摘要
描述了暗翅筒天牛的形态特征及雌雄外生殖器特征。成虫取食桑叶叶脉，产卵时咬食危害枝条端部，幼虫蛀食枝条。亦危害构树、黄桷树、无花果、野梨、苎麻、长叶水麻。暗翅筒天牛危害桑树造成严重的产叶量损失，其被害枝产叶量损失率达41.75％。
The article account the morphological characters and the female and male exterior genitalia characters of Oberea fuscipennis. The imagos of Oberea fuscipennis eat veins of mulberry leaves. When laying eggs, they bite the top part of shoot. The larvae bore and eat the boughs of mulberry trees. Oberea fuscipennis also endanger other plants, such as Broussonetia popyrifera L.
