赞青尺蛾属修订及其分布格局分析（鳞翅目：尺蛾科：尺蛾亚科）

本文对赞青尺蛾属Xenozancla Warren, 1893进行研究，重新描述了属、种特征，总结了属的鉴别特征；描述了种内雄外生殖器的变化并附图，提供了成虫形态、外生殖器图。提出银尺蛾属Yinchie Yang, 1978和枣灰银尺蛾Y. zaohuiYang, 1978 分别是赞青尺蛾属Xenozancla 和赞青尺蛾X. vericolor Warren 的新异名，并为赞青尺蛾X. vericolor Warren指定了选模。同时，采用临近距离平均法（mean propinquity method）结合GIS技术绘制了赞青尺蛾属分布格局图，并据此分析了其分布格局和分布特点，结果表明：该属为亚洲东部特有属，呈西南 华北走向；它在中国华北、华中、西南地区至印度可能存在一个连续的分布区，其分布格局应属于东洋界的东南亚热带-亚热带型。

Revision of the genus Xenozancla Warren, 1893 (Lepidoptera:Geometridae: Geometrinae) with an analysis of its distribution pattern

The genus Xenozancla Warren,1893 and its type-species X.vericolor are redescribed,and the diagnostic characters of the genus is given.Morphological characters of adult,including those of appearances of dorsal and ventral view,wing veins and genitalia,are figured;variations of male genitalia within species are discussed in detail and illustrated.Two new synonyms are proposed:Yinchie Yang 1978 as a new junior synonym of Xenozancla Warren 1893,and Yinchie zaohui Yang 1978 as a new junior synonym of Xenozancla versicolor Warren 1893.The lectotype is designated for X.versicolor Warren.The biogeographical features and distribution pattern of the genus are discussed on the basis of using mean propinquity and GIS methods.The results show that Xenozancla is endemic to eastern Asia.Its distributional area may be continuous from North China to Southwest China and India.Its distribution pattern should belong to South-East Asian tropical-subtropical type of the Oriental realm.
