摘要
天牛类的幼虫特征，已成为天牛总科探讨演化和分类系统的重要手段，狭胸天牛类由于长期以来未找到幼虫，其地位不能确定，影响到整个天牛科和天牛总科的演化和分类系统的研究存在一个缺口。近年在中国广西和西藏发现了松狭胸天牛ＰｈｉｌｕｓａｎｔｅｎｎａｔｕｓＧｙｌｌｅｎｈａｌ和细点音天牛ＨｅｔｅｒｏｐｈｉｌｕｓｐｕｎｃｔｕｌａｔｕｓＣｈｉａｎｇｅｔＣｈｅｎ的幼虫，前者王缉健（１９８９）和尹新明（１９９４）曾有简短报道。本文对这两种幼虫的形态作了详细描述，以供与近缘类群作比较研究。
The larval stage of philines longicorn beetles has been searched for long time in order to fill the gap in phylogenetic study of Cerambycoidea. In recent years, two species of philine larvae have been found in China, one of them, the Philus antennatus (Gyllenhal), has been briefly reported by Wang (1989) and Yin (1994) from Guangxi, the another collected by Prof. Deng, Dr. Chen and Mr. Zhang from Xizang is a new species. In this paper detailed descriptions of larva of these two species are presented.
