The biodiversity of Liogenys Guérin-Méneville, 1831 (Coleoptera: Scarabaeidae: Melolonthinae: Diplotaxini) from the southern South American Transition Zone and boundaries is presented. Four new species are described: L. brachyclypeata Cherman, new species; L. lucialmeidae Cherman, new species; L. martinezi Cherman, new species; and L. maxillaricuspis Cherman, new species. The synonymy of L. flaveola Moser, 1924 (= L. kadleci Frey, 1970) is proposed. Lectotypes are designated for L. flavida Moser, 1918; L. pallidicornis Blanchard, 1851 (currently L. xanthocera Harold, 1869); and L. rufoflava Moser, 1918. Redescriptions are provided for all the species mentioned above plus L. calcarata Frey, 1970 and L. kunzteni Moser, 1921, as well as an identification key and updated geographical distributions to all species in the region. All species are present in the Monte province, except of L. kuntzeni (Andean provinces of Chile). Liogenys flavida and L. rufoflava have the broadest distribution, the latter here expanded to Paraguay and Chile.
来自南美南回归线过渡带和边界的 Liogenys Guérin-Méneville, 1831 （鞘翅目：金龟子科：鳃角金龟亚科：Diplotaxini）的生物多样性介绍。描述了四个新物种：L. brachyclypeata Cherman，新物种；L. lucialmeidae Cherman，新物种；L. martinezi Cherman，新物种；和 L. maxillaricuspis Cherman，新物种。提出了 L. flaveola Moser, 1924（= L. kadleci Frey, 1970）的同义词。为 L. flavida Moser, 1918；L. pallidicornis Blanchard, 1851（目前为 L. xanthocera Harold, 1869）和 L. rufoflava Moser, 1918 指定了模式标本。对上述所有物种以及 L. calcarata Frey, 1970 和 L. kunzteni Moser, 1921 进行了重新描述，并提供了该地区所有物种的鉴别钥匙和更新的地理分布。除了 L. kuntzeni（智利安第斯山脉省份）之外，所有物种都存在于蒙特区。L. flavida 和 L. rufoflava 的分布最广，后者的分布范围扩展到了巴拉圭和智利。
