Phylogeny and Revision of the Hawaiian Carabidae: Platynini Beetles

对夏威夷步甲虫(鞘翅目：步甲科)进行分类修订所需的实地工作正在进行中，以便准确描述动物区系，并建立基线多样性数据，用于监测濒危栖息地的状况。将对Platynini部落的夏威夷种进行修订，在135种以上的物种中描述20多种新种。将开发识别钥匙和图解，以便识别所有夏威夷步甲属和夏威夷的普拉蒂尼属物种。基于对一组全面的成虫形态特征的简约分析，将使用铂族物种的分支假说来研究该类群的物种形成模式。使用太平洋和亚洲外群进行外群分析，可以确定夏威夷铂族的来源。在分支假说的背景下考察人物，提供关于他们潜在的进化基础的信息。将对夏威夷部落的第二种步甲科和其他主要放射科的成虫形态特征进行全面调查。这项调查为该群体的分支假说奠定了基础，并允许对进化过程进行平行测试，就像对普拉蒂尼尼所做的那样。

Field work necessary for taxonomic revision of the Hawaiian carabid beetles (Coleoptera: Carabidae) is underway, permitting accurate characterization of the fauna and establishing baseline diversity data for use in monitoring the status of endangered habitats. Hawaiian species of tribe Platynini will be revised, with over 20 new species described among the over 135 species. Identification keys and illustration permitting identification of all Hawaiian carabid genera and Hawaiian species of Platynini will be developed. A cladistic hypothesis of platynine species based on parsimony analysis of a comprehensive set of adult morphological characters will be used to investigate speciation patterns in the group. Outgroup analysis using Pacific and Asian outgroups allows identification of the source of Hawaiian platynines. Characters are examined in the context of the cladistic hypothesis, providing information on their underlying evolutionary basis. A comprehensive survey of adult morphological characters will be undertaken for Hawaiian species of tribe Psydrini, the second and other major radiation of Carabidae on the islands. This survey forms the basis for a cladistic hypothesis for the group, and permits parallel tests of evolutionary process as accomplished for Platynini.
