摘要

Tropterus Solier，1849年，隶属于南美洲南部，在分类学上进行了修订。描述了六个新种：T.peckoromsp。11月，T.robustusp。nov.，T.canaliculussp。11月，T.trisinatussp。11月，T.minimucrosp。nov.和T.fieldianussp。nov.Catapilianus Merizodus Jeannel，1962，与T.montagnei-Solier同义，1849。Lectotype被指定为T.montagnei、T.giraudyi-Solier、T.duponcheli-Solier和T.nitidus-Solier（=T.duponchelii）。秘鲁Tropterus peruvianus Straneo被认为是一个名称dubium，其身份和分类位置将通过新类型命名得到证实。根据37个形态特征假设了Troopterus spp.之间的系统发育关系，并根据简约标准分析了这些特征的分布，在来自澳大利亚新南威尔士州的Troopters及其adelphotaxon之间建立了分支图根。相对于总体属属属分布，该类群的特殊性主要发生在有限的地理范围内，有三对姐妹物种共有。然而，在两个系统发育史实例中，可以观察到以Nothofagus oblica（Brisseau de Mirbel）为特征的更北部的硬叶林中的分类群与以N.dombeyi（Brisseau-de Mirbel）为主的瓦尔迪维亚和北巴塔哥尼亚雨林中的分类组之间的系统发育差异。利用特定的采集地点记录，表明Troopterus甲虫与Glypoloma Jeannel（鞘翅目，Staphylinidae）、Anaballetus Newton、Švec&Fikáček（鞘翅目的，Leiodidae）、Andotypus Spangler（鞘翅科，Hydrophilidae）和Novonothrus Balogh（Acari，Oribatida）等物种同时采集。这些协调一致的生态现象记录了诺特霍法格斯森林落叶层群落的凝聚力。这些属加上其他瓦尔迪维亚雨林无脊椎动物分类群都表现出澳大利亚间断的生物地理模式，证实了南美洲南部和澳大利亚的诺霍法格斯森林之间的跨南极替代关系。雄性生殖不对称被证明是Troopterus的一种突触形态，尽管雌性生殖道保留了在所有其他moriomorphine分类群中观察到的类同形态取向。

Revision of Tropopterus Solier: A disjunct South American component of the Australo-Pacific Moriomorphini (Coleoptera, Carabidae)

Tropopterus Solier, 1849, precinctive to southern South America, is taxonomically revised. Six new species are described: T. peckorumsp. nov., T. robustussp. nov., T. canaliculussp. nov., T. trisinuatussp. nov., T. minimucrosp. nov., and T. fieldianussp. nov.Merizodus catapileanus Jeannel, 1962, is synonymized with T. montagnei Solier, 1849. Lectotypes are designated for T. montagnei, T. giraudyi Solier, T. duponchelii Solier, and T. nitidus Solier (= T. duponchelii). Tropopterus peruvianus Straneo is noted as a nomen dubium, with its identity and taxonomic placement to be substantiated via neotype designation. Phylogenetic relationships among Tropopterus spp. are hypothesized based on 37 morphological characters, the distributions of which are analyzed under the parsimony criterion, with the cladogram root established between Tropopterus and its adelphotaxon from New South Wales, Australia. Speciation in the group has occurred predominantly at a limited geographical scale relative to the overall generic distribution, with three pairs of sister species sympatric. However phylogenetic divergence between taxa in the more northern, sclerophyllous forest characterized by Nothofagus obliqua (Brisseau de Mirbel) and those occupying the Valdivian and North Patagonian Rain Forest dominated by N. dombeyi (Brisseau de Mirbel) is observed in two instances of phylogenetic history. Using specific collecting locality records, it is shown that Tropopterus beetles have been collected syntopically and synchronically with species of Glypholoma Jeannel (Coleoptera, Staphylinidae), Anaballetus Newton, Švec & Fikáček (Coleoptera, Leiodidae), Andotypus Spangler (Coleoptera, Hydrophilidae), and Novonothrus Balogh (Acari, Oribatida). These concordant ecological occurrences document a cohesive Nothofagus forest leaf-litter community. These genera plus other Valdivian Rain Forest invertebrate taxa all exhibit an Austral disjunct biogeographical pattern that corroborates trans-Antarctic vicariance between the Nothofagus forests of southern South America and Australia. Male genitalic antisymmetry is shown to be a synapomorphy of Tropopterus, though the female reproductive tract retains the plesiomorphic orientation observed in all other moriomorphine taxa.

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.
