Abstract

Bayesian and parsimony phylogenetic analyses of combined and partitioned datasets of molecular (partial sequences of 28S, wg, COI, and CAD) and morphological (51 characters of adults) data for exemplar taxa of five outgroup and 76 ingroup abacetine carabids resulted in a monophyletic Loxandrina Erwin & Sims, 1984 that is split into Australian and American clades. The genus Loxandrus LeConte, 1853 as previously delimited is not monophyletic relative to numerous genus-level taxa in Abacetini Chaudoir, 1873 and is restricted to a subgenus of North American species. A reclassification and nomenclatural changes for the subtribe that are consistent with the phylogeny are provided. Three genera are removed from Loxandrina: Aulacopodus Britton, 1940 moved to Pterostichini Bonelli, 1810; Cosmodiscus Sloane, 1907 and Tiferonia Darlington, 1962 moved to Abacetina. Based on the phylogenetic relationships and nomenclatural priority only four genera are recognized in Loxandrina: Cerabilia Laporte, 1867, Zeodera Laporte, 1867, Pediomorphus Chaudoir, 1878, and Oxycrepis Reiche, 1843. All other previously recognized genera are treated as subgenera. The classification change created eight secondary homonyms that are resolved by the proposal of the following: Oxycrepis gebi, replacement name for O. balli (Straneo, 1993); O. amatona, replacement name for O. matoana (Straneo, 1993); O. xiproma, replacement name for O. proxima (Straneo, 1993); O. rasutulis, replacement name for O. suturalis (Straneo, 1993); O. laevinota, replacement name for O. laevicollis (Bates, 1871); O. arvulap, replacement name for O. parvula (Straneo, 1951); O. noaffine, replacement name for O. affinis (Straneo, 1991); O. alutona, replacement name for O. notula (Tschitschérine, 1901). An overview of the morphological characteristics and diagnostic features of Loxandrina taxa is provided. A key and habitus images are provided for identification of genera and subgenera. The possible historical biogeography of the group is discussed in light of their phylogenetic relationships and past geological events.

黄鳝属群分类系统发育及分类(鞘翅目，蠓科，蠓科)

对5个外群和76个内群珠贝属的典型分类群的分子（28S、wg、COI和CAD的部分序列）和形态（51个成体特征）数据的组合和分割数据集进行贝叶斯和简约系统发育分析，得出了一个单系Loxandrina Erwin&Sims，1984，该单系被分为澳大利亚和美国分支。之前界定的Loxandrus LeConte属，1853相对于Abacetini Chaudoir，1873中的许多属级分类群不是单系的，并且仅限于北美物种的一个亚属。提供了与系统发育一致的亚群的重新分类和命名变化。Loxandrina中删除了三个属：Aulacopodus Britton，1940年移到Pterostichini Bonelli，1810年；1907年的斯隆和1962年的达林顿搬到了阿巴切蒂纳。根据系统发育关系和命名优先级，在亚历山大藻中只有四个属被识别：Cerabilia Laporte，1867，Zeodera Laporte（1867），Pediomorphus Chaudoir（1878）和Oxyceripis Reiche（1843）。所有以前公认的属都被视为亚属。分类的改变产生了八个次要的同音异义词，通过以下建议解决：Oxyceris gebi，O.bali的替代名称（Straneo，1993）；O.amatona，O.matoana的替代名称（Straneo，1993）；O.xiproma，O.proxima的替代名称（Straneo，1993）；O.rasutulis，O.suturalis的替代名称（Straneo，1993）；O.laevinota，O.laevicollis的替代名称（Bates，1871）；O.arvulap，O.parvula的替代名称（Straneo，1951）；O.noaffine，O.affinis的替代名称（Straneo，1991）；O.alutona，O.notula的替代名称（Tschitschérine，1901）。综述了山柰属分类群的形态特征和诊断特征。为属和亚属的识别提供了一个关键的和习惯的图像。根据它们的系统发育关系和过去的地质事件，讨论了该类群可能的历史生物地理学。

期刊介绍： Founded in 1857 as Berliner Entomologische Zeitschrift, Deutsche Entomologische Zeitschrift is one of the World''s oldest international journals of systematic entomology. It publishes original research papers in English on the systematics, taxonomy, phylogeny, comparative morphology, and biogeography of insects. Other arthropods are also considered where of relevance to the biology of insects. The geographical scope of the journal is worldwide. Deutsche Entomologische Zeitschrift (DEZ) is dedicated to provide an open access, high-quality forum to contribute to the documentation of insect species, their distribution, their properties, and their phylogenetic relationships. All submitted manuscripts are subject to peer-review by the leading specialists for the respective topic. The journal is published in open access high-resolution PDF, semantically enriched HTML and machine-readable XML versions.
