Data from: The Hercules beetles (subgenus Dynastes, genus Dynastes, Dynastidae): a revisionary study based on the integration of molecular, morphological, ecological, and geographic analyses

The taxonomic treatment of Hercules beetles (subgenus Dynastes of the genus Dynastes MacLeay, 1819) is revised, with the recognition of two major species groups and 15 species. The following 10 taxa, originally designated as subspecies, have been elevated to full species status: Dynastes moroni Nagai, 2005 (REVISED STATUS); Dynastes bleuzeni Silvestre & Dechambre, 1995 (NEW STATUS); Dynastes ecuatorianus Ohaus, 1913 (NEW STATUS); Dynastes lichyi Lachaume, 1985 (NEW STATUS); Dynastes morishimai Nagai, 2002 (NEW STATUS); Dynastes occidentalis Lachaume, 1985 (NEW STATUS); Dynastes paschoali Grossi & Arnaud, 1993 (NEW STATUS); Dynastes reidi Chalumeau, 1977 (NEW STATUS); Dynastes septentrionalis Lachaume, 1985 (NEW STATUS); and Dynastes trinidadensis Chalumeau & Reid, 1995 (NEW STATUS). The use of the species name Dynastes hercules (Linnaeus, 1758) is restricted to only two island populations from Guadeloupe and Dominica. This taxonomic revision is accompanied by discussions of the basis for these taxonomic changes, i.e. based on differences in genetic, phenotypic, and ecological data and on estimates of geographic overlap. An updated Dynastes beetle phylogeny based on Illumina sequencing data is also presented for a discussion of the evolutionary relationships among the species.

本研究对大力士甲虫（犀金龟属Dynastes MacLeay, 1819下的Dynastes亚属）的分类学处理进行了系统修订，共识别出两个主要物种群与15个有效物种。原被划定为亚种的10个分类单元现已被提升为独立物种，具体如下：2005年由Nagai发表的Dynastes moroni Nagai, 2005（分类地位修订）；1995年由Silvestre与Dechambre发表的Dynastes bleuzeni Silvestre & Dechambre, 1995（新等级确立）；1913年由Ohaus发表的Dynastes ecuatorianus Ohaus, 1913（新等级确立）；1985年由Lachaume发表的Dynastes lichyi Lachaume, 1985（新等级确立）；2002年由Nagai发表的Dynastes morishimai Nagai, 2002（新等级确立）；1985年由Lachaume发表的Dynastes occidentalis Lachaume, 1985（新等级确立）；1993年由Grossi与Arnaud发表的Dynastes paschoali Grossi & Arnaud, 1993（新等级确立）；1977年由Chalumeau发表的Dynastes reidi Chalumeau, 1977（新等级确立）；1985年由Lachaume发表的Dynastes septentrionalis Lachaume, 1985（新等级确立）；以及1995年由Chalumeau与Reid发表的Dynastes trinidadensis Chalumeau & Reid, 1995（新等级确立）。本研究将Dynastes hercules (Linnaeus, 1758)这一物种学名的适用范围严格限定为仅分布于瓜德罗普岛与多米尼加岛的两个岛屿种群。本次分类学修订还对各项分类变更的依据进行了详细讨论，相关依据包括遗传、表型与生态数据的差异，以及地理重叠范围的估算结果。本研究同时基于Illumina测序（Illumina sequencing）数据构建了更新版的犀金龟属系统发育树，用以探讨该属内各物种间的演化亲缘关系。
