A new gall wasp species, Dryocosmus liui Pang, Su et Zhu n. sp., is described from Hunan Province, China. The new species forms integral galls on branches of Castanopsis tibetana Hance. The results of morphological comparison, pair-wise genetic distance of mtDNA COI, and phylogenetic analysis based on COI gene sequences did not support treating Chilaspis and Dryocosmus as separate genera. Our results also provided new evidence supporting the notion that the Nearctic Dryocosmus species may represent a lineage distinct from the Old World species of the genus.
中国湖南省发现一种新的瘿蜂物种——刘氏栎瘿蜂Dryocosmus liui Pang, Su et Zhu n. sp.。该新物种在西藏锥栗(Castanopsis tibetana Hance)的树枝上形成完整的虫瘿。形态比较、线粒体DNA COI的两两遗传距离以及基于COI基因序列的系统发育分析结果均不支持将Chilaspis属和Dryocosmus属分开处理。我们的研究结果还提供了新的证据,支持近北区Dryocosmus物种可能代表一个与该属旧世界物种不同的谱系这一观点。
