We report on the production of ultracold heteronuclear YbLi* molecules in a dual-species magneto-optical trap by photoassociation (PA). The formation of the electronically excited molecules close to dissociation was observed by trap loss spectroscopy. We find 4 rovibrational states within a range of 250 GHz below the Yb(^1S_0) + Li(^2P_1/2) asymptote and observe isotopic PA line shifts in mixtures of ^6Li with ^174Yb, ^172Yb, and ^176Yb. We also describe our theoretical ab-initio calculation
