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.展开更多
