摘要昆虫触角是昆虫重要的感觉器官，内有大量的感受器和受体，用于感知支配其世界的各种各样的线索。历史上，不一致的术语和标准已被用于分类触角感器，这极大地阻碍了数据的比较，即使在密切相关的物种。长角甲虫（鞘翅目：天牛科（Cerambycidae）也不例外，尽管它们有突出的触角，但很少有研究调查它们的触角形态和超微结构，也没有比较天牛科之间感觉器的多样性和变化。目前对天牛触角感器的研究仅包括8个天牛亚科中的5个亚科的29个种，并且包括错误鉴定的感器类型和相互冲突的术语。因此，对天牛触角感器进行形态学比较研究是非常困难的，并且很难理解天牛感觉系统的种间和种内差异。为了便于将来的比较研究，我们回顾了所有可用的已发表的使用扫描和透射电子显微镜的论文利用扫描电镜和透射电镜对天牛触角感器进行了研究，并首次尝试对天牛触角感器类型和亚型进行标准化分类。具体来说，我们讨论了七种主要类型的触角感器（布姆刚毛，感器chaetica，化学感受毛，感器basiconica，圆顶形器官，感器coeloconica，和感器auricillica）。我们还成像触角的相关物种的长角甲虫使用扫描电镜，并包括图像例示尽可能多的感器类型和亚型。
Abstract Insect antennae are crucial sensory organs that house numerous sensilla with receptors for perceiving a wide variety of cues dominating their world. Historically, inconsistent terminology and criteria have been used to classify antennal sensilla, which has greatly impeded the comparison of data even across closely related species. Longhorn beetles (Coleoptera: Cerambycidae) are no exception to this quandary, and despite their prominent antennae, few studies have investigated their antennal morphology and ultrastructure, and none have compared sensillar diversity and variation among cerambycids. Existing studies of longhorn beetle antennal sensilla include only 29 species in five of the eight cerambycid subfamilies and include misidentified sensilla types and conflicting terminology. As such, it is very difficult to conduct comparative morphological studies of antennal sensilla in longhorn beetles and challenging to understand inter- and intra-specific variation in the sensory systems of these beetles.To facilitate future comparative studies, we reviewed all accessible published papers that have used scanning and transmission electron microscopy (SEM and TEM) to investigate antennal sensilla in cerambycids, and present a first attempt at standardizing the classification of their documented sensilla types and subtypes. Specifically, we discuss seven major types of antennal sensilla (Boöhm bristles, sensilla chaetica, chemosensory hairs, sensilla basiconica, dome shaped organs, sensilla coeloconica, and sensilla auricillica). We also imaged the antennae of relevant species of longhorn beetles using SEM and included images exemplifying as many of the sensilla types and subtypes as possible.
