摘要(Abstract)：

<正> 我国的大锥蚤Macrostylophora Ewing,1929,虽早有报导,但种类不多。至1977年增加到8种,近几年又有更多的新种发现,已成为有18种和亚种的大属。它们的形态特征具有明显的多样性,地理分布从东洋界为主向北达到古北界。其宿主达20余种之多。因此有必要对这个较复杂较大的属进行种团划分,并对其地理分布和宿主关系作分析和阐述。
Acccrding to recent investigations, therc are 18 forms in the genus Macro- stylophora in China. As their diagnostic characters are so divergent, that it seems necessary and possible to divide them into species-groups, as follows: Ⅰ. aeretesites-group: aeretesites Li, Chen & Wei, 1974, bispiniforma Li, Hsieh and Yang, 1976 and Luchunensis Huang (in press). Ⅱ. microcopa--group: microcoga Li, Chen & Wei, 1974, baoshanensis Li- & Yah, 1980, congjiangensis Li & Huang, 1979, gansuensis Chang & Ma (in press) , hastatus hainanensis Liu & Pan (in press) and menghaiensis Li, Wang & Hsieh, 1964. Ⅲ. euteles-group: euteIes (J. & R., 1911), abazhouensis Liu, Wu & Chang, (in press), cuii cuii Liu, Wu & Yu, 1964, cuii jiangkouensis Li & Huang, 1979 and heheiensis Liu, Wu & Chang, 1979. Ⅳ. exilia-group, exilia Li, Wang & Hsieh, 1964, Liae Wang, 1957, and trispinosus (Liu, 1939). Since most of the fleas of the genus Macrostylophora are Oriental and the distribution of many of them are so restricted in a geographical area, that one might assume that they were more or less endemic. Recent investigations reported 7 out of 18 of the species Palaearetic. This strongly supports Trauo's suggestion (1972) that "the morphological taxonomic features of Macrostylophora clearly indicate Palaearctic origin". Similar to some ceratophylid flea genera, that they were "originated in the Northern Heimsphere, and that the Oriental members were derived from Palaearctic roots." Macrostylophora fleas (tab. Ⅰ.) are primarily parasites of Sgiuridae and Pe- tauristidae, 17 out of the 18 known forms are assogiated with the former and 3 on the later, among which 2 of them infest both of them. Murids are cons- idered as secondary hosts, for 6 of the Sciurid fleas shared with them. Besides, 2 of them are fount on Tupeia glis, the habitat and behavior of which are simi- lar to Sgiurids, hence are considered as temporary even secondary hosts.
