摘要
来自花粉甲虫亚科成员的最新分子和形态学数据表明,有必要将Sagittogethes Audisio和Cline属(包括主要分布在西古北界的物种)分离为两个不同的(尽管相关)属,即Sagittokethes和Teucriogethes gen.n,包括西欧的蒙昧Meligethes Erichson,1845年作为其模式种,包括不到十个物种,分布在西部的伊比利亚半岛和北非,以及东部的中国和日本之间。所有的物种都利用Teucrium L.(Lamiacaeae:Ajugoideae)属的成员作为幼虫寄主植物。形态学和生物组学信息以及分子数据清楚地表明了更新这两个分支的分类位置的必要性。根据分子证据,新属代表了Thymogethes Audisio和Cline,2009年的姐妹群,而其余Sagittogether分类群与Meligethinae的其他Lamiaceae相关属的姐妹群关系仍不确定。在这个新属中,现存的、罕见的西地中海物种T.minutus(C.N.F.Brisout de Barneville,1863)似乎占据了一个孤立的位置。
Re-examination of the genus-level taxonomy of the pollen beetle subfamily Meligethinae – Part 1. Sagittogethes Audisio and Cline 2009 and allied genera; with description of a new genus (Coleoptera: Nitidulidae)
Recent molecular and morphological data derived from members of the pollen-beetle subfamily Meligethinae suggest the need to separate the genus Sagittogethes Audisio and Cline, 2009, including species mostly distributed in Western Palaearctic areas, into two distinct (although related) genera, Sagittogethes and Teucriogethes gen. n. This new genus, comprising the Western European Meligethes obscurus Erichson, 1845 as its type species, includes less than ten species distributed between the Iberian Peninsula and North Africa westward, and China and Japan eastward. All inclusive species utilize members of the genus Teucrium L. (Lamiacaeae: Ajugoideae) as larval host-plants. Morphological and bionomical information, and molecular data clearly demonstrate the necessity for updating the taxonomic position of the two clades. Based on molecular evidence, the new genus represents the sister-group of Thymogethes Audisio and Cline, 2009, while the sister-group relationships of the remaining Sagittogethes taxa with other Lamiaceae-associated genera of Meligethinae remain uncertain. Within the new genus, the relictual and rare Western Mediterranean species T. minutus (C.N.F. Brisout de Barneville, 1863) seems to occupy an isolated position.
期刊介绍:
Fragmenta entomologica is devoted to publishing high quality papers dealing with Arthropod biodiversity. It publishes research articles, short scientific notes, reviews articles, comments and editorials. The core scope of the journal includes Taxonomy, Systematics, Molecular phylogeny, Morphology, Paleontology, Biodiversity, Biogeography, Evolutionary biology, Conservation biology, Ecology, Ethology and Applied Entomology, and embraces all terrestrial, freshwater and brackish water Arthropods. Merely faunistic papers might be considered for publication only in the following cases: papers including relevant and significant new data emphasizing the conservation priority of rare, protected or endangered arthropods and their habitats; papers concerning with important newly introduced pest species; papers concerning with very poorly known geographic areas from scarcely investigated countries.
