摘 要: 旨在探明江西区系条件下触形大疣蛛(Macrothele palpator)种内时空演化的规律,细化或核实国外学者有关原蛛在东亚从西南向东北方向逐渐迁移等观点。采用25项主要形态分类特征的比值进行定量聚类分析,获得了该蛛12个样点间演化关系的支序图,并将其与江西各时代地层图进行比对。结果表明:江西各样点间该蛛的地理演化呈分散点线状。得出结论:该蛛形态支序的形成受泥盆纪后地质构造运动影响,其侵入线路可能由赣西南到赣西再到赣中南,真正演化中心在“湘赣岛海”的海区地貌区域,即崇仁相山一带;它经古鄱阳湖盆地断陷及新构造运动等地质作用,在赣中或赣中南向四周扩散,最后朝赣东北方向递进。

Abstract: The geographical evolution of Macrothele palpator in Jiangxi is studied to ascertain a law of this spider speciation within temporal and spatial evolution of the Jiangxi region, to refine or to verify a view put forward by foreign scholars that the original spider had geographic evolution trace gradually from the southwest to the northeast in East Asia. The cladistic chart of 12 point between these taxa was obtained by using the quantitative cluster analysis with the ratio of 25 major morphological classification of M. palpator, and then it was compared with the stratigraphic map of different ages in Jiangxi. The result shows that the geographical evolution of M. palpator displays a decentralized linear pattern, and the conclusion is that there is an effect of tectonic movements after the Devonian on these clades of morphology evolution of M. Palpator. Their invasive line may be from the southwest to the west, and to the central south of Jiangxi, then to real evolution center--the sea landform regions in the “Sea Island, Hunan and Jiangxi”, namely the Xiangshan areas of Chongren. After the fault subsidence of ancient Poyang Lake basin and a series of new tectonic movements, they began to scatter from the central and central south of Jiangxi, and finally to the northeast of Jiangxi.
