A taxonomic revision of the Liogenys Guérin-Méneville, 1831 (Coleoptera: Scarabaeidae: Melolonthinae: Diplotaxini) from the Chacoan Biogeographical Province is presented. Liogenys now includes 92 species, including four new species described here: L. neoforcipata Cherman, new species; L. foveata Cherman, new species; L. isotarsis Cherman, new species; and L. truncata Cherman, new species; and the female of L. tarsalis Moser is described for the first time. Six new synonymies are proposed: L. denticulata Moser, 1918 is a new synonym of L. denticeps Blanchard, 1851; L. ophtalmica Frey, 1973 is a new synonym of L. bidenticeps Moser, 1919; L. mendozana incisa Frey, 1969 is a new synonym of L. mendozana Moser, 1918; L. flavicollis Blanchard, 1851 and L. fulvescens Blanchard, 1851 are new synonyms of L. pallens Blanchard, 1851; and L. densicollis Moser, 1921 is a new synonym of L. opacicollis Fairmaire, 1892. Liogenys cribricollis Moser, 1921 species status is revalidated from its synonymy with L. densicollis. A neotype is designated for Liogenys mendozana incisa Frey, 1969, as well as lectotypes for: L. bruchi Moser, 1924; L. cribricollis, L. denticulata, L. denticeps, L. fulvescens, L. latitarsis Moser, 1918; L. mendozana Moser, 1918; L. obscura Blanchard, 1851; L. opacicollis; and L. pallens. Redescriptions and/or diagnoses and updated geographical distributions are provided for 16 species. Six species previously known only from Argentina have their distribution expanded to Bolivia (L. mendozana; L. opacicollis; L. rectangula Frey, 1969), Paraguay (L. nigrofusca Moser, 1918; L. pallens), or to both of these countries (L. latitarsis).
本文对来自查科生物地理省的李氏犀金龟属（Liogenys Guérin-Méneville，1831）（鞘翅目：金龟科：鳃金龟亚科：双带犀金龟族）进行了分类修订。李氏犀金龟属现包含92个物种，其中包括在此描述的4个新物种：新种李氏新钳犀金龟（Liogenys neoforcipata Cherman）、新种李氏凹点犀金龟（Liogenys foveata Cherman）、新种李氏等跗犀金龟（Liogenys isotarsis Cherman）和新种李氏截形犀金龟（Liogenys truncata Cherman）；首次描述了李氏跗犀金龟（Liogenys tarsalis Moser）的雌性。提出了6个新异名：李氏细齿犀金龟（Liogenys denticulata Moser，19）是李氏齿头犀金龟（Liogenys denticeps Blanchard，1851）的新异名；李氏眼斑犀金龟（Liogenys ophtalmica Frey，1973）是李氏双齿头犀金龟（Liogenys bidenticeps Moser，1919）的新异名；李氏门多萨犀金龟刻点亚种（Liogenys mendozana incisa Frey，1969）是李氏门多萨犀金龟（Liogenys mendozana Moser，1918）的新异名；李氏黄颈犀金龟（Liogenys flavicollis Blanchard，1851）和李氏淡褐犀金龟（Liogenys fulvescens Blanchard，1851）是李氏淡色犀金龟（Liogenys pallens Blanchard，1851）的新异名；李氏密颈犀金龟（Liogenys densicollis Moser，1921）是李氏暗颈犀金龟（Liogenys opacicollis Fairmaire，1892）的新异名。李氏筛颈犀金龟（Liogenys cribricollis Moser，1921）的物种地位从其与李氏密颈犀金龟的同物异名中重新确认。指定李氏门多萨犀金龟刻点亚种（Liogenys mendozana incisa Frey，1969）的新模标本，以及李氏布鲁氏犀金龟（Liogenys bruchi Moser，1924）、李氏筛颈犀金龟、李氏细齿犀金龟、李氏齿头犀金龟、李氏淡褐犀金龟、李氏宽跗犀金龟（Liogenys latitarsis Moser，1918）、李氏门多萨犀金龟（Liogenys mendozana Moser，1918）、李氏暗犀金龟（Liogenys obscura Blanchard，1851）、李氏暗颈犀金龟和李氏淡色犀金龟的选模标本。提供了16个物种的重新描述和/或诊断以及更新后的地理分布。6个以前仅在阿根廷已知的物种，其分布范围扩展到了玻利维亚（李氏门多萨犀金龟；李氏暗颈犀金龟；李氏矩犀金龟（Liogenys rectangula Frey，1969））、巴拉圭（李氏黑褐犀金龟（Liogenys nigrofusca Moser，1918）；李氏淡色犀金龟）或这两个国家（李氏宽跗犀金龟）。
