Two new species of Petrobunus Sharma Giribet, 2011, (Petrobunidae) are described: P. chongqing sp. nov. (♀♂) and P. hebei sp. nov. (♀♂). Petrobunus chongqing sp. nov. is similar to P. spinifer Sharma Giribet, 2011, in having two large spines on the male sternite 7. However, the new species can be distinguished from P. spinifer by the absence of a ventral tubercle on the male femur IV, as well as the presence of three pairs of enlarged tubercles on the lateral margin of area V and free tergites I-II. Petrobunus hebei sp. nov. and P. torosus Sharma Giribet, 2011 closely resemble each other. They are distinguished by the morphology of the ocularium, in that P. torosus has a median tubercle whereas the ocularium of P. hebei sp. nov. is unarmed. The discovery and descriptions of these species greatly expand the known range of the genus Petrobunus.
