The antennae and their sense organs in nymphs and adult roaches of Gromphadorhina brunneri, were investigated and described. The number of segments and sensillae of the nymphal antennae depend on the developmental stage. Sexual dimorphism is pronounced. Males have longer antennae than females as well as an abundance of especially long sensory hairs (long wavy hairs), which are probably responsible for the perception of female sex pheromones. They also have more thin-walled sensory hairs, for instance, sensilla trichodea. On a morphological basis the sensillae of Gromphadorhina brunneri, were named and classified. Long wavy hairs and large sensory hairs appear to be present also in a related species, G. portentosa, but are lacking in others. Their distribution on the antennae varies greatly from that in G. portentosa but their structure varies only slightly. These two types of sense organs are considered to be specialized forms of sensilla chaetica. They are contact chemoreceptors, as are two other types of sensilla chaetica. Furthermore, thin-walled chemoreceptors are present, such as sensilla trichodea, sensilla basiconica, sensilla coeloconica and a typical mechanoreceptor, the sensillum campaniformium.
对布氏巨人蟑螂若虫和成虫的触角及其感觉器官进行了研究和描述。若虫触角的节数和感器数量取决于发育阶段。两性异形明显。雄性的触角比雌性长,并且有大量特别长的感觉毛(长波浪状毛),这些毛可能负责感知雌性性信息素。它们还有更多薄壁感觉毛,例如毛形感器。基于形态学对布氏巨人蟑螂的感器进行了命名和分类。长波浪状毛和大型感觉毛在相关物种——马岛发声蟑螂中似乎也存在,但在其他物种中则没有。它们在触角上的分布与马岛发声蟑螂有很大差异,但其结构仅略有不同。这两种感觉器官被认为是毛形感器的特化形式。它们是接触化学感受器,另外两种毛形感器也是如此。此外,还存在薄壁化学感受器,如毛形感器、锥形感器、腔锥形感器以及一种典型的机械感受器——钟形感器。
