利用线粒体（COI和ND2）及核（28S）基因的DNA序列，重建了东亚27种茎果蝇属类群的系统发育关系。结果支持了该属类群目前的属/亚属分类，唯准茎果蝇属以及茎果蝇属中亚属尖额果蝇属的并系性除外。对该属类群的祖先分布区和分歧时间进行了重建/估算，并据此探讨了这一重要分支的生物地理历史。研究提出，壳斗科植物，尤其是栎属植物的演化，可能在促进茎果蝇属类群的多样化方面发挥了一定作用。（C）2012爱思唯尔公司版权所有。
The phylogenetic relationship among 27 East Asian species of the Stegana genus group was reconstructed using DNA sequences of mitochondrial (COI and ND2) and nuclear (28S) genes. The results lent support to the current generic/subgeneric taxonomic classification in the genus group with the exceptions of the paraphyly of the genus Parastegana and the subgenus Oxyphortica in the genus Stegana. The ancestral areas and divergence times in the genus group were reconstructed/estimated, and accordingly, the biogeographical history of this important clade was discussed. It was proposed that, the evolution of the plant family Fagaceae, especially Quercus, may have played a certain role in facilitating the diversification of the Stegana genus group.
