摘　　要：Antennal sensilla are investigated in three xylophagous cockroaches： Cryptocercus meridianus, C. habaensis and C. changbaiensis, using scanning electron microscopy （SEM）. General morphology of the antenna is provided in detail, and no significant differences are found among the three species. Six primary types of sensilla are observed and measured： sensilla chaetica （Ch）, sensilla trichodea （Tr）, sensilla basiconica （Ba）, sensilla coeloconica （Co）, sensilla campaniformia （Ca） and sensilla capitula （Cp）. Sensilla trichodea 1 （Trl） is the most abundant sensillum in all three species. There are some statistical differences between sexes and among species. Comparing Cryptocercus with other cockroaches and termites, we briefly discuss the differences among them in terms of their habitat. According to the statistical analysis performed with the sensilla, these morphological characteristics are not enough to separate the three species and may not be suitable for a classification at species level.利用扫描电镜观察了3种食木性蜚蠊:滇南隐尾蠊、哈巴隐尾蠊和长白隐尾蠊的触角感器。在本文中对上述3种隐尾蠊的触角形态进行了详细的描述,3种隐尾蠊触角无明显差异。观察并测量了6种主要的感器类型:刺形感器、毛形感器、锥形感器、腔锥形感器、钟形感器和小头感器。结果发现,在3种隐尾蠊触角上毛形感器是最丰富的感器。统计表明感器在3种隐尾蠊种间和两性间存在一些差异。与其他蜚蠊和白蚁进行了比较,并讨论了它们在生活习性上的差异。综上所述,感器的形态描述和统计分析不足以对3种隐尾蠊进行分类鉴别,不宜作为种级单元分类特征。
