摘要

同时由于核糖体基因的延伸环区而减少了人工长分支（另见Jordal等人，2008）。数据在MrBayes（Ronquist&Huelsen-beck，2003）中进行了分析，并使用GTR+I+G模型对七个分区中的每一个分区摘要进行了基因组和位置划分（如果编码）。根据Chilodendron planicolle Schedl，1953，将Chilodenron Schedl恢复为一个有效的属。这是1836年在马达加斯加发现的Hylesinini Erichson部落的唯一代表，对几个基因的分子系统发育分析支持了与1920年的Hylesinopsis Eggers和其他假定近亲不同的位置。Chilodendron很可能是马达加斯加现存最古老的树皮甲虫谱系，可能起源于马达加斯加从印度次大陆分离后不久的白垩纪晚期。

Sexual dimorphism and phylogenetic position of Chilodendron (Coleoptera: Curculionidae: Scolytinae) - a long isolated lineage endemic to Madagascar

simultaneously reducing arti ﬁ cially long branches due to extended loop regions that characterize ribosomal genes (see also Jordal et al., 2008). The data were analysed in MrBayes (Ronquist & Huelsen-beck, 2003) and partitioned into genomes and positions (if coding) using a GTR+I+G model for each of the seven partitions Abstract. Chilodendron Schedl, 1953 is resurrected as a valid genus based on Chilodendron planicolle Schedl, 1953. This is the only representative of the tribe Hylesinini Erichson, 1836 found on Madagascar and a molecular phylogenetic analysis of several genes supports a position separate from Hylesinopsis Eggers, 1920 and other putatively close relatives. It is likely that Chilodendron is the oldest living lineage of bark beetles on Madagascar and possibly originated in the late Cretaceous not long after the separation of Madagascar from the Indian subcontinent.

期刊介绍： EJE publishes original articles, reviews and points of view on all aspects of entomology. There are no restrictions on geographic region or taxon (Myriapoda, Chelicerata and terrestrial Crustacea included). Comprehensive studies and comparative/experimental approaches are preferred and the following types of manuscripts will usually be declined: - Descriptive alpha-taxonomic studies unless the paper is markedly comprehensive/revisional taxonomically or regionally, and/or significantly improves our knowledge of comparative morphology, relationships or biogeography of the higher taxon concerned; - Other purely or predominantly descriptive or enumerative papers [such as (ultra)structural and functional details, life tables, host records, distributional records and faunistic surveys, compiled checklists, etc.] unless they are exceptionally comprehensive or concern data or taxa of particular entomological (e.g., phylogenetic) interest; - Papers evaluating the effect of chemicals (including pesticides, plant extracts, attractants or repellents, etc.), irradiation, pathogens, or dealing with other data of predominantly agro-economic impact without general entomological relevance.
