摘要
到1988年,我国已记载步甲科35族、198属、1717种、258亚(变)种和变型。其中,古北界区系成分占优势,东洋界区系成分复杂,西南区区系成分在一定程度上显示出从古北界垂直向下到东洋界的过渡状况,并存在中国特有的区系成分。古北界与东洋界东段的分界线大约在北纬25°较符合我国步甲科区系分布的实际情况。
By 1988, 35 tribes, 198 genera, 1717 species and 258 subspecies (var., ab.) of carabids had been recorded in China. The earabid components of the Palearetie Region are predominant as compared with those of the Oriental Region. The components of the Oriental Region arc characterized by high diversity. The components of Xinan Region show a transitional state in which the Palearetie components move down southward into the Oriental Region. In this region exist some unique groups on the earth. The east boundary line between the Palearetie Region and the Oriental Region is located about 25°N.
