We report the discovery of two transiting extrasolar planets from theHATSouth survey. HATS-11, a V=14.1 G0-star shows a periodic 12.9 mmag dip inits light curve every 3.6192 days and a radial velocity variation consistentwith a Keplerian orbit. HATS-11 has a mass of 1.000 $\pm$ 0.060 M$_{\odot}$, aradius of 1.444 $\pm$ 0.057 M$_{\odot}$ and an effective temperature of 6060$\pm$ 150 K, while its companion is a 0.85 $\pm$ 0.12 M$_J$, 1.510 $\pm$ 0.078R$_J$ planet in a circular orbit. HATS-12 shows a periodic 5.1 mmag fluxdecrease every 3.1428 days and Keplerian RV variations around a V=12.8 F-star.HATS-12 has a mass of 1.489 $\pm$ 0.071 M$_{\odot}$, a radius of 2.21 $\pm$0.21 R$_{\odot}$, and an effective temperature of 6408 $\pm$ 75 K. For HATS-12,our measurements indicate that this is a 2.38 $\pm$ 0.11 M$_J$, 1.35 $\pm$ 0.17R$_J$ planet in a circular orbit. Both host stars show sub-solar metallicity of-0.390 $\pm$ 0.060 dex and -0.100 $\pm$ 0.040 dex, respectively and are(slightly) evolved stars. In fact, HATS-11 is amongst the most metal-poor and,HATS-12 is amongst the most evolved stars hosting a hot Jupiter planet.Importantly, HATS-11 and HATS-12 have been observed in long cadence by Kepleras part of K2 campaign 7 (EPIC216414930 and EPIC218131080 respectively).
