The external morphology of antenna and fine structure of its sensilla of Maladera orientalis were studied using scanning electron microscopy. The antenna consists of scape, pedicel, funicle and a club composed of three lamellae. Funicle has five, sometimes, four segments. Böhm bristles, three subtypes of sensilla chaetica, one subtype of sensilla trichodea, one subtype of sensilla coeloconica, four subtypes of sensilla basiconica, and one subtype of sensilla placodea were described. No sexual differences were found in number, type and distribution of sensilla on all antennomeres. The most notable feature of sensilla on antennae of M. orientalis is the presence of long and narrow strip-like sensilla placodea on both sides of all club lamellae. These porous sensilla placodea are slightly depressed below the lamella surface and tend to lie in parallel with the lamella axe. They are similar to sensilla placodea found in hymenopteran species but very different from those round plate-like sensilla placodea occurring on the lamellae of scarab beetles.
利用扫描电子显微镜对东方绢金龟触角的外部形态及其感器的精细结构进行了研究。触角由柄节、梗节、鞭节和由三个板片组成的棒节构成。鞭节有五节，有时为四节。描述了博氏鬃毛、三种毛形感器亚型、一种刚毛形感器亚型、一种腔锥形感器亚型、四种锥形感器亚型和一种板形感器亚型。在所有触角节上，感器的数量、类型和分布均未发现性别差异。东方绢金龟触角感器最显著的特征是在所有棒节板片两侧均有狭长的带状板形感器。这些多孔的板形感器在板片表面下方略有凹陷，且倾向于与板片轴平行排列。它们与膜翅目昆虫中发现的板形感器相似，但与金龟子科昆虫板片上的圆形板状板形感器有很大不同。
