摘要
基于16属65种琵甲(含新记述7属)的防御腺特征,探讨了琵甲族(鞘翅目:拟步甲科)的属级系统发育关系。通过对这些种的防御腺着生位置、形状、长度、宽度、囊体间距、囊壁厚度、囊壁花纹、囊壁褶皱等特征进行解剖测量和分析,归纳出族、属级特征。利用SPSS19.0和Hennig86(1.5版)两个软件对选定特征进行聚类分析和系统进化分析,得出琵甲族16属的进化关系为:Prosodes>Blaptogonia>Tagonoides>Thaumatoblaps>Caenoblaps>Agnaptoria>Asidoblaps>Coelocnemodes>Dila>Gnaptor>Blaps>Pseudognaptorina>Nalepa>Belousovia>Gnaptorina>Itagonia。基于防御腺形态学数据的琵甲族系统发育分析结果将琵甲族16个属清楚地分开,表明其在分类上具有重要价值。
The phylogenetic systematics of 65 species of Blaptini ( Coleoptera : Tenebrionidae) belonging to 16 genera (including 7 new recorded genera) was dealt with based on the structure of defensive glands. The characteristics of the glands at the genera and tribal level including gland position, shape, length, width, distance between the two glands, thickness of glands, surface fingerprint whorl and wrinkles were summarized. The phylogenetic relationship of the 16 genera was established using SPSS19.0 and Hennig86 program (version 1.5). The resuh showed that the evolutionary relationship should be as follows: Prosodes 〉 Blaptogonia 〉 Tagonoides 〉 Thaumatoblaps 〉 Caenoblaps 〉 Agnaptoria 〉 Asidoblaps 〉 Coelocnemodes 〉 Dila 〉 Gnaptor 〉 Blaps 〉 Pseudognaptorina 〉 Nalepa 〉 Belousovia 〉 Gnaptorina 〉 hagonia. The result supports the geographic distribution feature of this group. The 16 genera of Blaptini were clearly separated based on the phylogeny of defensive glands' morphological data, suggesting that these characteristics have important value in taxonomy.
