摘要
记述了４种尖天牛和４种坡天牛的雄性外生殖器及雌性生殖器，分析比较了二类天牛在雌雄生殖器结构上的差异，二者区别显著，认为ＢｒｅｕｎｉｎｇＳ将尖天牛属（ＬｙｃｈｒｏｓｉｓＰａｓｃｏｅ）降为一个亚属并入坡天牛属（ＰｔｅｒｏｌｏｐｈｉａＮｅｗｍａｎ）的处理是不恰当的，应恢复其属级地位。最后结合后翅翅脉特点及外部形态特征对尖天牛属的属征进行了重新描述。
Male genitalia and female reproductive organs of 4 species in Lychrosis and 4 species in Pterolophia were described. Difference between Lychrosis and Pterolophia were compared by the structure of two sexal organs. It's necessary to reinstate the generic status of Lychrosis which was degraded to a subgenus of genus Pterolophia by Breuning in 1965. A redescription of the genus Lychrosis was given based on the characteristics of hind wing and external morphology and male/female sexal organs was discussed comprehensively.
