摘要：
The genus Rudisiricius Gao, Rasnitsyn, Shih & Ren, 2010 is emended. Six new species, R ferox sp. nov., R. ater sp. nov., It tenellus sp. nov., R. parvus sp. nov.. R. membranaceous sp. nov. and R. validus sp. nov., are described and illustrated. These well-preserved specimens were all collected from the Jehol Biota, Early Cretaceous, Yixian Formation of Huangbanjigou Village in Liaoning, China. Based on the new morphological data, a key of Rudisiricius is provided. These insects are all males that possess larger body length, stronger mandibles and thicker scapes than other Praesiricidae. These new findings and morphological characters enhance our understanding of the evolution and relationships of the enigmatic family Praesiricidae. (C) 2014 Elsevier Ltd. All rights reserved.
