中文摘要：

广翅目鱼蛉亚科（Chauliodinae）成虫触角形态属间差异显著，其表面感觉器的形态和功能缺乏系统研究。对该亚科4个属的代表种的成虫触角感觉器的超微形态进行观察与比较，发现属模栉鱼蛉触角感器共有5种；西华斑鱼蛉触角感器共有5种；锯角黑鱼蛉触角感器共有4种；全色新鱼蛉触角感受器共有5种。其中，毛形感器Ⅱ型、锥形感器、柱形感器在各种中较为常见，而毛形感器Ⅰ型、毛形感器Ⅳ型、毛形感器Ⅴ型、纽扣形感器及刺形感器仅分别在某一种鱼蛉中特有。研究表明，触角感器在鱼蛉亚科不同属种间无论在类型还是数量分布等方面均存在差异且多样化，同种雌雄两性的触角感器在具有雌雄触角二型性的物种中也具有差异。

英文摘要：

The megalopteran subfamily Chauliodinae （fishflies）has diverse antennal morphologies among genera, but the morphology and function of the antennal sensilla are poorly known.In this study,we described the ultra-morphology of sensilla on the adult antennae of representative species of four fishfly genera.Five types of sensilla were present in Ctenchauliodes nigrovenosus ,Neochauliodes occidentalis and Neohermes concolor .Four types of sensilla were present in Nigronia serricornis .The sensilla trichodea type Ⅱ,the sensilla basiconica and the sensilla cylindric were commonly found in the four fishfly species.However,the sensilla trichodea type Ⅰ,Ⅳ,Ⅴ,the sensilla button-shaped and the sensilla cylindric were only present in one of the fishfly species.It is concluded that the antennal sensilla have different and diverse characteristics among fishfly genera,and the genera with sexual di-morphic antennae also have different characteristics of sensilla between conspecific sexes.
