拟步甲（学名：Eleodes longicollis）的后腹部有一对腺体，可以产生醌类、碳氢化合物、辛酸和葡萄糖的混合物。腺体的开口靠近肛门旁边的腹部尖端，当动物受到干扰时，分泌物被排出，是防御捕食者的有效手段。每个腺体由囊状贮液器和相关的分泌细胞复合体组成。贮器实质上是体壁的内折，由膜状表皮衬里和单层上皮组成。分泌细胞，这是安排为两个不同的群体，详细描述的基础上，光，相，和electronmicroscopy。它们的主要特征是拥有单个大囊泡，由管状表皮细胞器引流，导致水库。提出了一个假设，旨在解释，根据已知的腺细胞结构的改进，这些细胞如何产生毒素而不毒害自己。
The tenebrionid beetle, Eleodes longicollis, has a pair of glands in its posterior abdomen which produce a mixture of quinones, hydrocarbons, caprylic acid, and glucose. The openings of the glands are near the abdominal tip beside the anus, and the secretion, which is discharged when the animal is disturbed, is an effective means of defense against predators. Each gland is composed of a sac-like reservoir, and an associated complex of secretory cells. The reservoir is essentially an infolding of the body wall, and consists of a membranous cuticular lining, accompanied by a simple epithelium. The secretory cells, which are arranged as two distinct populations, are described in detail on the basis of light-, phase-, and electronmicroscopy. Their principal characteristic is the possession of single large vesicles, drained by tubular cuticular organelles that lead to the reservoir. A hypothesis is presented, designed to explain, in the light of the known structural refinements of the gland cells, how these cells produce poisons without poisoning themselves.
