Abstract

Adult hangingflies are very sensitive to humidity, thereby frequently being used as ecological indicators to assess the degradation of the environment, especially forest ecosystems. Studies on the sense organs associated with hygro- and thermo-sensitivity, however, have been scant. Here, the ultramorphology and distribution of the flagellar sensilla were investigated in the adult hangingflies Bittacus planus Cheng, 1949 and Bittacus sinicus Issiki, 1931 using scanning electron microscopy. Four types of sensilla are identified in B. planus, including sensilla campaniformia, sensilla chaetica (SC1, SC2), sensilla basiconica (SB1, SB2), and sensilla coeloconica. In B. sinicus, sensilla chaetica III are present additionally from 7th to 14th flagellomeres. Abundant sensilla coeloconica are present on the flagella of Bittacus. Sensilla basiconica I are situated at the joints of flagellomeres. Sensilla campaniformia are densely distributed on the basal half of the first flagellomere, but scarcely on other flagellomeres. Sensilla chaetica II are present on the distal three flagellomeres. The size, abundance, and distribution of flagellar sensilla differ considerably between B. planus and B. sinicus. We infer that the abundance of sensilla coeloconica is likely associated with the hygro- and thermo-sensitivity in Bittacidae. Studies of flagellar sensilla can provide valuable information for subsequent electrophysiological, behavioral, biogeographical, and phylogenetic analyses of Bittacidae.

扁齿齿蛛(Bittacus planus Cheng)和中国齿蛛(Bittacus sinicus Issiki)的鞭毛感觉器(机械翅目:齿蛛科)。
成虫对湿度非常敏感,因此经常被用作评估环境退化,特别是森林生态系统退化的生态指标。然而,对与湿热敏感性相关的感觉器官的研究却很少。本文用扫描电子显微镜研究了成年hangingflies Bittacus planus Cheng(1949)和Bittacus sinicus Issiki(1931)鞭毛感受器的超微结构和分布。在B.planus中鉴定出四种类型的感觉器,包括campaniformia感觉器、chaetica感觉器(SC1,SC2)、basiconica感觉器(SB1,SB2)和co-loconica感觉器。在B.sinicus中,毛感器III另外存在于第7至第14个鞭毛。Bittacus的鞭毛上有丰富的共腔感器。碱性敏感菌I位于鞭毛的结合处。campaniformia感菌密集分布在第一个鞭毛的基部半部分,而在其他鞭毛上几乎没有分布。毛感菌II存在于远端的三个鞭毛上。扁尾蠊和中国尾蠊的鞭毛感器的大小、丰度和分布有很大差异。我们推断,共腔感器的丰度可能与Bittacidae的湿热敏感性有关。鞭毛感受器的研究可以为随后的Bittacidae的电生理、行为、生物地理学和系统发育分析提供有价值的信息。

期刊介绍: Arthropod Structure & Development is a Journal of Arthropod Structural Biology, Development, and Functional Morphology; it considers manuscripts that deal with micro- and neuroanatomy, development, biomechanics, organogenesis in particular under comparative and evolutionary aspects but not merely taxonomic papers. The aim of the journal is to publish papers in the areas of functional and comparative anatomy and development, with an emphasis on the role of cellular organization in organ function. The journal will also publish papers on organogenisis, embryonic and postembryonic development, and organ or tissue regeneration and repair. Manuscripts dealing with comparative and evolutionary aspects of microanatomy and development are encouraged.
