The genus Philoctetes Abeille de Perrin, 1879 from China, with description of two new species (Hymenoptera, Chrysididae)

The Chinese species of the genus Philoctetes Abeille de Perrin, 1879 are revised and keyed for the first time. Six species are recorded, of which two are new for science: Philoctetes longiflagellis Rosa, Wei & Xu, sp. nov. (Inner Mongolia and Shanxi) and P. simulator Rosa, Notton & Xu, sp. nov. (Tianjin). The new synonym, Philoctetes cupratus (Mocsary, 1914), syn. nov. of Philoctetes mongolicus (du Buysson, 1901), is proposed. Philoctetes mongolicus (du Buysson, 1901) is newly recorded from Pakistan.
