Abstract

Abstract Medetera Fischer von Waldheim is the most speciose genus in the Medeterinae, with a nearly ubiquitous global distribution. Phylogenetic relationships within Medetera and between Medetera and four other medeterine genera were investigated using mitochondrial (COI, 16S) and nuclear (18S) markers to test morphological hypotheses. Our results confirm most of Bickel's hypotheses. Thrypticus Gerstäcker shows a sister-group relationship with Medetera + Dolichophorus Lichtwardt. The Medetera species included here split into two clades. One clade corresponds to the M. diadema L. — veles Loew species group sensu Bickel. The second clade is largely composed of the M. apicalis (Zetterstedt) species group sensu Bickel and the M. aberrans Wheeler species group sensu Bickel + Dolichophorus. Although most Medeterinae are associated with plants (mainly trees), species in at least two separate lineages demonstrate a secondary return to terrestrial habitats. The implication of this evolutionary phenomenon is briefly discussed.
分子标记系统发育分析揭示密蝇科生态谱系(双翅目:密蝇科)
摘要:medeta Fischer von Waldheim是medeta科中种类最多的属,在全球几乎无处不在。利用线粒体(COI, 16S)和细胞核(18S)标记研究了medeta属内和medeta与其他四个medeta属之间的系统发育关系,以验证形态学假设。我们的结果证实了比克尔的大部分假设。Thrypticus Gerstäcker与medeta + Dolichophorus Lichtwardt为姊妹类群。这里所说的米底亚鱼分为两个分支。一个分支对应于m.d adema L. veles Loew种群sensu Bickel。第二支系主要由m.s apicalis (Zetterstedt)种群sensu Bickel和m.s aberrans Wheeler种群sensu Bickel + Dolichophorus组成。虽然大多数medetinae与植物(主要是树木)有关,但至少有两个不同谱系的物种显示出二次返回陆地栖息地。本文简要讨论了这一进化现象的含义。

期刊介绍: French translation follows/le français suit Published since 1868, this peer-reviewed bimonthly publication is the official journal of the Entomological Society of Canada. Available via the internet and with hardcopy distribution to 55 countries, its research papers and notes are relevant to entomologists and other biologists around the world. In addition to being a venue for topical reviews and forum discussion, The Canadian Entomologist publishes current research in all facets of entomology, including systematics and morphology, molecular and developmental biology, ecology and behaviour, biodiversity and evolution, insect management, entomological techniques, and other relevant subject areas. Contributions are published in English or French. Authors will not pay page charges, and will experience fast, high quality reviews of their papers.Publiée depuis 1868, cette publication bimestrielle avec comité de lecture est la revue officielle de la Société d’entomologie du Canada. Disponible sur Internet et distribuée en format papier dans 55 pays, ses articles de recherche et ses notes sont pertinents pour les entomologistes et autres biologistes de par le monde. En plus d’être une plate-forme pour des revues thématiques et un forum de discussion, The Canadian Entomologist publie la recherche actuelle sur toutes les facettes de l’entomologie, incluant la systématique et la morphologie, la biologie moléculaire et développementale, l’écologie et le comportement, la biodiversité et l’évolution, la gestion des insectes, les techniques entomologiques et d’autres domaines pertinents. Les contributions sont publiées en français ou en anglais. Les auteurs ne paient aucun frais de publication, et recevront une révision rapide et de grande qualité de leurs articles.
