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.本研究对大力神犀金龟（即Dynastes属MacLeay于1819年建立的Dynastes亚属）的分类学处理进行了全面修订，确认该类群包含2个主要物种类群以及15个有效物种。原被定为亚种的10个分类单元现已被提升为独立物种，分别为：Dynastes moroni Nagai, 2005（状态修订）、Dynastes bleuzeni Silvestre & Dechambre, 1995（新等级）、Dynastes ecuatorianus Ohaus, 1913（新等级）、Dynastes lichyi Lachaume, 1985（新等级）、Dynastes morishimai Nagai, 2002（新等级）、Dynastes occidentalis Lachaume, 1985（新等级）、Dynastes paschoali Grossi & Arnaud, 1993（新等级）、Dynastes reidi Chalumeau, 1977（新等级）、Dynastes septentrionalis Lachaume, 1985（新等级）以及Dynastes trinidadensis Chalumeau & Reid, 1995（新等级）。学名Dynastes hercules (Linnaeus, 1758) 的使用范围现已被限定为仅指代瓜德罗普岛与多米尼加岛上的两个种群。本次分类修订还详细讨论了此次分类变动的依据，即基于遗传、表型与生态数据的差异，以及地理重叠范围的估算结果。本研究同时提供了基于Illumina测序数据构建的更新版Dynastes属系统发育树，用于探讨该属物种间的演化亲缘关系。
