本文对产于亚马孙山脉南部的巨蜥属(Torquatus Group)蜥蜴进行了系统的订正。在分析了5个不同类型的斑点蜥蜴并存的地区的分生特征后，共识别出11种蜥蜴，其中7种为新记录。给出了每个种的诊断、描述和地理分布，并提出了种的人工检索表。在生态学上，似乎有两种物种组合：第一种包括地理分布广泛的所有物种，第二种包括分布有限的物种，通常局限于山区或沙土地区。可能目前的气候条件更适合第一组，而不是第二组。提出了一种基于一对物种近期地理生态学的模型来解释扭角藻类某些物种目前的复杂分布。研究了松材线虫和松材线虫的地理分化，并提出了一系列事件来解释其起源、生态分化和进化。
This paper is a systematic revision of the lizards of the genus Tropidurus (torquatus group) occurring south of the Rio Amazonas. Following an analysis of meristic characters in five areas where lizards with different types of mite pockets occur synpatrically, eleven species are recognized, seven of which described as new. Diagnoses, descriptions and geographic distribution are given for each species, and an artificial key to species is presented. Ecologically, there seem to be two species assemblages: the first includes all species with wide geographic distribution, and the second includes species with restricted distributions, usually limited to mountain or sandy soil areas. Probably present climatic conditions are more suitable for the first group, than for the second. A model based on the geographic ecology of the recent past of a pair of species is proposed to explain the present complex distribution of some species of the torquatus group. The geographic differentiation of T. torquatus and T. hygomi is studied and a sequence of events proposed to explain its origin, ecologic differentiation and evolution.
