一龄蚤幼破卵器形态及其分类意义

本文描述尚未见报的14种一龄蚤幼的破卵器形态(附有插图和图版),并结合既往资料讨论了它们在蚤类分类中的意义。 无论是破卵器的形状、大小,还是其孵化刺的形状、着生部位及发达程度,在不同科、属、种之间都有不同程度的差别,尤其在较高的分类阶元上差别甚大;但在同种的不同亚种,同属的不同种,乃至同科的不同属之间又存在一定的相似性。因此,一龄蚤幼的破卵器形态是蚤幼分类的重要特征之一。

STUDIES ON THE SHAPE OF EGG BURSTER OF FIRST INSTAR LARVAE OF FLEA AND ITS TAXO-NOMIC SIGNIFICANCE

The shapes of egg burster of first instar larvae of 14 species belonging to 11 genera out of 4 families of flea, i. e. Chaetopsylla lasia, Neopsylla democratica, N. mana, Amphipsylla anceps anceps, A, primaris beigangensis, Frontopsylla elatoides elatoides, Mesopsylla eucta shikho,Ophthaltnopsylla volgensis volgensis, Ceratophy-llus enejdei tjanshani, Citellophilus tesquorum altaicus, Callopsylla caspius, No-sopsyllus laeviceps laeviceps, N. consimilis and Oropsylla silantiewi, which were not reported, are described (with figures and plates) and its significance on taxonomy of flea is discussed in combination with past data.There were some differences to different extent either in the shape and size of egg bursters or in the shape, location and developed level of hatching spines Par-ticulary, they were more obvious in higher classificatory units. However, there were certain similarities among different subspecies of same species, different species of same genus and different genera of same family. Therefore, the shape of egg berster is one of the classificatory characters of flea larvae.
