We report two new dramatically dusty main sequence stars : HD 131488 ( A1 V ) and HD 121191 ( A8 V ) .
HD 131488 is found to have substantial amounts of dust in its terrestrial planet zone ( L _ { IR } /L _ { bol } \approx 4 \times 10 ^ { -3 } ) , cooler dust further out in its planetary system , and an unusual mid-infrared spectral feature .
HD 121191 shows terrestrial planet zone dust ( L _ { IR } /L _ { bol } \approx 2.3 \times 10 ^ { -3 } ) , hints of cooler dust , and shares the unusual mid-infrared spectral shape identified in HD 131488 .
These two stars belong to sub-groups of the Scorpius-Centaurus OB association and have ages of \sim 10 Myr .
HD 131488 and HD 121191 are the dustiest main sequence A-type stars currently known .
Early-type stars that host substantial inner planetary system dust are thus far found only within the age range of 5-20 Myr .
