Dang et Yang, 1989 (Hymenoptera: Braconidae) is a biocontrol agent of several scolytid pine pests in Southwest China. We examined the fine morphology of the antennae of adult , as well as the type, shape, and distribution of antennal sensilla, via scanning electron microscopy. The antennae of female and male are filiform and comprise a scape, pedicel, and 31-36 flagellomeres. We detected sexual dimorphism in antennal flagellar length but not in the length of other subsegments. A total of nine morphological types of antennal sensilla varying in cuticular pore structure are present in both sexes, including nonporous types (sensilla trichodea, sensilla chaetica (2 subtypes), and sensilla coeloconica); apical pore types (sensilla basiconica and sensilla auricillica); and multiporous types (dome-shaped sensilla and sensilla placodea (2 subtypes)). Dome-shaped sensilla and sensilla auricillica are reported for the first time for , and their shape differs from that of sensilla in other parasitic wasps. The functional morphology of the sensilla of was compared with that of the sensilla of other parasitic wasps, including those that parasitize concealed insects. This information provides a foundation for further research on the chemical communication and behavior of .
党和杨，1989年（膜翅目：茧蜂科）是中国西南部几种松树小蠹虫的生物防治剂。我们通过扫描电子显微镜检查了成虫触角的精细形态，以及触角感器的类型、形状和分布。雌虫和雄虫的触角呈丝状，由柄节、梗节和31 - 36个鞭节组成。我们检测到触角鞭节长度存在性二态性，但其他亚节的长度不存在性二态性。两性共存在9种形态类型的触角感器，其表皮孔结构各不相同，包括无孔类型（毛形感器、刺形感器（2个亚型）和腔锥形感器）；顶端有孔类型（基部锥形感器和耳形感器）；以及多孔类型（圆顶形感器和板形感器（2个亚型））。圆顶形感器和耳形感器首次在该物种中被报道，其形状与其他寄生蜂的感器形状不同。将该物种感器的功能形态与其他寄生蜂的感器进行了比较，包括那些寄生于隐蔽昆虫的寄生蜂。这些信息为进一步研究该物种的化学通讯和行为奠定了基础。
