虎凤蝶属雄性外生殖器超微结构的比较（鳞翅目：凤蝶科）

运用扫描电镜观察了虎凤蝶属现有4种雄成虫的外生殖器。结果表明：中华虎凤蝶Lueh-dorfia chinensis Leech 、长尾虎凤蝶L. longicaudata Lee、乌苏里虎凤蝶L. puziloi Erschoff和日本虎凤蝶L. japonica Leech雄性外生殖器的一般形态结构相似，而其抱器、钩状突、阳茎、阳茎轭片的超微结构存在着差异，这些特征可作为鉴定的依据。通过对雄性外生殖器形态结构的比较，以及有关结构参数的聚类分析，讨论了4种虎凤蝶的亲缘关系。作者认为，中华虎凤蝶具有最原始的结构特征，可能较接近该属祖先，长尾虎凤蝶则与其较近缘；乌苏里虎凤蝶与日本虎凤蝶相对较近缘，与前两种差异略大。

ULTRASTRUCTURAL COMPARISONS AMONG MALE EXTERNAL GENITALIAS OF FOUR LUEHDORFIA SPECIES (LEPIDOPTERA: PAPILIONIDAE)

The ultrastructures of male external genitalias of Luehdorfia species were observed with scanning electron microscope. For these four Luehdorfia species, i.e. L. chinensis Leech, L. longicaudata Lee, L. puziloi Erschoff and L. japonica Leech, the appearances of whole male external genitalias are similar, and their ultrastructures of harpago, uncus, aedeagus and juxta are markedly different. These ultrastructural characters could be used for identifying the species of Luehdorfia. According to the results from comparing the differences in morphological structures of male external genitalias and clustering analysis of the parameters about male external gentalias of these butterflies, the relationship among these four Luehdorfia species is discussed. It is suggested that L. chinensis with the most primitive structure of male external genitalia has a near relation with L. longicaudata and perhaps is the nearest to the ancestor of Luehdorfia. In contrast to both L. chinensis and L. longicaudata, nearer relation exists between L. puziloi and L. japonica.
