The sperm ultrastructure of the bean-weevil (Bruchinae) was studied to verify the congruence of the new position of the subfamily within Chrysomelidae. The results indicated a positive answer to the question supporting a close relationship between Chrysomelidae and Curculionidae, a finding confirmed also by molecular data. Moreover, the sperm morphology of , a member of Melyridae (Cleroidea) allowed to confirm the different sperm organization between members of this superfamily and Phytophaga (Chrysomeloidea + Curculionoidea). While studying the spermiogenesis of . i, some sperm cysts showed aberrant cells provided with two flagella in the same plasma membrane. These aberrant sperm could be the result, during early spermiogenesis, of irregular processes involving the canal rings between spermatids.

Spermophagus kuesteri Schilsky, 1905（叶甲科，Bruchinae）精子超微结构及 Cucujiformia 超科关系的思考

研究了豆象甲科（Bruchinae）的精子超微结构，以验证该亚科在叶甲科中新位置的一致性。结果对支持叶甲科和象甲科之间密切关系的问题给出了肯定的答案，这一发现也得到了分子数据的证实。此外，Melyridae（Cleroidea）成员的精子形态可以证实该超科成员与Phytophaga（Chrysomeloidea + Curculionoidea）成员之间的精子组织不同。在研究精子发生时。 i，一些精子囊肿显示出在同一质膜上具有两个鞭毛的异常细胞。这些异常精子可能是早期精子发生过程中涉及精细胞之间管环的不规则过程的结果。
