Abstract

Abstract The genus Baripus Dejean is a carabid beetle endemic to southern South America, inhabiting grassland and shrub habitats in mountain and lowland areas. In this work, the phylogeny of the genus is updated and new species restricted to isolated mountains from the Patagonia Biogeographic Province are described. The cladistic analysis showed that the new mountain species comprise a monophyletic clade with five other species. Within this group, the species are arranged in two internal clades. Each clade contains one or two lowland species with a wide distribution range and the remaining species with microendemic distribution on each mountain system. Their distribution pattern suggests that mountain species of Baripus could have originated since (by) the end of the Cenozoic when the mountains uplifted and acted as a refuge for populations of lowland species that remained isolated and later became differentiated from one another. Based on morphological and cytochrome c oxidase subunit I molecular data, Baripus (Cardiophthalmus) palauco, sp. nov., Baripus (Cardiophthalmus) tromen, sp. nov., Baripus (Cardiophthalmus) aucamahuida, sp. nov. and Baripus (Cardiophthalmus) payun, sp. nov. are described and a key to all currently known species of Baripus (Cardiophthalmus) is provided.

南美Baripus属（鞘翅目：Carabidae:Broscini）的系统发育与巴塔哥尼亚生物地理省北部山区新物种的描述

Baripus Dejean属是南美洲南部特有的一种甲虫，生活在山地和低地的草原和灌木生境中。本文更新了该属的系统发育，并描述了局限于巴塔哥尼亚生物地理省孤立山区的新种。枝系分析表明，该山地新种与其他5个种组成一个单系枝系。在这一组中，物种被安排在两个内部分支中。每个分支包含1 - 2个分布范围广的低地种，其余种在每个山地系统中都有微地方性分布。它们的分布模式表明，巴利普斯的山地物种可能起源于新生代末期，当时山脉隆起，成为低地物种种群的避难所，这些低地物种一直处于孤立状态，后来彼此分化。基于形态学和细胞色素c氧化酶亚基I分子数据，描述了Baripus (Cardiophthalmus) palauco, sp. nov.， Baripus (Cardiophthalmus) tromen, sp. nov.， Baripus (Cardiophthalmus) aucamahuida, sp. 11 .和Baripus (Cardiophthalmus) payun, sp. 11 .，并提供了目前已知的所有Baripus (Cardiophthalmus)种的关键。

期刊介绍： Invertebrate Systematics (formerly known as Invertebrate Taxonomy) is an international journal publishing original and significant contributions on the systematics, phylogeny and biogeography of all invertebrate taxa. Articles in the journal provide comprehensive treatments of clearly defined taxonomic groups, often emphasising their biodiversity patterns and/or biological aspects. The journal also includes contributions on the systematics of selected species that are of particular conservation, economic, medical or veterinary importance. Invertebrate Systematics is a vital resource globally for scientists, students, conservation biologists, environmental consultants and government policy advisors who are interested in terrestrial, freshwater and marine systems. Invertebrate Systematics is published with the endorsement of the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Australian Academy of Science.
