摘　　要：对采自新疆伊犁河谷西天山野果林的金小蜂科一中国新纪录属爪突金小蜂属(Micradelus Walker,1834)和一新纪录种尖腹爪突金小蜂(Micradelus acutus Graham,1969)进行详细的外部形态特征描述,编制该属世界已知种的检索表,并提供该种的成虫形态特征图以及ITS2和28S rDNA序列信息;结合形态学和分子分析结果,认为将爪突金小蜂属归入寡节金小蜂亚科更合适。所有研究标本均保存在新疆大学生命科学与技术学院昆虫标本馆(ICXU)。A new Chinese record genus Micradelus Walker and a new record species Micradelus acutus Graham,from the wild fruit forests of the Western Tianshan Mountains in the Ili river valley of Xinjiang,was described in detail.A key to known species of the genus in the world was profiled,the detailed adult morphological characteristics photos,its ITS2 and 28S rDNA sequences were also provided.The results of morphological and molecular analysis suggest that it’s more appropriate to classify the genus Micradelus into the subfamily Pireninae.The specimens were deposited in the Insect Collection at College of Life Sciences and Technology of Xinjiang University(ICXU).
