基于防御腺的中国琵甲族Blaptini系统发育分析(鞘翅目:拟步甲科)

Phylogenetic analysis of the tribe Blaptini (Coleoptera: Tenebrionidae) in China based on the defensive glands

根据琵甲族Blaptini11属 5 8种防御腺的着生位置、形状、长度、宽度、囊袋距离、表面花纹等特征归纳出属级和族级特征。每属选 1代表种 ,各选 6个典型特征 ,组成特征矩阵 ,用Hennig 86 (1 5版 )软件初步确定了琵甲族各属的系统发育关系 ,得出琵甲族属级进化趋势为 :宽琵甲属Blaptogonia >侧琵甲属Prosodes>异琵甲属Thaumatoblaps>琵甲属Blaps>亚琵甲属Asidoblaps>齿琵甲属Itagonia >贞琵甲属Agnaptoria >小琵甲属Gnaptorina >地琵甲属Dila >新琵甲属Neoblaps >乾琵甲属Coelocnemodes。所有研究标本保存在河北大学博物馆。

This paper deals with the phylogenetic systematics of 11 genera of the tribe Blaptini (Coleoptera:Tenebrionidae) from China based on defensive gland structure. We summarized the characteristics of the glands at the generic level according to position, shape, length, width, distance between the two glands and surface fingerprint whorl, and used this information to compile a key to genera. The phylogenetic relationship of the 11 genera has been established using the HENNIG 86 program (version 1 5). The result shows the evolutionary route should be as follows: Blaptogonia > Prosodes> Thaumatoblaps> Blaps> Asidoblaps> Itagonia> Agnaptoria> Gnaptorina> Dila> Neoblaps> Coelocnemodes . All specimens are deposited in the Museum of Hebei University.
