Sperm structure of seven species from different Carabidae tribes was studied. Carabus preslii and Carabus granulatus interstitialis form sperm bundles (spermatozeugmata) in which the heads of conventional insect sperm cells are embedded in the apical cap (spermatostyle), leaving the posterior flagella free. On the contrary, Pterostichus morio, Pterostichus melas, Pterostichus melanarius and Amara aulica form complex spermatozeugmata bearing conspicuous axial spermatostyles associated with lateral groups of sperm. Individual sperm cells are contained in chambers delimited by laminar extensions of the cortical region of the spermatostyle. Demetrias atricapillus shares the general spermatozeugma structure with the above species, but the anterior spermatostyle region has a different structure and posteriorly, the lateral groups of sperm are separated from the spermatostyle but remain connected to it by peduncles consisting of extensions of the cortical region of the spermatostyle. The sperm of the species examined in the study consist of a short, flat acrosomal cap and, with the exception of the Carabus species, show long nuclei which extend parallel to the axonemes, along the flagella. Two relatively small mitochondrial derivatives and two small accessory bodies flank the axoneme. These bodies become very thick in the posterior flagellar region of D. atricapillus. The study revealed different spermatozeugma models and different sperm organization in the Carabidae family.

几种金龟子甲虫（Insecta，Adephaga）的精子超微结构及其在精子虫中的组织。

研究了来自不同Carabidae部落的7个物种的精子结构。Carabus preslii和Carabus granulatus interstitialis形成精子束（spermatozeugmata），其中传统昆虫精子的头部埋在顶盖（精子体）中，而后鞭毛游离。相反，Pterostichus morio，Pterostichus melas，Pterostichus melanarius和Amara aulica形成复杂的精子，带有明显的轴向精子样式，与精子的侧向相关。各个精子细胞被包含在由精子囊皮质区域的层状延伸所界定的腔室中。变形金刚鹦鹉与上述物种共有大致的精子zeugma结构，但是前精子体样式区域具有不同的结构，并且在后方，精子的侧向群与精子囊分开，但仍通过花序梗与精子囊相连，该花序梗由精子囊皮质区域的延伸组成。该研究中所检查物种的精子由一个短而平坦的顶体顶盖组成，除了Carabus物种外，还显示出沿鞭毛平行于轴突延伸的长核。轴突的侧面有两个相对较小的线粒体衍生物和两个小的附属体。这些身体在滴虫的后鞭毛区变得非常厚。这项研究揭示了Carabidae家族中不同的精子模型和不同的精子组织。该研究中所检查物种的精子由一个短而平坦的顶体顶盖组成，除了Carabus物种外，还显示出沿鞭毛平行于轴突延伸的长核。轴突的侧面有两个相对较小的线粒体衍生物和两个小的附属体。这些身体在滴虫的后鞭毛区变得非常厚。这项研究揭示了Carabidae家族中不同的精子模型和不同的精子组织。该研究中所检查物种的精子由一个短而平坦的顶体顶盖组成，除了Carabus物种外，还显示出沿鞭毛平行于轴突延伸的长核。轴突的侧面有两个相对较小的线粒体衍生物和两个小的附属体。这些身体在滴虫的后鞭毛区变得非常厚。这项研究揭示了Carabidae家族中不同的精子模型和不同的精子组织。
