Haller's organ consists of the capsule, in which are arranged 7 thin-walled porous olfactory hairs, and an anterior group of sensillae situated in the cuticular recess before the capsule. The anterior group is represented by one thick-walled porous, one conical, two thin and two grooved hairs. The porous hairs are characterized by "plugs", the grooved ones--by a complex system of cavities and tubules. Before the organ there are hairs resembling tactile and gustatory receptors of arthropods, behind the organ there arrange hairs with a system of cavities and tubules. Sensible elements of all sensillae studied are bipolar receptor cells bearing one modified cilium on the surface of peripheral processes. The details of the structure of perceptive and accessory apparatus of the above receptors were investigated.
哈勒氏器由一个囊组成，囊内排列着7根薄壁多孔的嗅觉毛，以及位于囊前方角质凹陷处的一组前感器。前感器组由一根厚壁多孔毛、一根锥形毛、两根细毛和两根有槽毛组成。多孔毛的特征是有“塞子”，有槽毛则有一个复杂的腔和小管系统。在该器官前方有类似节肢动物触觉和味觉感受器的毛，在器官后方则排列着有腔和小管系统的毛。所研究的所有感器的敏感元件都是双极受体细胞，在外周突表面带有一根经过修饰的纤毛。对上述受体的感知和辅助装置的结构细节进行了研究。
