种级异物同名处理及属名变动影响分析

讨论《国际动物命名法规》(简称《法规》)关于种级单元异物同名的处理及相关规定。以斧须隐翅虫亚科Oxyporinae的同名问题为例，笔者分析了属级单元名称变动对种级单元同名关系的影响。一些古老的属级单元有很长且比较复杂的分类历史，深入分析可将各类变化归纳为六类，其中三类与原同名有关，二类与后同名有关，余一类不再影响种级同名关系。文中讨论了第4版《法规》中与种级同名关系有关的若干重要变动，通过分析比较，说明《法规》的这类变动如何影响动物分类名称的稳定性与正确性。这些分析，可望有助于避免产生新的次同名，也有助于正确恰当地解决已有的同名问题。

ON HOMONYMY OF SPECIES-GROUP NAMES-ANALYSIS, TREATMENT AND INFLUENCES OF GENUS-NAME CHANGES

This paper introduces how homonyms of species-group names should be treated according to the fourth edition of the ICZN (International Code of Zoological Nomenclature). Examples from the Oxyporinae, a rove beetle subfamily, are used to analyse and illustrate the influences of genus-group name changes on the homonymy of species-group taxa. In spite of the complex histories of some long-existing genus-group taxa, relevant taxonomic changes can be categorized into six different types, of which three are related to primary homonymy, two to secondary homonymy, and one has no longer anything to do with species-group homonymy. Some important changes in the fourth edition of the ICZN dealing with species homonymy are discussed, and their essential influences on stability and correctness of taxonomic names analyzed. The author hopes this paper will help authors avoid the creation of junior homonyms and also aid the rectification of existing problems of homonymy according to proper taxonomic principles and the ICZN guidelines.
