中国锯天牛族后翅翅脉研究(鞘翅目,天牛科,锯天牛亚科,锯天牛族)(英文)

对中国锯天牛族的后翅基部关节和后翅翅脉特征进行了研究,发现利用Kukalová-Peck和Lawrence (2004)的后翅命名系统能够很好地对中国锯天牛族后翅翅脉进行命名。但是在中国锯天牛族中,后中脉( MP)和前肘脉(CuA)在后缘并不合并;当前臀脉( AA3)和前肘脉(CuA3 +4)与后肘脉(CuP)相遇时,前臀脉(AA3)消失,前肘脉(CuA3 +4)和后肘脉(CuP)合并,因此楔室(W)仅由肘脉(Cu)的分支脉围成。尽管基部翅关节在研究的各属和各种之间没有表现出差异,但是后翅翅脉在土天牛属Dorysthenes和锯天牛属Prionus不同种类之间差异明显,这些特征包括径室的长宽比例和各边的长度关系、r3存在与否及其长度、后径脉的长度、楔室的长宽比例、以及后中脉(MP3 +4)和前肘脉(CuA3 +4)端部是否分叉等。因此,后翅翅脉特征在土天牛属Dorysthenes和锯天牛属Prionus分种时可能具有分类学意义。

STUDY ON THE VENATION OF PRIONINI (COLEOPTERA,CERAMBYCIDAE,PRIONINAE) FROM CHINA

In the study,the venation and the articulation of hind wing of Chinese Prionini were studied.We found articulation at wing base in Prionini was consisted of HP,1 Ax.2Ax,FM and 3Ax like that of other coleopteran.Although a variety of wing-vein naming systems about hind wing of Cerambycidae adults had been proposed during the past 100 years,the naming system of Kukalov?Peck and Lawrence(1993,2004)was more reasonable and better than that ot others in explanation venation of Prionini.However,branches of MP and CuA do not fuse together close to the posterior wing margin in Prionini.AA3ends on CuP instead of CuP ending on AA3 or the combination of these veins when they meet.Branches of cubitus form the wedge cell in Prionini. All genera and species have identical articulation in hind wing and all articulations have the sarte shape.Nevertheless.several characters of venation may be useful to identify species in genera Dorysthenes and Prionus.
