.64 \pm 0.22$ RJ and 1.464+0.069-0.044RJ, respectively,
that can be used to constrain inflation mechanisms. All five systems present a
higher Bayesian evidence for a fixed circular orbit model than for an eccentric
orbit. The orbital periods range from $1.8209993 \pm 0.0000016$ day for
HATS-35b) to $3.377960 \pm 0.000012$ day for HATS-31b. Additionally, HATS-35b
orbits a relatively young F star with an age of $2.13 \pm 0.51$ Gyr. We discuss
the analysis to derive the properties of these systems and compare them in the
context of the sample of well characterized transiting hot Jupiters known to
date.
