云南食植瓢虫族的系统位置及属间关系

本文对云南食植瓢虫族昆虫形态学,特别是跗爪基齿,上颚侧齿,雌、雄性外生殖器等性状的研究,讨论了本族的属间关系;应用分支系统学的原理和方法,对本族系统位置的研究进行了尝试。采用最大同步法对本族5个属8个性状状态进行了分支分析,其结果与传统分类结果有一定的差异。结论支持将食植瓢虫属分为3个亚属,其中2个为新亚属。

STUDIES ON THE SYSTEMATIC POSITION AND GENERIC RELATIONSHIPS OF THE TRIBE EPILACHNINI (COLEOPTERA: COCCINELLIDAE) FROM YUNNAN

This paper deals with the systematic position and generic relationships of the tribe Epilachnini based on the morphological characteristics, especially on the basal teeth of the tarsal claws, lateral teeth of mandibles, on male and female genitalia. Applying cladistic methodology, the authors also discussed phylogenetic relationships within the tribe. Five genera, i. e. Epilachna, Afidenta, Afissula, Henosepilachna, Afidentula, are selected as the taxa for cladistic analysis. A taxonomy based OH the cladogram is different from the orthodoxa one. The genus Epilachna should be divided into three phylogenetic groups. A subgeneric rank for the three groups is accepted in this treatment. Two new subgenera of Epilachna, i. e. Aparodentata Cao et wang, Uniparodentata Cao et Wang, are described.
