Taxonomic and nomenclatorial revision of the genus Cheilonycha Lacordaire, 1842 with type species Cheilonycha chalybea (by original monotypy), based on Cicindela chalybea Dejean, 1825, is presented. It is concluded here that a subsequent type designation by Horn (1910), who without any explanation mentioned Ch. auripennis (Lucas, 1857) as the type species of the genus, was unjustified and must be considered invalid according to ICZN (1999). Examinations of type specimens have revealed that Cheilonycha auripennis sensu auctorum (sensu Horn 1922 and subsequent authors) is a complex of taxa. As a result, one new subspecies of Ch. auripennis (Lucas, 1857) and one new species of the genus are described and the following taxa of Cheilonycha are recognized and presented here: Ch. chalybea (Dejean, 1825), Ch. a. auripennis (Lucas, 1857), Ch. a. chiquitosiana ssp. nov. and Ch. bucephalauripennis sp. nov. Type specimens of Ch. a. angustedilatata (W. Horn, 1922) based on Odontochila (Chilonycha) auripennis angustedilatata W. Horn, 1922, proved to be fully conspecific with the type specimens of Ch. auripennis based on Cicindela auripennis Lucas, 1857. Consequently, Ch. a. angustedilatata syn. nov. is treated here as a junior synonym of Ch. a. auripennis. The history of the taxonomy of these taxa, their distribution and biology, including photographs of the termitophilous habitat, relevant lectotype designations, descriptions (redescriptions respectively) and illustrations in colour photographs of the habitus, diagnostic characters and variability are provided.
本文基于1825年德让（Dejean）的虎甲属丽虎甲（Cicindela chalybea），对1842年拉科代尔（Lacordaire）建立的丽虎甲属（Cheilonycha）进行了分类和命名修订，其模式种为丽虎甲（Cheilonycha chalybea，基于原始单模式）。本文得出结论，霍恩（Horn，1910）后来未经任何解释将金翅丽虎甲（Ch. auripennis，卢卡斯（Lucas），1857）指定为该属的模式种是不合理的，根据国际动物命名委员会（ICZN，1999）的规定，必须视为无效。对模式标本的检查表明，金翅丽虎甲（Cheilonycha auripennis）的作者概念（即霍恩1922年及后续作者的概念）是一个分类群复合体。因此，描述了金翅丽虎甲（Ch. auripennis，卢卡斯，1857）的一个新亚种和该属的一个新种，并在此认可并列出了丽虎甲属的以下分类群：丽虎甲（Ch. chalybea，德让，1825）、金翅丽虎甲指名亚种（Ch. a. auripennis，卢卡斯，1857）、奇基托斯金翅丽虎甲新亚种（Ch. a. chiquitosiana ssp. nov.）和牛头金翅丽虎甲新种（Ch. bucephalauripennis sp. nov.）。基于1922年W.霍恩的狭翅金翅丽虎甲（Odontochila (Chilonycha) auripennis angustedilatata W. Horn）建立的狭翅金翅丽虎甲（Ch. a. angustedilatata，W.霍恩，1922）的模式标本，经证明与基于1857年卢卡斯的金翅丽虎甲（Cicindela auripennis）建立的金翅丽虎甲模式标本完全同种。因此，狭翅金翅丽虎甲（Ch. a. angustedilatata syn. nov.）在此被视为金翅丽虎甲指名亚种（Ch. a. auripennis）的次异名。提供了这些分类群的分类学史、分布和生物学信息，包括嗜白蚁栖息地的照片、相关选模式指定、描述（分别为再描述）以及成虫的彩色照片、鉴别特征和变异性。
