Two new species of Dolichurus Latreille (Hymenoptera, Ampulicidae) from China, with a key to species of the genus

Two new species of Dolichurus Latreille, 1809, namely D. albipedigerus Bai & Li, sp. nov. and D. nigrilamellatus Bai & Li, sp. nov. are described from China (Yunnan, Guangdong and Jiangxi Provinces). Dolichurus albipedigerus Bai & Li, sp. nov. is similar to D. apiciornatus Tsuneki, 1977, but differs in having the mandible ivory white medially, the clypeus with a weak median carina, and the body with ivory-white spots. Dolichurus nigrilamellatus Bai & Li, sp. nov. is similar to D. aposanus Tsuneki et al., 1992, but differs in having the frons with dense rugae converging toward the midline above the lamella, the sternaulus conspicuous, and the posterior margin of T 1 - T 3 without tiny puncture-rows medially.

Additionally, a key to the Chinese species of Dolichurus is provided.
