摘要
文中描述了四眼小蠹属Ｐｏｌｙｇｒｐｈｕｓ三新种：枫杨四眼小蠹Ｐｏｌｙｇｒｇｐｈｕｓｐｔｅｒｏｃａｒｙｉｓｐ．ｎｏｖ，麻栎四眼小蠹Ｐ．ｑｕｅｒｃｉｓｐ．ｎｏｖ，阔叶四眼小蠹Ｐ．ａｍｐｌｉｆｏｌｉｕｓｓｐ．ｎｏｖ。作者改换了Ｐ．ｒｕｄｉｓＥｇｇｅｒｓ，１９３３的亚种划分方式，认为过去采用的对Ｐ．ｒｕｄｉｓＥｇｇｅｒｓ的亚种划分方式是错误的，因而出现了种间和亚种间形态特征的混淆现象和地理分布区不明确的现象，从而肯定了以下两个种和两个亚种均为Ｐ．ｒｕｄｉｓＥｇｇｅｒｓ的同物异名，即：Ｐ．ｚｈｕｎｇｄｉａｎｅｎｓｉｓＴｓａｉｅｔＹｉｎ，１９６５；Ｐ．ｓｑｕａｍｅｕｓｙｉｎｅｔＨｕａｎｇ，１９８１；Ｐ．ｒｕｄｉｓｌｉｋｉａｎｎｇｅｎｓｉｓＴｓａｉｅｔＹｉｎ，１９６５；和Ｐ．ｒｕｄｉｓｒｅｔｉｖｅｎｔｒｉｃｕｌｕｓＴｓａｉｅｔＹｉｎ，１９６５。作者在统计大量标本的基础上，找出了新的划分亚种的形态特征和地理分布区划，从而描述了一新亚种，露滴四眼小蠹河西亚种Ｐ．ｒｕｄｉｓｈｅｘｉｅｎｓｉｓ１ｓｓｐ．ｎｏｖ。作者在文后做了四眼小蠹属种的检索表，其中包括分布于我国的１５个种和亚种。
This paper is a studying report on Chinese Polygraphus Erichson. Firstly, the authors describe 3 species new to science: P. pterocaryi, P. amplifolius and P. querci. Secondly,they have changed the division of subspecies in species Polygraphus rudis Eggers, 1933.They have found that P. rudis likiangensis Tsai et Yin, 1965 P. rudis retiventriculus Tsai et Yin, 1965, P. zhungdianensis Tsai et Yin, 1965 and P. squanzeus Yin et Huang, 1981 are all synonyms of P. rudis Eggers, because as the collected specimens have been increased,durinig a period of quite a few years, to a number of more than 2000, the differences of diagnosis characters and the differences of the geographical distributions of each species and subspecies are becoming obscure and overlapping. However, they discovered that P. radis Eggers is still existing in two subspecies froms:P. rudis rudis Eggers and P. rudis hexiensis ssp. nov. The diagnosis characters of the two subspecies, which they have discovered on the basis of studying thousands of specimens, are the thickness of body vestitutre and the average body length. The boundary line of geographical distributions of the two subspecies is the northern boundary of Hengduanshan Mountains. Thirdly, the authors present a key of the genus Polygraphus, which includes all the 15 species and subspecies in China.
