Abstract

In the present study, the taxonomic status of Microlophus heterolepis and M. yanezi is reviewed. Although M. heterolepis is one of the identifi ed species present in Chile, incongruity about their geographical distribution, habitat and ecological characteristics are evident, so its true determination is an issue. Type materials and original descriptions of M. heterolepis were compared with its closest species M. yanezi, and morphological (scaling, lineal morphometric and geometric morphometric) and molecular analysis (cytb) were performed. The results show that: 1) M. heterolepis was originally described for the locality of Tacna in Peru, 2) morphological descriptions by Donoso-Barros (1966) correspond to a lizard in the desert, but their ecological characteristics were described erroneously as a kind of rocky intertidal, and 3) there is agreement with previous authors that both species are valid. However, based on our results, the geographical distribution of M. heterolepis is restricted to Peru, while M. yanezi is a validly described species from Chile.

Microlophus heterolepis (Wiegmann, 1835)和Microlophus yanezi (Ortiz, 1980)的分类鉴定:智利和秘鲁内陆沙漠的两个好物种

本文综述了异长小蝽和雅氏小蝽的分类学地位。虽然是智利现存的已鉴定种之一，但其地理分布、生境和生态特征存在明显的不一致性，因此其真正的鉴定是一个问题。对其类型资料和原始描述进行了比较，并进行了形态学分析(尺度学、线性形态学和几何形态学)和分子分析(cytb)。结果表明:1)M. heterolepis最初是在秘鲁的Tacna地区被描述的;2)Donoso-Barros(1966)的形态描述与沙漠中的一种蜥蜴相对应，但其生态特征被错误地描述为一种岩石潮间带;3)两个物种都是有效的，这与前人的观点一致。然而，根据我们的研究结果，M. heterolepis的地理分布仅限于秘鲁，而M. yanezi是智利的一个有效描述种。

期刊介绍： GAYANA is a scientific journal published by Universidad de Concepción, Chile. It is the modern version of Gayana Oceanología and Gayana Zoología. Therefore its numeration starts at volume 63(1). GAYANA covers all aspects of zoology and oceanographic research. It is structured in five sections, defined by subject or discipline: Ecology, Biodiversity and Taxonomy, Earth Sciences, Evolutionary, and Applied Biology and Environmental Biology. Each section is in charge of an editor who receives and manages the manuscripts sent for evaluation in close collaboration with the editorial board.
